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.

Final Notes
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.

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.
8. Apple Silicon macOS Golden Gate IPSW Restore File
An IPSW restore file is mainly used to restore or revive Apple Silicon Macs with Apple Configurator, Finder, or another Mac.
Most users do not need the IPSW file for normal macOS updates. IPSW files are intended for restores, revives, troubleshooting, clean installs, and testing workflows.
Use this link to download the full Mac IPSW restore file directly from Apple:
The delta update & upgrade size will automatically change in size for exactly what your macOS version needs. For example the smallest update size will be from Beta 3 to Beta 4. But if you are upgrading from Beta 1 to Beta 4, the upgrade size will need to include all the fixes in Beta 2 and 3.
Apple Silicon Updates
Delta from macOS Golden Gate Beta 3 with size = 6.93GB
Upgrade from macOS Tahoe 26.5.2 with size = 20.24GB
10. Apple Silicon Firmware & iBoot Versions
The Apple Silicon firmware and iBoot versions included with macOS Golden Gate Beta are listed below.
