NOTE: I hate website ads, but this one small Google ad below helps me with the cost of running Mr. Macintosh.com. Thank you!
1. OCLP for Unsupported Macs Warning
OpenCore Legacy Patcher is not compatible with macOS Golden Gate and macOS Tahoe. Make sure you go into System Settings > Software Update and TURN OFF Download Updates&Install macOS Updates.
If you use OCLP on an unsupported Mac, wait for official OpenCore Legacy Patcher 3.0.0 testing and compatibility information before attempting to install.
2. Should You Install macOS Golden Gate Beta?
Most users should not install macOS Golden Gate Beta on their main Mac. This is early beta software, which means apps may crash, battery life may be reduced, accessories may not work correctly, and some features may be unfinished.
Install it only if you have a test Mac, a full backup, and a reason to test the new release early. I recommend two types of backups: Time Machine & A direct copy of your important files and apps
This might seem like a lot, but TRUST ME, it will be worth it if something goes wrong!
MacAdmins, developers, and advanced users can begin testing app compatibility, MDM enrollment, security tools, VPN clients, printers, FileVault workflows, software update behavior, and deployment processes.

Apple today provided developers with the fifth beta of macOS Golden Gate, with the update coming two weeks after Apple seeded the fourth beta.
Developers can download macOS Golden Gate by going to System Settings > General > Software Update. Beta Updates will need to be enabled, and a free developer account is required.
macOS Golden Gate includes multiple design improvements. Liquid Glass opacity has been improved to increase readability, there's a slider for controlling the level of transparency, and changes to shadowing make it easier to tell when a window is active. Apps now have uniform toolbars, edge-to-edge sidebars, and less rounded corners, plus there are fewer icons in menu bars.
Siri has been transformed into Siri AI, a chatbot-style assistant that combines general world knowledge, your personal data, and onscreen awareness to answer questions about anything and find information for you. Siri lives in Spotlight, and you can ask questions with the new Search or Ask interface.
There's also a Siri app where you can chat with Siri and view past conversations, and on newer Macs, you can set a custom voice for Siri with personalized pace and expressivity. Visual Intelligence is now on the Mac so Siri can answer questions about what's on your screen, and a Write with Siri feature lets Siri generate text or give feedback on your writing.
There are AI photo editing tools in the Photos app, AI tab organization in Safari, an option to use AI to automatically update weak passwords in the Passwords app, and a revamped Image Playground app that can generate photorealistic images.
If you’re curious about testing out MacOS 27 Golden Gate beta but you aren’t ready for the full commitment of installing it as your primary operating system, the simplest and safest way to run MacOS 27 Golden Gate beta is within a virtual machine. While one of our authors dove right into MacOS 27 Golden ... Read More
A nova versão foi compartilhada pelo usuário mactracker na versão beta do macOS 27 e, como apontado por ele, permite exibir sugestões contextuais de respostas inteligentes geradas pela Siri sem a necessidade de inserir automaticamente no rascunho, semelhante ao funcionamento de outras inteligências artificiais (IA) em apps de email.
As opções da nova barra incluem alternativas de edição, reescrita, correções gramaticais e/ou de escrita e uma opção intitulada “How does this sound?”, além das ferramentas tradicionais de formatação, escanteadas na lateral direita do novo layout.
Na versão atual, essas opções de formatação de texto também estão recolhidas na lateral direita da janela do aplicativo, desaparecendo por completo assim que se seleciona a opção de escrever com a Siri.
O novo layout está oculto por trás de uma feature flag interna, de forma que a maioria dos usuários da versão beta não consegue habilitá-lo. A beta 4 apresenta ainda algumas inconsistências no funcionamento do recurso, como a ausência da barra na escrita de novas mensagens, restringindo o seu funcionamento às réplicas de email.
Não se sabe ao certo se o recurso chegará à versão final do macOS 27 (prevista para aterrissar em setembro), mas ele parece acompanhar as reformulações propostas sobre a integração das ferramentas de IA no cotidiano do ecossistema da Apple nos sistemas 27.
With the launch of the MacOS 27 Golden Gate public beta program, now even more users can experience MacOS 27 as it’s actively being worked on by Apple. MacOS 27 Golden Gate has a heavy focus on performance improvements, but there’s also refinements other than the Liquid Glass interface look, improvements to Spotlight and Mail ... Read More
For Mac users who are currently running MacOS 27 Golden Gate beta, Apple has released the 4th beta version of MacOS 27 developer beta. The latest beta build is available to download now through Software Update, as an IPSW file, or as the full installer. MacOS 27 Golden Gate has a heavy focus on performance ... Read More
Apple on Monday released the fourth developer betas of iOS 27, iPadOS 27, and macOS Golden Gate (macOS 27), continuing the rapid beta cycle following the company’s announcements at WWDC 2026. The new builds arrive exactly two weeks after the third betas, signaling steady progress toward the expected public releases this fall.
How to Download
Registered developers can obtain the updates directly on their devices:
• iOS 27 / iPadOS 27: Go to Settings > General > Software Update.
• macOS Golden Gate: Go to System Settings > General > Software Update (with Beta Updates enabled and a developer account linked).
Major Features in This Cycle
Both platforms continue to emphasize Apple Intelligence and a refined user interface centered around the new Liquid Glass design language.
Siri AI takes center stage as a more capable, chatbot-style assistant. It combines general world knowledge, personal context from apps like Messages and Mail, and on-screen awareness to deliver smarter responses. A dedicated Siri app now stores conversation history, and system-wide Write with Siri helps generate or refine text. On the Mac, users can also create custom voices with personalized pace and expressivity. Visual Intelligence has been enhanced and relocated (to the Camera app on iOS and integrated into the desktop on macOS) for better contextual understanding of what’s on screen.
Design and Performance Improvements include:
• Enhanced Liquid Glass with better opacity, readability, and a new transparency slider.
• Refined window shadows, uniform toolbars, edge-to-edge sidebars, and subtler rounded corners on macOS.
• Faster app launching, quicker keyboard appearance, improved AirDrop speeds, and smoother Wi-Fi-to-cellular handoffs across iOS devices.
• Overall performance optimizations that make the system feel snappier, even on older hardware.
Apple Intelligence Expansions add new capabilities in Photos, Safari (AI tab organization), Wallet, Passwords (automatic weak password updates), Shortcuts, and the revamped Image Playground app, which now supports photorealistic image generation.
MacDailyNews Take: With beta 4 now available, Apple is expected to continue refining stability, battery life, and features in the coming weeks. A public beta is likely to follow soon, ahead of the official launch of iOS 27, iPadOS 27, and macOS Golden Gate in September.

UPDATED: 06/22/26
Apple has released the second developer beta of macOS Golden Gate with more refinements to the new interface and AI features.
Beta 2 further improves the Liquid Glass design with better readability, updated window styling, and a new transparency slider that lets you control the amount of the glass effect.
Apple is also expanding Siri AI on the Mac. It now lives in Spotlight, has its own app for conversations, can answer questions about your files and what’s on your screen, and can help with writing.
This beta also includes additional AI features across apps like Photos, Safari, Passwords, and Image Playground as Apple continues preparing macOS Golden Gate for its public beta next month.

1. OCLP Users Warning
OpenCore Legacy Patcher is not compatible with macOS Golden Gate or macOS Tahoe. Make sure you go into System Settings > Software Update and turn off Download Updates and Install macOS Updates.
If you use OCLP on an unsupported Mac, wait for official OpenCore Legacy Patcher 3.0.0 testing and compatibility information before attempting to install.
2. Should You Install macOS Golden Gate Beta?
Most users should not install macOS Golden Gate Beta 1 on their main Mac. This is early beta software, which means apps may crash, battery life may be reduced, accessories may not work correctly, and some features may be unfinished.
Install it only if you have a test Mac, a full backup, and a reason to test the new release early. I recommend two types of backups: Time Machine & A direct copy of your important files and apps
This might seem like a lot, but TRUST ME, it will be worth it if something goes wrong!
MacAdmins, developers, and advanced users can begin testing app compatibility, MDM enrollment, security tools, VPN clients, printers, FileVault workflows, software update behavior, and deployment processes.

4. What’s New in macOS Golden Gate Beta 2?
Apple has released the 2nd developer beta of macOS Golden Gate 27.
New Features & Changes
Liquid Glass Design Updates
macOS Golden Gate brings a more polished Liquid Glass design with better readability, improved contrast, more consistent toolbars, edge-to-edge sidebars, updated window shapes, and refreshed menu bar icons. Apple has also added a new slider that lets you adjust the Liquid Glass look from very clear to fully tinted.
Performance Improvements
Apple says the system should feel faster overall, with quicker AirDrop transfers, faster network file browsing, faster Safari start page loading, improved Mail search ranking, and better Spotlight search suggestions.
Siri AI on Mac
The biggest new feature is Siri AI on Mac. Siri can now answer more natural questions, understand personal context, take actions inside apps, work from Spotlight, and live inside a new dedicated Siri app for longer conversations.
Visual Intelligence
Visual Intelligence is also coming to the Mac, letting you ask questions about what’s on your screen and get help based on the content you’re looking at.
Writing Tools & Apple Intelligence
Golden Gate expands Writing Tools with Siri, adds better AI photo editing, improves Image Playground, and lets you create Shortcuts from plain-language descriptions.
Safari & Passwords
Safari gets smarter tab grouping, page-change alerts, and faster start page loading. Apple is also adding one-click password fixes to help update weak or reused passwords more easily.
Family, Safety & Accessibility
Golden Gate includes stronger child safety controls, improved Screen Time features, and new accessibility improvements across the system.
Other Notable Changes
Other smaller changes include ultrawide display upgrades, better iCloud Shared Albums, Call Context, enhanced Flyover in Maps, swipe-to-refresh in more apps, and a refreshed video podcasts experience.

Apple has released the first developer beta of macOS Golden Gate Beta 27. This is the first major beta release of Apple’s next version of macOS.
Sadly, this will be the first macOS release in almost 20 years, and 17 macOS releases, that does not support Intel devices. We all knew this was coming, but it is still a bummer for sure.
Golden Gate is looking like a Snow Leopard-type release that focuses on performance across the system, including a rebuilt search index that should make Spotlight, Mail, Photos, and other search-heavy areas feel faster and more reliable. Apple also reworked a lot of the Liquid Glass interface, which was needed for sure. We now have a slider like iOS has, so we can use more or less of the glass effect.
The main story, though, is Siri AI finally becoming more useful on the Mac. It’s built into Spotlight, available as its own app for longer conversations, and can help with writing, file questions, Visual Intelligence shortcuts, and more contextual actions. Golden Gate also brings stronger Screen Time and parental controls, but there’s a major compatibility note: this looks like the end of Intel Mac support, and the newest

This database will contain download links for macOS full Installer pkg files (InstallAssistant.pkg). This file is the same full installer that you would download directly from the App Store for Intel and Apple Silicon M1/M2/M3/M4 Mac Computers. The InstallAssistant.pkg is stored on Apple’s servers and contains the full “Install macOS.app”. Once downloaded, all you need to do is install the pkg and the full installer of macOS will be in your applications folder. This change was made when Apple revised the full installer for Big Sur. The InstallAssistant.pkg is not available for Catalina or Mojave.
