Apple released macOS 27 Golden Gate on September 14, 2026, but development hasn’t stopped. Just two days later on September 16, Apple issued the first developer beta of macOS 27.2, beginning testing of the operating system’s next major point update. Yes, that’s macOS 27.2, not macOS 27.1.
The macOS 27.2 beta gives developers and testers early access to Apple’s latest fixes, refinements and any features that weren’t ready for the initial Golden Gate release.
However, as with any beta software, it may introduce bugs, compatibility problems and poorer battery life so we recommend caution if you wish to install it.
Here’s everything you need to know about the latest macOS beta, including what’s new, when the next public beta is likely to arrive and whether you should install it.
Apple offers two beta streams: a developer beta and a public beta. The public beta allows enthusiasts and early adopters to test upcoming changes before they are released to everyone. You need to join Apple’s Beta Software Program to access it.
The latest Mac beta is macOS 27.2 beta 1, which Apple released to registered developers on September 16, 2026. It arrived two days after the public release of macOS 27 Golden Gate.
The corresponding macOS 27.2 public beta is expected shortly. Public betas usually follow developer betas, although Apple does not guarantee a particular schedule.

Apple has not announced any major consumer-facing additions in macOS 27.2 beta 1. The following changes are expected though:
We’ll update this section as changes are discovered.

Installing the macOS beta lets you test Apple’s next round of features, fixes and refinements before their public release. Most Mac users should remain on the standard version of macOS 27, particularly if they rely on their Mac for work.
Install if…
Wait if…
| Who are you | Should you install? |
|---|---|
| A developer testing apps | Consider the developer beta |
| An enthusiast with a spare Mac | Consider the public beta |
| General user with one Mac | Stay on macOS 27 |
Installing pre-release software on a primary device carries several risks.
If you decide to install the beta, take the following precautions:

The process for installing a macOS beta depends on whether you are seeking the Developer Beta or the Public Beta. Apple simplified this process a few years ago, removing the need for a paid developer account to access early builds.
The first step is to join Apple’s beta testing program. We explain how to do that in a separate article.
You will need to register your account either as a public beta tester or as a developer in order to enable beta updates on your Mac.
To install the beta follow these steps:
As long as you are a registered developer or enrolled in the public beta program, when the relevant macOS Beta becomes available, it will also show up on your Mac.
Once you are running the beta, the updates will come through to your Mac automatically; you just need to go to Software Update in System Settings and click to install. See How to install macOS.
If you just want a free Apple Developer account so you can access the beta, you can get this via Xcode or the Apple Developer app in iOS. Here’s how to do it via the Apple Developer app on an iPhone:
If you wish to actually publish applications to the App Store or receive support, you’ll need to pay $99/£79 per year for a paid account. You can compare the free and paid accounts here.
Anyone can run the macOS beta, but to do so, you do need to register for either the developer beta, the public beta, or both.
Apple offers both developer and public beta programs for macOS, enabling all interested users to test pre-release versions of the operating system. While both betas provide early access to new features, they cater to different user profiles based on technical expertise and risk tolerance. Beta software tends to be buggy so the more stable public beta version may be preferable, but even that will not be bug-free.
In the past, the developer beta was only available to developers who had paid to join Apple’s Developer Program (which costs $99/£79). However, for a couple of years now, Apple has opened up the developer beta to registered developers with free developer accounts. We explain how to get a free developer account below.
If you decide you no longer want to run the beta version of macOS read this: How to remove the macOS beta.
Since 2023, the Developer Beta has been available to anyone who registers as a developer, even if they aren’t a paid-up member of Apple’s Developer Program. As a result, people with a basic free developer account can download the new macOS developer beta (we show you how to register below).
Whether you should download the developer beta if you aren’t a developer is another question. We don’t recommend you install the developer beta if you aren’t a developer. Instead, our recommendation is to use the public beta (the first version of which usually arrives in July).
There are a few differences between the public and developer betas. The public beta is not the same as the beta that is released through the developer program. The public beta typically launches after the developer beta has undergone initial testing and refinement
Developers get updates to their beta first, and possibly more frequently. But you should keep in mind that betas are by nature not stable, and because the public beta comes after the developer beta it could be a little safer to install.
The most significant difference is probably the motive of the testers: Developers usually have the aim of ensuring their apps work when the updated macOS is released to the general public, while public beta testers are essentially helping Apple detect bugs and offering feedback on the features. Because of this, developers may get to test new features not available in the public beta.
If you want to get the public beta the first thing you need to do, if you haven’t already, is join Apple’s beta programs read this for more information: How to become an Apple beta tester.
By its nature, a beta has the potential to be unstable. Therefore, it’s not advised that you install it on a Mac that you rely on. If you have a second Mac that isn’t mission-critical, then install it there. We strongly recommend that you don’t risk all by putting the macOS beta on your primary Mac, especially not in the early days of the beta development.
If you don’t have a second Mac, there are a couple of ways you could run macOS beta on your Mac without running the risk of losing data or finding your Mac stops working:
We discuss the safety of the macOS beta and the risks you might be taking in more detail in a separate article.
Update your software: We recommend you have the latest full version of macOS installed, although Apple says that the macOS Developer Beta Access Utility requires macOS 10.8 or later.
Make space: We’d recommend at least 25-30GB of available space because the macOS betas tend to be very large. If you end up requiring more space, read: How to free up space on Mac. Note that we always recommend that you have at least 10% space free on your Mac at any time, so if you don’t have that, expect problems!
Back up: Before you install a beta on your Mac, you should make a backup of your data and files. You can find out how to use Time Machine to back up your Mac. We also have a round-up of suitable backup solutions.
Should you come across an error or a bug, you should use the Feedback Assistant app to provide feedback to Apple. Launch the app and follow the appropriate steps, selecting the area about which you’re providing feedback and then any specific sub-area. Then describe your issue in a single sentence, before providing a more detailed description, including any specific steps that reproduce the issue. You’ll also be able to attach other files.
You’ll also have to give permission for the Feedback Assistant app to collect diagnostic information from your Mac.
It won’t always be obvious whether something is a bug or just not as easy to use as you might have hoped. Either way, if your feedback is that something appears to work in an illogical way, Apple will want to know that.
If you are having trouble with a third-party app, you can let Apple know by reporting it through the 3rd-party Application Compatibility category in the Feedback Assistant. However, we’d suggest that you also provide feedback to the app’s developer, who will no doubt be grateful.
Beta users can move to the finished release once its build is newer than – or equivalent to – the beta installed. Read: How to leave the macOS beta.
According to Apple and the license agreement all beta testers must agree to, the beta is “Apple confidential information”. By accepting those terms, you agree not to discuss your use of the software with anyone who isn’t also in the Beta Software Program. That means you can’t “blog, post screenshots, tweet, or publicly post information about the public beta software.”
However, you can discuss any information that Apple has publicly disclosed; the company says that information is no longer considered confidential.
You can always revert to an earlier version of macOS, though depending on how you back up, it’s not necessarily a painless process.
Start by making sure the data on your drive is backed up, then erase the drive and install the latest public version of macOS. When you first start up your Mac, you can use the Migration Assistant to import your data from the backup. Here’s a more detailed tutorial on downgrading from the macOS beta and we also have a tutorial on downgrading to an older version of the Mac OS.
Yes, the macOS beta is free to download for both developers and the general public. Apple offers two distinct tracks for testing pre-release software: the Developer Beta and the Public Beta, both of which are now accessible without a paid subscription.
Yes, you can go back to the stable version of macOS from a beta, but the complexity of the process depends on whether the final version of that software has been released yet.
If you are running macOS 27.2 beta and want to return to the current public release of macOS 27, simply turning off Beta Updates will stop future beta installations, but it will not immediately downgrade the Mac. To return before Apple releases an equivalent public build, you may need to erase the Mac and reinstall macOS, then restore data from a backup made before installing the beta.
Installing a macOS beta on your primary computer is generally not recommended due to the inherent risks of using unfinished software. While beta programs offer early access to new features, they are designed for testing and often contain significant bugs that can disrupt your daily workflow.
You do not need a paid Apple Developer account to install the macOS beta. While access to developer betas was previously restricted to those paying a $99/£79 annual fee, Apple changed this policy in 2023 to allow anyone with a free developer account to access these builds. Alternatively, you can join the Public Beta program, which is also free and accessible to anyone with a valid Apple ID.
New macOS beta versions are typically released every one to two weeks, with the frequency increasing as the final public release date approaches. The beta updates refine features and address bugs identified by testers.
The beta is generally safe to test, but it may contain bugs that cause crashes, poor battery life, app compatibility issues, or data loss. Always back up your Mac before installing.
Many apps will work normally, but some third-party software may crash, perform poorly, or not launch at all until developers release updates.
Apple Intelligence is back, baby! That's right: Two years after its initial launch, Apple is giving its generative AI features their first significant upgrade, along with a new version of Siri that the company has been strongly insinuating would be a part of each of the last two macOS releases, without ever actually announcing a release date.
Generative AI is unavoidable if you install macOS 27 Golden Gate. I'm being very literal: There used to be a toggle you could hit if you wanted to turn off Apple Intelligence and delete the gigabytes' worth of AI models it would download to your disk, and now there isn't. Apple Intelligence defines the Golden Gate release, in everything from its marketing to its features to the chips it runs on to the amount of space it takes on your disk. Ready or not, here it is.
But if you can manage to look past that fanfare somehow, the operating system underneath Apple Intelligence is getting the kind of update that macOS users usually proclaim to like. Golden Gate addresses the most irritating of macOS 26 Tahoe's design sins, adds a big pile of incremental improvements, and promises a bunch of under-the-hood fit-and-finish optimizations to make common tasks feel just a little faster and more reliable than before.

Upgrading macOS doesn’t always go as planned. A new release might slow down your Mac, break essential apps, introduce bugs, or simply change features you rely on. If you’re wishing you could go back to the version you had before, the good news is that you can downgrade macOS.
While reverting a macOS update is generally easier than downgrading an iOS update, it’s not as simple as installing macOS. It is a multi-step process that typically requires wiping your Mac’s internal drive, as Apple does not allow installing an older version of the operating system directly over a newer one.
Because you need to erase your Mac’s internal drive before you can reinstall an older version of the operating system, your data must be backed up first. The exact process depends on whether you created a backup before upgrading macOS.
In this guide, we run through the safest way to revert to an earlier version of macOS, explain what works (and what doesn’t), and help you choose the best method for your situation.
Note: macOS 27 Golden Gate runs only on Macs with Apple silicon, so the main Golden Gate-to-Tahoe instructions in this article are for Apple-silicon Macs. We cover older Intel Macs separately below for readers using this guide to downgrade an earlier version of macOS.
Yes, it is possible to downgrade from macOS Golden Gate (macOS 27) to macOS Tahoe (macOS 26), but the process is complex and requires you to completely wipe your Mac’s data and install the older version of macOS.
Before you begin, confirm that your Mac can run Tahoe. A Mac cannot install a version of macOS older than the version it originally shipped with. A Mac introduced with Golden Gate may therefore be unable to run Tahoe, even if another Mac with a similar processor can. Check Apple’s compatibility information before erasing anything.
You need the following:
Follow these steps, which we explain in more detail below:
Foundry
Apple issues multiple point updates throughout the year. If something breaks following an update, you may want to return to the previous release—for example, by downgrading from macOS 27.1 to macOS 27.0. The same principle applies to subsequent Golden Gate updates.
Rolling back a point update can be more difficult than downgrading from Golden Gate to Tahoe because you need the full installer for the exact earlier release. Apple generally offers only the latest installer for each major version of macOS, so the macOS 27.0 installer may no longer be available after macOS 27.1 has been released.
However, you may be able to obtain the required version of macOS using Terminal. We detail how to do this below (see step 2). As of September 2026 there were various version installers of Tahoe and Sequoia available using this method.
A Time Machine backup cannot provide the missing installer or reinstall the earlier operating system. If you have access to the appropriate full installer, you can create bootable installation media and follow the erase-and-install process described below. If Apple no longer offers that release and you did not retain its installer, an ordinary downgrade may not be possible.
The steps below will help you revert to macOS Tahoe. Before you start, remember that you must wipe your Mac and perform a clean installation of Tahoe.
Reminder: This will erase your Mac, so make sure you have a backup of important files before continuing.
Backing up your Mac is the most critical step before a downgrade because the process requires erasing your startup drive, which removes all locally stored data. If you don’t already have a backup, you will need to make one.
Time Machine is the standard backup method for most Mac users, but restoring data from a newer version of macOS to an older one can present problems. A Time Machine backup made under Golden Gate may contain Photos libraries, Mail databases, settings, application data, and versions of apps that are not compatible with Tahoe.
A backup made while the Mac was still running Tahoe is therefore the safest one to use. However, it won’t contain files created or changed after the upgrade to Golden Gate. If Golden Gate is still working, make a separate copy of every irreplaceable document you have created or modified since upgrading.
Before recovering data from a Time Machine backup, you must install Tahoe on the Mac. You can then use Setup Assistant or Migration Assistant to transfer compatible accounts, apps, settings, and files from the backup.
If you store documents in iCloud Drive or use iCloud Photos, fully synchronized items should become available again when you sign in to the same Apple Account after reinstalling macOS. Before erasing the Mac, check iCloud.com or another Apple device to confirm that important documents, photos, and videos have uploaded successfully. Remember that iCloud is a synchronization service rather than a separate backup, so keep an independent copy of irreplaceable files where possible.
To ensure your data remains accessible after you return to an older version of macOS, consider these backup strategies:
For more help read: How to back up a Mac.
Step back to Tahoe, if your Mac can run it.
Thomas Armbrüster
The version of macOS you install must be compatible with your Mac. A Mac that was upgraded to Golden Gate can be returned to Tahoe only if that model supports Tahoe. A model that first shipped with Golden Gate cannot be downgraded to Tahoe.
For example, Apple announced the M6 Mac mini before Golden Gate was released, but the Mac did not ship until afterward and requires macOS 27. Always check that your model supports the older operating system before erasing the Mac.
Check our lists of Macs compatible with Golden Gate and Tahoe.
You can download old versions of macOS from Terminal, if they aren’t on the Mac App Store.
Foundry
The next stage is to get the full installer for the version of macOS you require. In most cases, the Mac used to download the installer must itself be compatible with the version of macOS you require.
For this downgrade you need the Tahoe installer, not the Golden Gate installer. For Tahoe and earlier installers, see our guide to downloading older versions of macOS.
Normally Apple makes older versions of macOS available to download from the Mac App Store. For example, you can get Sequoia, Sonoma and Ventura this way. However, as of September 2026, Apple’s hasn’t made Tahoe available from the Mac App Store. We expect that it eventually will do so, but in the meantime the best way to get the Tahoe installer it to use Terminal.
Terminal method
Open Terminal.
Type in the following:softwareupdate --fetch-full-installer --full-installer-version [number]
You need to include the relevant version number. For example softwareupdate –fetch-full-installer –full-installer-version 26.6.2.
To see which installers Apple currently offers for that Mac, run:softwareupdate --list-full-installers
If Terminal reports that the update was not found, Apple may no longer offer that exact release, or it may not be compatible with your Mac.
When the download finishes, the full installer will appear in the Applications folder. Quit it if it opens automatically—you need to retain it to create the bootable installer.
In each case of the above screenshot the macOS installer is listed as Deferred: No, which means the installer is still available.
Mac App Store method
The installer will appear as an app named Install macOS Tahoe in the Applications folder.
As noted above, downgrading from one Golden Gate point release to another requires the full installer for the exact earlier release. Because Apple generally offers only the latest installer for each major version of macOS, the version you need may no longer be available unless you previously downloaded and retained it. A Time Machine backup cannot provide the missing installer or reinstall the earlier operating system.
Once you have it, you can use the bootable installer of Tahoe to downgrade your Mac.
Foundry
You cannot install Tahoe directly over Golden Gate. To install an older version of macOS, you need to create a bootable installer containing the Tahoe installation files.
You will need a USB flash drive or other external volume. A 32GB drive is recommended, although 16GB is sufficient for many older macOS installers. The drive will be erased during the process.
Follow our complete guide to creating a bootable macOS USB installer, selecting the instructions and
createinstallmedia Terminal command for macOS Tahoe.
The Tahoe command is:sudo /Applications/Install\ macOS\ Tahoe.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume
Replace MyVolume if your external drive has a different name. Make sure --volume contains two ordinary hyphens, not an en dash or em dash. The linked guide explains how to prepare the drive, run the command and troubleshoot the creation process.
Foundry
With the bootable Tahoe installer ready, the next step is to start your Mac from it rather than from the internal drive currently running Golden Gate.
Foundry
Warning: This step will permanently remove the local accounts, applications, settings and files stored on the Mac.
Erase All Content and Settings is not, by itself, a downgrade tool. It removes data and settings while retaining the installed operating system. To replace Golden Gate with Tahoe, you need to erase the startup volume from the bootable installer environment and then install Tahoe.
Finally, you can get Tahoe back on your Mac.
Foundry
With the internal startup volume erased, you can now install Tahoe from the bootable installer.
Foundry
After Tahoe is installed, the Mac will start in Setup Assistant.
If you have a Time Machine backup from before the Golden Gate upgrade, you can connect the backup disk and transfer your information during setup. Time Machine can transfer your accounts, apps, settings, and files after Tahoe has been installed, but it does not perform the operating-system downgrade, you need to do that first (as per the steps above).
If your only backup was made under Golden Gate, setting up the Mac as new and copying your documents back manually is the safest approach. This reduces the risk of importing an app, database, or setting that requires macOS 27. You can then reinstall Tahoe-compatible versions of your apps individually.
Once your Mac is set up you can copy your data from your backup.
Foundry
A backup made while the Mac was still running Tahoe is the best one to use. To transfer its contents during Setup Assistant, choose the option to transfer information From a Mac, Time Machine backup, or startup disk. Connect the backup disk, select the appropriate backup, and choose the accounts, apps, settings, and files you want to transfer.
If you have already completed setup:
The selected backup will not contain anything created or changed after it was made. Copy those newer documents back from the separate backup you created before erasing the Mac.
Check the following:
Installing macOS 27 may also update the Mac’s firmware. Installing Tahoe later does not necessarily roll that firmware back; a macOS downgrade and a firmware downgrade are not the same operation.
Reversing an upgrade carries a number of wrinkles and pitfalls. Many are caused by changes in file formats and settings between versions of the operating system. If you create a document or work on a file in a newer version of macOS and then try to open it in an older version, it may not work.
Where possible, export important documents in standard or widely compatible formats before erasing the Mac. For example, you could export a document as RTF or PDF in addition to retaining its native version.
Whenever you perform a clean installation of macOS, it’s a good idea to take screenshots of custom settings in apps and System Settings. That makes it easier to re-create them later.
Make a note of account details for anything you set up while running the newer operating system. Export bookmarks if they are not synchronized, and make sure you have access to application installers, subscriptions and license codes.
If you use Dropbox, OneDrive, Google Drive or another cloud storage service, make sure synchronization has completed before starting the downgrade. Files visible in a synchronized folder may not have finished uploading.
If you use Gmail, iCloud Mail or another IMAP service, make sure recent mail and drafts have synchronized. If you use a POP3 account, manually back up locally stored mail before erasing the Mac.
Finally, keep the Golden Gate backup intact until you have confirmed that Tahoe starts correctly and that all essential documents have been recovered. Do not erase or repurpose the backup drive merely because the downgrade appears to have completed.
Golden Gate does not support Intel Macs. These instructions are for if you want to downgrade an earlier macOS release on an Intel Mac.
Intel Macs start from a bootable installer by holding Option (Alt) at startup. Macs with the Apple T2 Security Chip may also need Startup Security Utility configured to allow booting from external or removable media. See our bootable macOS installer guide for the complete Apple-silicon, Intel and T2 instructions.
An Intel Mac may also be able to use Internet Recovery. Start it while holding:
Internet Recovery cannot install a version older than the one the Mac supports, and the exact version offered can vary.
Die Funktion „Bereinigen“ in Fotos, mit der sich störende Objekte bisher aus einem Bild entfernen ließen, war nur begrenzt nützlich. Bei kleineren und nicht zu komplexen Objekten konnte das Ergebnis zwar brauchbar sein, primär in den Fällen, in denen der zuvor von dem Objekt verdeckte Hintergrund einfache Strukturen hatte. Aber für aufwendigere Retuschen mussten Sie andere Werkzeuge verwenden.
In macOS 27 Golden Gate bekommt Fotos jetzt Zugriff auf Apple Intelligence, um unerwünschte Objekte mithilfe von KI zu entfernen. Mit der KI können Sie aber nicht nur besser retuschieren. Bilder lassen sich nun auch erweitern, und Sie können die Bildperspektive ändern. Für alle diese Funktionen ist der Zugriff auf Apples Server notwendig. Ohne Internetverbindung geht es also nicht.
Die neuen Funktionen verlassen sich dabei auf Private Cloud Compute, also auf größere Modelle auf Servern mit Apple-Chip. Diese können komplexere Anfragen bearbeiten als lokale Modelle, sollen aber laut Apple die Privatsphäre der Anwender schützen.
Thomas Armbrüster
Wir haben in Fotos drei Bilder ausgewählt, und diese mit der neuen Funktion „Bereinigen“ bearbeitet. Dabei haben Sie die Wahl zwischen drei Einstellungen: „Hohe Qualität“, „Schnell“ und „Automatisch“. Bei „Automatisch“ entscheidet Fotos selbst, welches Verfahren angewendet werden soll. Zudem haben wir dieselben Bilder auch nochmals mit Fotos unter macOS 26 mit der Funktion „Bereinigen“ bearbeitet.
Thomas Armbrüster
Wählen wir die Option „Schnell“, entsprechen die Ergebnisse weitgehend denjenigen, die wir auch unter macOS 26 Tahoe bekommen. Bei zwei unserer Testbilder ist diese Option nicht brauchbar. Nur beim dritten Bild, bei dem wir ein Auto vor einer Kirche entfernen lassen, kann man mit dem Ergebnis leben.
Beim Bereinigen mit hoher Qualität braucht es einige Zeit, bis sich das Ergebnis einstellt. Ein Fortschrittsbalken zeigt jeweils an, wie weit die Bearbeitung fortgeschritten ist.
Es passiert bisweilen, dass man beim Aufnehmen eines Fotos den Bildausschnitt nicht gut genug gewählt hat und dann an den Bildrändern etwas abgeschnitten ist, etwa eine Kirchturmspitze oder eine Baumkrone. In Fotos können Sie nun mit der Funktion „Erweitern“ den Bildern an den Seiten neuen Inhalt hinzufügen. Dazu ziehen Sie an dem sich einblendenden Rahmen in die gewünschte Richtung. Das ist aber nicht endlos möglich, sondern nur in einem begrenzten Umfang.
Um ein Bild zu erweitern, bewegen Sie den sich einblendenden Rahmen in die gewünschte Richtung.
Thomas Armbrüster
Das Erweitern ist zudem sinnvoll, wenn Sie einen Horizont begradigen möchten, dabei das Bild dann aber an einer Stelle beschnitten wird. Der neue Bildinhalt wird von Apple Intelligence anhand der vorhandenen Bildinhalte berechnet und hinzugefügt. Das Bild ist dann aber teilweise von KI generiert, entspricht also nicht mehr ganz dem fotografierten Objekt. So kann insbesondere eine hinzugefügte Kirchturmspitze etwas anders aussehen als in der Realität.
Die dritte Funktion „Neu ausrichten“ ermöglicht es, die Perspektive eines Bildes zu ändern. Sobald Sie diese Funktion gewählt haben, blenden sich in der Werkzeugleiste mehrere Schieberegler ein, über die Sie einzelne Aspekte der Perspektive ändern können. Oder Sie bewegen den Mauszeiger über das Bild und bewegen den Bildinhalt, bis dieser ihren Vorstellungen entspricht.
Thomas Armbrüster
Auch beim Perspektivenwechsel generiert die KI neue Bildinhalte. Das Bild entspricht dann ebenfalls nicht mehr der Realität, sondern ist in Teilen von der KI generiert.
Die neuen Bildbearbeitungsfunktionen mithilfe von Apple Intelligence ermöglichen nicht unerhebliche Eingriffe in das Originalbild. Erkennbar ist das für einen Betrachter aber nicht. In diese Bilder wird ein unsichtbares Wasserzeichen eingebettet, das dann mit entsprechenden Werkzeugen erkannt werden kann.
Auf dieser Webseite von Apple steht dazu: „In Fotos, die mit Apple Intelligence bearbeitet worden sind, erscheint ein unsichtbares SynthID-Wasserzeichen. Daran lässt sich erkennen, welche Fotos mit KI bearbeitet worden sind.“
SynthID wurde von Google entwickelt und ist Open Source. Wir haben drei der von uns generierten Bilder an Gemini übergeben und gefragt, ob sie ein Wasserzeichen enthalten. Aber obwohl SynthID von Google stammt, wird kein Wasserzeichen erkannt. Vielleicht erkennt Gemini nur das Wasserzeichen in einem von Gemini selbst erstellten oder manipulierten Bild.
Thomas Armbrüster
O Mac se tornou um importante aliado de quem usa a máquina para rodar modelos de inteligência artificial locais — não é à toa que os Macs mini estão sendo muito visados nesse período de boom no mercado.
Caso use o Gemini (um dos principais nomes de chatbots, ao lado do ChatGPT e do Claude), é possível habilitar um ajuste que mantém o computador ativo enquanto o app do Gemini estiver aberto, impedindo que ele entre em repouso.

Apple Intelligence hat in macOS 27 Golden Gate unter anderem in Fotos, in den Kurzbefehlen und in Safari Einzug gehalten. Aber auch Image Playground greift nun tiefer in die KI-Kiste als bisher. Neue Optionen finden wir zudem in Notizen, Freeform und in der Wetter-App. Und Spotlight präsentiert seine Suchergebnisse jetzt gefühlt deutlich schneller als bisher.
Image Playground war bisher eher eine Spielwiese, auf der man nette gemalte oder gezeichnete Bilder und Genmojis erstellen konnte. Unter macOS 27 Golden Gate ist das Programm jetzt aber in der Lage, fotorealistische Bilder zu erzeugen oder Fotos fotorealistisch zu verändern.
So gelingt es uns beispielsweise, einen roten VW-Bus in einen blauen VW-Bus umzufärben. Dabei wird nur die Farbe getauscht, der Rest bleibt wie das Original. Und auch das Nummernschild wird auf Aufforderung hin unkenntlich gemacht. In einem anderen Foto ersetzt Image Playground die Kopfhaare des Autors durch eine Glatze, verlängert den Bart und färbt ihn schwarz. Dass es sich dabei um eine KI-Bearbeitung handelt, ist, zumindest auf den ersten Blick, nicht zu erkennen.
Die Aufforderung, ein fotorealistisches Bild der Golden Gate Bridge und der Elbphilharmonie in Hamburg zu erstellen, führt ebenfalls zum Erfolg. Bei der Brücke ist zuerst nur der linke Pfeiler zu sehen. Auf Aufforderung hin generiert Image Playground dann ein Bild mit der kompletten Brücke. Die App fügt einem Foto mit Meerblick ein Segelschiff hinzu und setzt dann auch noch die Segel. Und in der letzten Aufgabe erstellt das Programm ein im leicht impressionistischen Stil gehaltenes Bild der Münchner Frauenkirche.
Image Playground erstellt nun auch fotorealistische Bilder und kann Fotos bearbeiten.
Thomas Armbrüster
Was uns auffällt: Image Playground weigert sich, Bilder von realen Personen zu erstellen, auch wenn diese schon seit Längerem oder sehr lange tot sind. Eine Zeichnung von Winston Churchill oder Heinrich VIII. können wir darum nicht erzeugen. Und auch die Aufforderung, ein Bild von Prinz Eisenherz im Stil von Harold R. Foster oder Daisy Duck mit einer Latzhose zu zeichnen, gelingt nicht. Hier scheint eine Bremse zu greifen, um keine Kopien von künstlerischen Werken oder Abbildungen von Personen des öffentlichen Lebens zu erstellen.
Bilder von Personen des öffentlichen Lebens erzeugt Image Playground nicht.

Sowohl in Notizen als auch in Freeform können Sie jetzt zeichnen und dazu das Trackpad oder die Maus verwenden. Das ist zwar nicht so effektiv wie auf einem iPad mit Zeichenstift, das sich dafür natürlich wesentlich besser eignet. Aber für schnelle Skizzen ist das tauglich. In Notizen können Sie zudem digitalisierte Unterschriften erzeugen und einfügen, so wie es bisher schon in Vorschau möglich ist. Dabei greift Notizen auch auf die in Vorschau schon verfügbaren Unterschriften zu.

In der Wetter-App sind die einzelnen Kacheln neu angeordnet worden. Für die Vorhersagen für die nächsten zehn Tage gibt es zudem zwei neue Ansichten: eine für Niederschlag und eine für Wind. Anstatt der Balken für die Minimal- und die Maximaltemperatur sowie für die Bewölkung gibt es dann eine Anzeige der Niederschlagswahrscheinlichkeit und für die Regenmenge beziehungsweise für die Windgeschwindigkeit und die Verteilung über den Tag.

In neuen Systemversionen schneidet Apple auch regelmäßig alte Zöpfe ab. Für macOS 27 Golden Gate trifft das vorrangig auf Macs mit Intel-Prozessor zu, die das neue System nicht mehr unterstützen. Viele der Apps in macOS 27 sind darum auch keine Universal-Anwendungen mehr, sondern enthalten nur noch Code für Apple-Chips. Rosetta 2, mit dessen Hilfe sich noch Apps verwenden lassen, die nur Code für Intel-Chips verwenden, ist zwar noch dabei, wird aber in der nächsten Version von macOS nicht mehr enthalten sein. Dank Rosetta funktioniert der alte Laserdrucker des Autors weiterhin, für den es schon seit Langem keine aktuellen Treiber mehr gibt.
In der Dokumentation für Entwickler weist Apple zwar darauf hin, dass das Framework „DVDPlayback“ im Software Development Kit (SDK) nicht mehr enthalten ist. Den DVD Player von Apple gibt es aber weiterhin als App für Apple-Chips, und auch das schon vor Jahren von Apple ausgemusterte Superdrive funktioniert unter Golden Gate. Alternativ lassen sich DVDs auch mit anderen Apps wie VLC abspielen.
Einen weiteren Hinweis finden wir ebenfalls in Apples Dokumentation: Zukünftige Versionen von macOS werden keine verschlüsselten Medien im Format HFS+ unterstützen. Sofern Sie also beispielsweise noch ältere Backups in diesem Format haben und diese weiterhin benötigen, müssen Sie die Daten auf einem anderen Datenträger mit einem anderen Format sichern. Zudem sollten Sie keine Backups mehr auf Datenträger mit diesem Format sichern.
Algo que não passou despercebido durante a apresentação do iPhone Duo, primeiro smartphone dobrável da Apple, foi a animação ao abrir e fechar o aparelho — uma cortesia da versão adaptada do iOS especialmente para o modelo.
Como quase nada é impossível no mundo dos desenvolvedores, essa animação já foi transportada para o macOS graças ao DuoHinge, que adiciona uma ilusão de ótica interativa de dobra à tela física do seu MacBook.
Ao acessar diretamente o sensor de ângulo da tampa integrado ao Apple Silicon, o DuoHinge projeta sua área de trabalho em tempo real em um plano 3D virtual vertical, aplicando perspectiva realista via raycasting, dispersão gaussiana de vidro em duas passagens e dispersão cromática nas bordas conforme você fecha a tela.

O processamento da área de trabalho ocorre localmente no dispositivo, utilizando a taxa de atualização da tela integrada (até 120Hz em telas compatíveis) por meio do ScreenCaptureKit e shaders Metal personalizados, tudo encapsulado em uma camada transparente que permite cliques através dela, sem interromper seu fluxo de trabalho.
O aplicativo lê o sensor de ângulo da tampa e suaviza o movimento de acordo com a cadência de renderização. Um ícone vetorial do MacBook, no estilo da Apple, gira e espelha o ângulo real da sua tela nas barras de menu do macOS (no modo claro ou escuro).
O DuoHinge é gratuito, não contém assinaturas, nem rastreia quantas vezes você abre o seu MacBook. Ele exige pelo menos o macOS Sonoma 14 e pode ser baixado diretamente pela página no GitHub — ao iniciar o aplicativo pela primeira vez, abra-o na barra de menus e conceda permissão de Gravação de Tela e Áudio do Sistema quando o macOS solicitar.
Salvar uma página da web pode ter diversas finalidades — seja para lembrar de algum detalhe textual ou visual, guardar informações de uma certa data ou apenas manter um registro cronológico de algum endereço. Há vezes, porém, que não dá para depender totalmente de bases de arquivos públicos, seja porque o conteúdo pode ter sido alterado ou não é exibido corretamente, entre outros motivos.
Para evitar possíveis problemas do tipo, vale a pena conferir o WebsiteArchiver, um utilitário para macOS que salva e arquiva páginas da web completas, sendo possível separá-las em pastas e categorias. Segundo o desenvolvedor, uma versão para iPhone/iPad será lançada em breve.
Com ele, as páginas da web são salvas localmente como arquivos HTML — com exportação em .html, .warc, .webarchive, .pdf e Markdown — disponíveis permanentemente e independentes de serviços externos.
O app exibe as páginas salvas de três formas diferentes: a opção “Salvo” mostra a cópia offline, enquanto “Leitor” exibe apenas o texto sem distrações e o modo “Ao vivo” mostra a página atual na web. É possível alternar entre eles quando quiser.
Além disso, a captura usa um motor que possibilita que páginas cheias de JavaScript sejam registradas exatamente como aparecem na tela. Também é possível remover imagens inteiras de páginas.
O WebsiteArchiver está disponível gratuitamente na Mac App Store, sendo possível salvar até dez páginas sem custo. Para desbloquear a versão completa, sem limites de registros, é necessário obter a licença vitalícia, disponível por R$120.
Leitores do MacMagazine, porém, podem aproveitar uma oferta especial para adquirir a versão completa diretamente pelo site do WebsiteArchiver: basta digitar MACMAGAZINE30 na área de código promocional para obter 30% de desconto! Saiba, porém, que o cupom é válido somente para os 50 primeiros usos.
O AppZapper, popular desinstalador que oferece uma maneira rápida de excluir aplicativos e seus arquivos associados do macOS, foi reformulado após anos e ganhou um novo design, funcionalidades atualizadas, além de um novo nome: AppZapper 3000.
Lançado originalmente em 2006, o AppZapper 3000 chega justamente no seu 20º aniversário. Entre as novidades, a versão atualizada do aplicativo foi adaptada aos requisitos de segurança do macOS e é mais eficiente na localização de arquivos relacionados aos softwares que serão apagados.
Posts relacionados
O funcionamento do app é um show à parte: após a instalação, basta arrastar e soltar um aplicativo no AppZapper e clicar no botão “Zap All” para remover o aplicativo e os arquivos relacionados, acompanhado de uma animação de arma a laser e efeitos sonoros. Ele localiza e exclui todos os arquivos de um aplicativo em poucos segundos, e os usuários podem escolher entre quatro temas diferentes.
O software pode ser baixado gratuitamente, sendo possível realizar três “zapeadas” gratuitas. A licença custa US$18 para um único usuário e US$29 para um pacote familiar, que permite o uso do aplicativo em até cinco Macs. Há, ainda, um plano corporativo que permite o uso em até 25 Macs, o qual está disponível por US$99.

Mac users are faced with the annual classic computing question again; should I upgrade to the latest major new system software that is available? In this case, MacOS 27 Golden Gate is available to download and widely considered to be a solid system software version, so if your Mac is currently running MacOS Tahoe 26, ... Read More
The post Should You Update to MacOS 27 Golden Gate from MacOS Tahoe or Sequoia? appeared first on OS X Daily.
Die Entwickler von Webkit listen auf ihrer Webseite 58 neue Funktionen sowie 525 Verbesserungen und Fehlerkorrekturen in der Rendering-Engine von Safari auf. Das betrifft natürlich vor allem Web-Entwickler. Wobei Anwender von weniger Fehlern und einer größeren Kompatibilität zu Webstandards natürlich ebenfalls etwas haben. Sämtliche Änderungen gelten sowohl für macOS 27 als auch für iOS 27 und iPadOS 27.
Um vier Funktionen erweitert Apple Intelligence Safari 27: eine Option, die geöffnete Tabs automatisch nach Zusammengehörigkeit gruppiert, Mitteilungen, wenn sich der Inhalt einer Webseite ändert, sowie die Möglichkeit, Erweiterungen für eine Webseite zu erstellen.
Die vierte Neuerung betrifft die Zusammenarbeit von Safari mit der App „Passwörter“. Diese ermöglicht es, in der App die als schwach oder mehrfach verwendet gelisteten Passwörter auf den betreffenden Webseiten automatisch von Safari ändern zu lassen. Noch können Sie das nicht ausprobieren, denn diese Funktion werden iOS 27 und macOS 27 erst mit einem späteren Update bekommen.
Die automatische Gruppierung von geöffneten Tabs nach Themen schalten Sie in den Einstellungen von Safari unter „Tabs“ ein. In der Seitenleiste werden die Tabs dann unter einem Obergriff untergeordnet und Sie können diese dort ein- oder ausblenden. In iOS und iPadOS finden Sie die Einstellung in der Tab-Ansicht hinter dem runden Symbol mit den drei horizontalen Linien in der oberen linken Ecke.
Suchen wir beispielsweise nach „Macbook Neo“ und öffnen nacheinander einzelne Links in einem neuen Tab, werden alle mit einer Ausnahme zuverlässig gruppiert. Auch bei der Suche nach „Schwarze Löcher“ fasst Safari die dann geöffneten Tabs unter dem Thema in der Seitenleiste zu einer Gruppe zusammen. Auf dem iPhone fehlt die Seitenleiste; stattdessen werden die Tabs in der App-Ansicht in separate „Boxen“ sortiert.
Eine weitere neue Option sind Mitteilungen von Safari, wenn sich der Inhalt einer Webseite ändert. Die Mitteilungen aktivieren Sie für eine Webseite, indem Sie im Adressfeld auf die drei horizontalen Striche klicken. Es lassen sich stündliche, tägliche, wöchentliche oder monatliche Änderungen einstellen. Die betreffende Webseite muss für die Benachrichtigung nicht in einem Tab geöffnet sein. Klicken Sie die Mitteilung dann in der Mitteilungszentrale an, öffnet sich die Seite. Dort können Sie dann auch wählen, ob die Überwachung fortgesetzt oder beendet werden soll.
Thomas Armbrüster
Über dasselbe Symbol im Adressfeld können Sie auch eine Safari-Erweiterung von Apple Intelligence erstellen lassen, für die es eine Reihe von Vorschlägen gibt. Sofern für eine Funktion Apps im App Store verfügbar sind, werden diese eingeblendet und Sie können sie kaufen und installieren. Andernfalls wird eine Erweiterung in Safari generiert.
Wir lassen eine der vorgeschlagenen Erweiterungen erstellen, die in ihrem Symbol in der Symbolleiste die geschätzte Lesedauer in Minuten mit einer Zahl einblendet. Eine andere kopiert den auf der Webseite markierten Text zusammen mit der URL in die Zwischenablage. Ist nichts markiert, werden der Titel der Seite und die URL kopiert.
Die neuen Optionen von Apple Intelligence in Safari 27 finden wir hilfreich. Von den Fehlerkorrekturen und Verbesserungen in Webkit werden zudem nicht nur Entwickler, sondern auch alle Anwender profitieren. Etwas vermissen wir aber weiterhin in Safari 27: mehr Auswahl bei den Suchmaschinen. Hier bleibt es wie bisher bei der Liste mit fünf Anbietern und ohne Möglichkeit, diese Liste zu erweitern.

Just as I was heading into the final stretch of review season, TestFlight was updated to reverse an update I wrote about in July. That update added search, which was one of my longstanding wishes for TestFlight. However, for some users, the update also changed the sorting of betas from reverse chronological order to alphabetical, including active betas alongside expired ones. As someone who reviews a lot of apps, that made TestFlight barely usable.
With the latest update, I’m happy to report that the sorting order has been restored to reverse chronological order. The most recently updated betas appear at the top of the list, and when you want to find something older, search is a great option. Returning to reverse chronological order may seem like a small thing, but it’s made a world of difference in keeping up with the apps I test.
Search was near the top of my list of TestFlight wishes for years, and its addition made a meaningful difference to the app’s usability. But I’ve had a lot of TestFlight wishes over the years that are scattered across multiple articles, so I thought I’d share what else I’d like Apple to tackle with TestFlight:
The bottom line is that while TestFlight is once again usable, it could be much better. I recognize that TestFlight isn’t an app used by most people, but like Apple’s own OS beta testing program, TestFlight betas are an important part of developers’ workflow. They provide QA feedback and a promotional channel that the friction encountered by TestFlight users undermines.
I’m glad TestFlight continues to get meaningful updates. I just hope it gets more attention going forward.
Since the debut of Mac OS X in 2001, Apple has released dozens of versions of its Mac operating system, introducing new features, design updates, performance improvements, and more. From early big-cat releases such as Panther and Leopard to more recent California-inspired versions like Sonoma, Sequoia, Tahoe and Golden Gate, each release marked a new chapter in the Mac’s evolution.
Whether you’re trying to identify the version running on your Mac, check compatibility before upgrading, or find out which releases are still supported, this guide covers every Mac OS X and macOS version in chronological order – from the original Mac OS X Cheetah to macOS 27 Golden Gate.
Discover the major features introduced with each release, including Spotlight in Tiger, Time Machine in Leopard, Siri in Sierra and and the enhanced Spotlight search introduced in macOS 27 Golden Gate.
Below, you’ll find a complete list of macOS versions in order, along with release dates, codenames, key details and support information.
The latest version of macOS is macOS 27 Golden Gate, released on September 14, 2026. Apple is expected to update Golden Gate throughout 2026 and 2027, beginning with macOS 27.1.
For details of the latest macOS 27 release, new features, beta updates and compatibility, see our complete macOS 27 Golden Gate Guide.
macOS is Apple’s operating system for the Mac, in the same way iOS runs on the iPhone and iPadOS runs on the iPad. It provides the user interface and acts as the link between a Mac’s hardware and its software.
All Macs have run macOS – formerly known as Mac OS X – since its debut in 2001. Before that, Apple computers used Mac OS 9. macOS is based on Unix technology developed at NeXT, the company Steve Jobs founded before returning to Apple.
Since its launch on March 24, 2001, macOS has evolved significantly, gaining tighter integration with iOS devices, cloud services, and productivity features such as Time Machine, Quick Look, Exposé, Spaces, and Desktop Stacks.
Below is a complete overview of macOS versions, showing how Apple’s desktop operating system has developed over time, along with the official names and internal codenames used for each release.
Foundry
OS X 10 beta: Released in September 13, 2000, this preview version of OS X was codenamed Kodiak. It was based on technology from NeXT Computer, which was another company founded by Apple founder Steve Jobs and it introduced the Aqua user interface as well as protected memory and preemptive multitasking to stop crashes. This beta cost $29.95.
OS X 10.0: Code named Cheetah, this was the first major release of Mac OS X, arriving on March 14, 2001. It was Apple’s first OS built on a Unix-based foundation. Unfortunately it was slow and rough around the edges.
OS X 10.1: Just a few months ofter the first version of Mac OS X launched, Apple introduced the Puma update on September 15, 2001. This time is was stable and ready for everyday use, hardware support was better, and other issues with the fist version were addressed.
OS X 10.2: Jaguar arrived on August 14, 2002, significantly improving performance and usability, introducing Quartz Extreme for smoother graphics, a faster Finder, and better networking. iChat was one of the new features.
OS X 10.3: In October 2003 Apple introduced Panther which focused on speed, stability, and polish, delivering noticeably faster performance and a more responsive system. New features included: Exposé for managing windows, Fast User Switching, and FileVault disk encryption. Safari arrived as the default web browser.
OS X 10.4: Tiger arrived in April 2005 with new features like Spotlight search and Dashboard widgets.
OS X 10.5: In October 2007 Leopard arrived and added features like Time Machine for automated backups, Spaces for virtual desktops, and a redesigned Finder with Cover Flow. Time Machine also arrived as a simple way to back up a Mac.
OS X 10.6: Released in 2009, Snow Leopard focused on performance, stability, and efficiency rather than flashy new features.
OS X 10.7 Lion: Arriving in July 2011, Lion brought iPad-inspired features to the Mac, like Launchpad, full-screen apps, and multi-touch gestures. It also introduced system-wide Auto Save, Resume, and Versions so that users didn’t need to worry about manual saving.
OS X 10.8: A year later, in 2012 Mountain Lion brought more iOS features to the Mac including Messages, Reminders, Notes, Notification Center, and iCloud integration. Gatekeeper security was also emphasised.
Foundry
OS X 10.9: In October 2013 Apple stopped naming Mac OS X versions after big cats and switched to Californian landmarks, starting with Mavericks. It introduced features like Finder Tabs, Tags, and memory compression, making Macs faster and more responsive. It was also the first time Apple offered the Max OS X update for free.
OS X 10.10: Introduced in October 2014, Yosemite brought a major visual redesign with a cleaner, flatter interface, translucent elements, and a more modern look inspired by iOS (iOS 7 with its big redesign had been introduced in 2013). Continuity features from the iPhone and iPad included Handoff, iCloud Drive, and the ability to make and receive calls and texts from a Mac.
OS X 10.11: El Capitan arrived in September 2015 and, like Snow Leopard in 2007, focused more on refinement and stability. It brought improvements like better window management (Split View), smoother graphics, and performance boosts.
macOS 10.12: In September 2016 macOS Sierra was the first version to be referred to as macOS rather than Mac OS X, better aligning it with iOS, watchOS and tvOS. It brought Siri to the Mac and improved integration with iPhone and iPad with features like Universal Clipboard.
macOS 10.13: This was another update where the focus was on performance rather than flashy new features. High Sierra in September 2017 brought updates to core apps like Photos and Safari but mostly focused on security and efficiency updates.
macOS 10.14: In September 2018, Mojave introduced a system-wide Dark Mode and introduced Desktop Stacks for better file organization.
Foundry
macOS 10.15: Arriving in October 2019, Catalina replaced iTunes with separate Music, TV, and Podcasts apps and introduced Sidecar so an iPad could be used as a second display for a Mac. It also ended support for 32-bit apps.
macOS 11: Big Sur was the first version to drop the ten, from Mac OS X, and start again at 11. Launched in November 2020 it was a major redesign of Apple’s Mac operating system, with a cleaner, more modern interface, updated icons, a refined Control Center, and closer visual alignment with iOS.
macOS 12: Arriving in October 2021, Monterey introduced Universal Control (one mouse/keyboard across Mac and iPad) and improved FaceTime.
macOS 13: macOS Ventura arrived in October 2022 and introduced Stage Manager for better multitasking, improved Continuity features (including using an iPhone as a webcam, and brought major updates to Mail, Safari, and Spotlight. Read: How Ventura and Monterey compare.
macOS 14: In September 2023 Sonoma made the desktop more immersive with animated wallpapers and desktop widgets you can interact with. There were game-focused improvements in Game Mode and video conferencing features like Presenter Overlay were added. Here’s how Sonoma compares to Ventura.
macOS 15: A year later in September 2024, Sequoia brought iPhone Mirroring and added Apple Intelligence features. Here’s how Sequoia compares to Sonoma.
macOS 26: Tahoe arrived in September 2025 with a bold new Liquid Glass design with transparent, customizable interface elements and tighter integration with iPhone and iPad. As with iPhone and iPad, Apple unified version numbering, so the macOS jumped from macOS 15 to 26. Apple also expanded Apple Intelligence, improved Spotlight, improved the Phone related features, and added a new Games app. This was the final macOS version to support Intel-based Macs. See how macOS 26 Tahoe compares to macOS 15 Sequoia.
macOS 27: macOS 27 Golden Gate was released on September 14, 2026, bringing Siri AI, Visual Intelligence, enhanced Spotlight search, performance improvements, and refinements to the Liquid Glass interface introduced with macOS Tahoe. Golden Gate is also the first major macOS release to require Apple silicon, ending support for Intel-powered Macs. See how macOS 27 Golden Gate compares to macOS 26 Tahoe.
Here’s an overview of every version of macOS and Mac OS X Apple has released. You’ll find a complete list of each version of OS X and macOS, along version code names, internal code names (if available) and the most recent version and when it was released.
macOS Tahoe.

Apple provides regular feature and security updates for the current version of macOS and generally continues to issue security updates for the previous two major versions.
As of September 2026, macOS 27 Golden Gate is the current version. Apple also released security updates for macOS 26 Tahoe and macOS 15 Sequoia alongside Golden Gate on September 14, 2026.
With the arrival of Golden Gate, macOS Sonoma appears to have dropped out of Apple’s regular support cycle, with its most recent update released in August 2026.
Occasionally Apple releases updates for much older versions of macOS to address specific problems. For example, in February 2026 it issued updates for Big Sur and Catalina to address a certificate issue affecting FaceTime and Messages.
See: How long do Macs and MacBooks last? We also have a full list of which Macs run which versions of macOS here.
As you can see from the list above, with the exception of the first OS X beta, all versions of the Mac operating system from 2001 to 2012 were named after big cats, from Cheetah to Panther to the final release, Mountain Lion. But while the public-facing builds were named after big cats, internally, they were named after wines (aside from OS X 10.6 which had no codename).
Even after Apple switched public-facing code names to places in California back in 2013, it carried on naming them after wines internally until 2014. In 2015, Apple decided to change the theme of internal code names from wines to types of apples.
In 2016, Apple took the plunge to unify the branding of its operating systems by rebranding Mac OS X to macOS, which sits nicely alongside iOS, tvOS, and watchOS and paved the way for macOS 11, the successor to Mac OS X, which arrived twenty years after the first beta of Mac OS X.
In 2025, Apple decided to sync up the numbering system between all its operating systems, moving from macOS 14 to macOS 26 to better reflect the year. macOS 26 Tahoe lived most its lifetime as the most recent version in the year 2026 before being replaced with macOS 27 in September 2026.
You can tell which version of macOS you are running by clicking on the Apple logo in the top left and choosing About This Mac.

Kurzbefehle zu erstellen, war bisher Handarbeit. Sie mussten die einzelnen Schritte selbst heraussuchen und zusammenfügen. Bei komplexeren Aufgaben war das aber zum einen mühsam und zum anderen fehleranfällig. In macOS 27 Golden Gate können Sie nun mit eigenen Worten beschreiben, was ein Kurzbefehl für Sie erledigen soll.
Und das funktioniert auch mit Deutsch. Da es die App Kurzbefehle auch auf dem iPhone und dem iPad gibt, können Sie dort unter iOS 27 und iPad 27 ebenfalls Apple Intelligence in der App verwenden.
Mit Kurzbefehlen lassen sich viele Dinge erledigen. Sie können unter anderem Informationen über den Mac abrufen, Einstellungen vornehmen, E-Mails oder Nachrichten versenden, Kalenderereignisse auflisten lassen oder Informationen von Webseiten abrufen.
Zudem lassen sich mehrere Aktionen miteinander verknüpfen oder Kurzbefehle zu einem bestimmten Zeitpunkt ausführen, wie zu einer bestimmten Uhrzeit, wenn eine Nachricht von einer bestimmten Person eintrifft oder wenn Sie einen Fokus auswählen. Am besten schauen Sie sich die lange Liste der verfügbaren Aktionen an und überlegen, welche Sie davon eventuell sinnvoll einsetzen könnten. Oder Sie probieren es einfach aus, indem Sie eintippen, was der Kurzbefehl erledigen soll.
Die Liste der verfügbaren Aktionen ist sehr lang, oft gelangen Sie mit einer Beschreibung schneller ans Ziel.
Thomas Armbrüster
An eine Grenze stoßen die Kurzbefehle im Test, wenn Sie direkt auf Inhalte von Dokumenten zugreifen wollen. So können Kurzbefehle etwa den Text in einem geöffneten Textedit-Dokument nicht direkt erkennen. Sondern Sie müssen den Text zuerst markieren oder in die Zwischenablage kopieren, um ihn anschließend weiterzuverarbeiten. Auch lässt sich ein in die Zwischenablage kopierter Text nicht direkt in ein neues Pages-Dokument einfügen.
Sobald Sie einen neuen Kurzbefehl anlegen, startet Apple Intelligence mit einer Animation und einem Eingabefeld. In diesem tippen Sie mit eigenen Worten ein, was der Kurzbefehl erledigen soll. Es können auch Aufgaben sein, deren Aktionen miteinander verknüpft sind. Apple Intelligence sucht nun nach den passenden Aktionen und erstellt den Kurzbefehl.
Beschreiben Sie einfach, was ein Kurzbefehl für Sie erledigen soll.
Thomas Armbrüster
Lässt sich die Aufgabe nicht erledigen, weil es keine passenden Aktionen gibt, bekommen Sie in der Regel eine Rückmeldung und manchmal auch einen Vorschlag, was alternativ möglich wäre. Zudem können Sie einen Kurzbefehl nachträglich ändern oder ergänzen, indem Sie in das Eingabefeld „Änderungen beschreiben” eintippen, was geändert werden soll.
Einen Kurzbefehl können Sie nachträglich ändern und beispielsweise neue Aufgaben hinzufügen.
Thomas Armbrüster
Eine einfache Aufgabe gab es zum Anfang: Die Systemeinstellung „Startvolume” direkt öffnen. Da wir verschiedene Volumes mit unterschiedlichen Systemversionen auf dem Mac verwenden, ist das wesentlich schneller, als manuell die Systemeinstellungen zu öffnen und dort ein anderes Volume auszuwählen. Um schnell darauf zugreifen zu können, haben wir den Kurzbefehl der Menüleiste hinzugefügt.
Ferner haben wir einen Kurzbefehl erstellt, der die Anzahl der Zeichen des in Textedit markierten Textes anzeigt, da die App keine entsprechende Funktion hat. Auch auf diesen Befehl greifen wir dann über die Menüleiste zu.
Mithilfe eines Kurzbefehls lassen sich die Zeichen im markierten Text von Textedit zählen.
Thomas Armbrüster
Ein weiterer Kurzbefehl listet die aktuell an diesem Tag neu auf der Macwelt-Webseite veröffentlichten Artikel auf. Das funktioniert sogar, wenn Safari nicht gestartet ist. Diese Aktion verwendet die RSS-Funktion der Webseite. Und ein anderer Kurzbefehl erstellt eine Liste der aktuellen Sendungen in der App Podcasts.
Mithilfe eines Kurzbefehls lassen wir uns die aktuellen Artikel auf macwelt.de und die aktuellen Podcasts auflisten.
Thomas Armbrüster
Anschließend haben wir einen Kurzbefehl erstellen lassen, der nur den Haupttext einer Webseite kopiert und als Textdatei sichert. Apple Intelligence greift dazu auf die Reader-Funktion von Safari zu und kopiert nur diesen Text. Befindet sich dann ein fremdsprachiger Text in der Zwischenablage, lässt er sich mithilfe eines anderen Kurzbefehls ins Deutsche übersetzen und wieder in die Zwischenablage kopieren.
Der letzte von uns erstellte Kurzbefehl startet, wenn sich der Mac mit dem WLAN verbindet, und öffnet Mail, Nachrichten und Safari. In Safari wird dabei auch gleich die Webseite der Macwelt geöffnet.
Kurzbefehle können automatisch starten, wenn ein bestimmtes Ereignis stattfindet.
Thomas Armbrüster
Durch die Möglichkeit, Kurzbefehle mithilfe von Apple Intelligence in eigener Sprache zu beschreiben, lassen sich Aktionen wesentlich einfacher erstellen als bisher. Zudem können Sie nun etwas bequem ausprobieren, um zu sehen, ob es funktioniert oder nicht. Und die Liste der verfügbaren Aktionen hat sich nach einer ersten Durchsicht gegenüber der Vorgängerversion der Kurzbefehle unter macOS Tahoe erweitert.
