Port permite jogar The Legend of Zelda: Tears of the Kingdom no Mac em resolução 1440p e a 90fps
The Legend of Zelda: Tears of the Kingdom, um dos jogos para Nintendo Switch e Nintendo Switch 2 mais populares e aclamados dos últimos anos, ganhou uma versão recompilada que pode ser rodada nativamente em Macs com Apple Silicon.
Mais um fruto do projeto MacNativeGames, o port roda em resolução 1440p e com ótimo desempenho no macOS, chegando a 90 quadros por segundo.
A versão usa a API 1Application programming interface, ou interface de programação de aplicações. Metal 4 da Apple e o MetalFX — tecnologias que minimizam os engasgos e deixam a jogatina mais fluida. Apesar disso, segundo o Notebookcheck, explorar novas áreas do mundo aberto de Hyrule pode causar travamentos momentâneos.

O grande desafio é o processo de configuração do jogo, já que os próprios usuários precisam fornecer uma ROM dele nos formatos XCI ou NSP — além de rodar uma série de comandos usando as ferramentas de desenvolvimento Xcode.
Esse processo de instalação trabalhoso do port, cujos arquivos podem ser baixados gratuitamente do GitHub, existe para evitar possíveis problemas com a Nintendo envolvendo direitos autorais — que, como sabemos, é bem chatinha nesse quesito.

Latest macOS beta: What’s new and should you install it?
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.
What’s the latest macOS beta?
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.
macOS 27 Golden Gate beta version tracker
- Apple released macOS 27.2 Golden Gate Developer Beta on September 16, 2026.
- The macOS 27.2 Golden Gate Public Beta should be released sometime the same week; new versions are usually released a day or two after the new developer beta.
macOS 26 Tahoe beta: Apple may continue updating macOS 26 Tahoe with security and maintenance releases, but macOS 27 is now the current operating system and the focus of Apple’s beta program.

What’s new in the latest beta?

New features in macOS 27.
Foundry
Apple has not announced any major consumer-facing additions in macOS 27.2 beta 1. The following changes are expected though:
- Bug fixes and performance improvements: Addressing issues in the first release of macOS 27.
- Additional Siri AI languages: Apple has said the Siri AI will expand to French, Japanese, Korean, Portuguese and Spanish in October.
- Automatic password changes: The promised feature that automatically changes compromised passwords has not yet been implemented, but it could arrive in macOS 27.2..
- Notify Me in Safari: The Safari feature that monitors webpages may arrive in the beta of macOS 27.2.
We’ll update this section as changes are discovered.
See Apple’s developer website for more information about the beta.
Should you install the macOS beta?

Apple
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…
- You need to test apps
- You want early access to new features
- You have a secondary Mac available
Wait if…
- This is your primary work machine
- You rely on niche or specialist software
- Stability is critical to your workflow
| 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 |
What are the risks of installing beta software?
Installing pre-release software on a primary device carries several risks.
- System instability: Performance problems, freezes, crashes, and other unexpected behavior are common during beta testing.
- App failures: Third-party applications may crash, behave unpredictably, or stop working entirely.
- Hardware strain: Early beta builds can increase battery drain and cause Macs to run hotter than usual.
- Data loss: Software bugs may corrupt files, and downgrading to a stable version often requires a complete system reset.
Safety precautions and best practices
If you decide to install the beta, take the following precautions:
- Use a secondary device: Avoid installing beta software on your primary Mac or on any machine used for critical work.
- Create a full backup: Use Time Machine to create a complete backup before upgrading so you can restore your Mac if something goes wrong. Note that this needs to be a Time Machine backup from before the beta was installed and you will lose anything saved subsequently.
- Install on a separate volume: Consider installing the beta on a separate volume or external SSD rather than replacing your main operating system.
- Check storage space: Make sure you have at least 15GB of free storage available before beginning the installation.
How to install the macOS beta

Foundry
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:
- Back up your Mac: Before installing any pre-release software, it is critical to prepare your Mac to avoid data loss. Beta software is inherently unstable and can cause crashes or app compatibility issues.
- Register your account either as a public beta tester or as a developer in order to enable beta updates on your Mac:
For the Public Beta: Visit the Apple Beta Software Program website, sign in with your Apple ID, and agree to the terms.
For the Developer Beta: Register as an Apple Developer on Apple’s website, download the Apple Developer app from the App Store, sign in with your standard Apple ID, and complete the free registration process. - On the Mac where you wish to install the beta, open System Settings and navigate to General > Software Update.
- Click the (i) info button next to Beta Updates.
- Enable Beta Updates.
- The beta will appear as an available upgrade. Select the macOS beta you want to install (e.g., macOS Public Beta or Developer Beta).
- Click Upgrade Now to begin the download and installation.
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.
How to get a free Apple developer account
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:
- Get the Apple Developer App from the App Store.
- Open the app on your iPhone.
- Tap on Account.
- Tap on Sign In.
- Sign in using your usual Apple ID.
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.
FAQ
Who can run the macOS beta?
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.
macOS public beta vs developer 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.
Is the macOS beta stable?
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 recommend installing it on a partition, which these days is really a volume (and is much easier to create than a partition was). Read about how to do that here: How to dual-boot Mac: Run two versions of macOS on a Mac.
- Alternatively, you could install the macOS beta on an external drive and run it on that.
We discuss the safety of the macOS beta and the risks you might be taking in more detail in a separate article.
How to prepare your Mac for the beta
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.
How to send feedback to Apple
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.
Will I be able to update from macOS beta to the final version?
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.
Can I talk about the beta publicly?
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.
How to downgrade from the macOS beta
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.
Is the beta free to download?
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.
Can I go back to the stable version?
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.
Should I install the beta on my main Mac?
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.
Do I need an Apple Developer account to install the beta?
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.
How often are new beta versions released?
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.
Is the macOS beta safe to install?
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.
Will my apps work with the macOS beta?
Many apps will work normally, but some third-party software may crash, perform poorly, or not launch at all until developers release updates.

macOS 27 Golden Gate: The Ars Technica review
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.

How to downgrade macOS 27: Roll back Golden Gate to Tahoe
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.
Can I downgrade from macOS Golden Gate to Tahoe?
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:
- A backup: You will have to wipe your Mac, so you need to have a backup of your data.
- The correct macOS version: You need to download the full installer for the version of macOS you want to install.
- An external drive: You need to create a bootable installer of macOS. Apple says a 32GB USB drive has more than enough space for any macOS installer; 16GB is sufficient for most older versions.
- A reliable internet connection: The installer may need to download firmware and other information specific to your Mac.
Follow these steps, which we explain in more detail below:
- Back up your Mac.
- Check that your Mac can run macOS Tahoe.
- Get the Tahoe installer.
- Create a bootable installer.
- Shut down your Mac and start it from the bootable installer.
- Erase the internal startup volume using Disk Utility.
- Install macOS Tahoe.
- Set up the Mac and recover compatible files from your backup.
Can I downgrade macOS 27.1 to iOS 27.0 (or macOS 26.7 to 26.6)?

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.
Downgrading macOS to an earlier version: Step-by-step guide
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.
Before you begin: Back up your Mac
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:
- Manual file copying: Copy your most important files, folders, photos, and music to an external storage drive.
- Third-party backup software: Tools for backing up a Mac, such as ChronoSync, Get Backup Pro, SuperDuper, or Carbon Copy Cloner can create a separate copy of your data. Do not assume that a clone created under Golden Gate will be bootable on your Mac or that it can replace the Tahoe installer.
- Cloud synchronization: Make sure cloud storage services such as iCloud, Dropbox, OneDrive, or Google Drive have finished synchronizing. Do not assume that every app’s data is stored in the cloud, as some applications store data only locally.
- Time Machine: If you have a Time Machine backup from before you upgraded to Golden Gate, you can use it to transfer compatible data after reinstalling Tahoe.

Check that your Mac can run Tahoe

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.
Get the macOS Tahoe installer

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
- Open the Tahoe download link on a compatible Mac. If the Mac App Store does not open, close it if it is already running and try the link again in Safari.
- Click Get.
- Software Update should open and offer to download Tahoe. Click Download and confirm that you want to download the older operating system.
- If the installer opens automatically after downloading, quit it. You do not want to run it directly over Golden Gate.
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.
Create a bootable Tahoe installer

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.
Start your Mac from the bootable installer

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.
- Shut down the Mac.
- Connect the bootable Tahoe installer directly to the Mac.
- Press and hold the power button. Continue holding it until the startup options screen appears.
- Select the bootable installer, then click Continue.
- Connect to Wi-Fi if prompted.
Erase the internal startup volume

Foundry
Warning: This step will permanently remove the local accounts, applications, settings and files stored on the Mac.
- When the Utilities window appears, select Disk Utility and click Continue.
- In Disk Utility, choose View > Show All Devices if the internal volumes are not visible.
- Select the internal macOS startup volume, usually named Macintosh HD.
- Click Erase or Erase Volume Group, as offered.
- Use Macintosh HD as the name and APFS as the format.
- Confirm the erase and wait for it to finish.
- Quit Disk Utility to return to the Utilities window.
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.
Install macOS 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.
- In the Utilities window, select Install macOS Tahoe and click Continue.
- Follow the onscreen instructions.
- When asked to choose a destination, select the newly erased internal volume, normally Macintosh HD.
- Keep the Mac connected to power and the internet while installation completes. It may restart several times.
Set up your Mac

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.
Transfer data from your Time Machine backup

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:
- Connect the Time Machine backup disk.
- Open Migration Assistant from the Utilities folder in Applications.
- Choose to transfer information From a Mac, Time Machine backup, or startup disk.
- Select the Time Machine disk and then the appropriate backup.
- Choose the categories you want to transfer and click Continue.
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.
What to do if the older macOS won’t install
Check the following:
- Confirm that the Mac model supports the version you are installing.
- Confirm that the full installer is in the Applications folder and is named correctly before creating the USB installer.
- Connect the installer directly rather than through a hub or dock.
- Make sure the Mac is connected to the internet.
- Re-create the installer if Terminal says it is invalid or the installation fails repeatedly.
- Confirm that the internal startup volume was erased as APFS.
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.
Tips to avoid problems and data loss when you downgrade macOS
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.
Take screenshots of preferences and settings
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.
Synchronize cloud services
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.
Downgrading an older Intel Mac
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:
- Shift-Option-Command-R to offer the macOS that came with the Mac, or the closest version still available.
- Option-Command-R to offer the latest macOS compatible with the Mac.
- Command-R to reinstall the current version.
Internet Recovery cannot install a version older than the one the Mac supports, and the exact version offered can vary.

Das bewirkt Apple Intelligence in Fotos unter macOS 27 Golden Gate
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.
Apple Intelligence
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.

Fotos besser bereinigen
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.


Bildausschnitt erweitern
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.


Perspektive ändern
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.


Fazit
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.

Como impedir que o Mac entre em repouso ao usar o Gemini
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.
Veja como fazer isso! 👨💻

macOS 27 Golden Gate – bessere Apps dank Apple Intelligence
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.
Fotorealistische Bilder
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.

Zeichnen in Notizen und Freeform
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 Notizen gibt es jetzt ein Zeichenwerkzeug sowie die Möglichkeit, digitale Unterschriften zu erzeugen und zu verwenden.
Thomas Armbrüster
Noch zwei weitere Neuerungen hat Freeform aufzuweisen. Die Boards lassen sich jetzt in Ordnern ablegen, die Sie über ein neues Symbol in der Seitenleiste anlegen. Und wenn Sie den dunklen Modus einschalten, passt sich Freeform nun daran an. Auch die Zeichenfläche wird dunkel.

In Freeform lassen sich die Boards jetzt in Ordnern ablegen und die App unterstützt zudem den dunklen Modus.
Thomas Armbrüster
Übersichtlicheres Wetter
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 der Wetter-App sind die Kacheln neu angeordnet worden und es gibt separate 10-Tages-Vorhersagen für Niederschlag und Wind.

Was es bald nicht mehr gibt
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.

DuoHinge leva a animação de dobra do iPhone Duo para os MacBooks
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.
An iPhone Duo–style hinge animation, but on a MacBook. Sometimes it’s fun to build things just because. pic.twitter.com/grYKra4X91

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.


WebsiteArchiver é um utilitário para macOS que salva páginas da web com praticidade
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.
