Run macOS 27 Golden Gate: How to Install the Public Beta and Test Siri AI

The macOS 27 Golden Gate public beta is officially live, giving Mac users their first hands-on experience with the highly anticipated Siri AI overhaul and the new Liquid Glass interface. If you are tired of a cluttered desktop or want to test Apple's next-generation AI tools before the fall release, this beta delivers significant workflow upgrades.

• Verify your hardware compatibility. This ensures your Mac can run the update, as it requires an M1 chip or later, or the A18 Pro MacBook Neo. Intel Macs are no longer supported.
• Check for the M3 chip if you want advanced features. This enables on-device Siri processing for natural voice selection and upgraded dictation.
• Note the regional restrictions. This means Siri AI is currently unavailable in the European Union and China, and will remain blocked at launch.
• Create a Time Machine backup. This provides a safe rollback path to macOS Tahoe if you encounter critical beta bugs.

1. Sign up at Apple's beta testing website. This registers your Apple ID for the public beta program.
2. Navigate to System Settings, then click General, followed by Software Update. This accesses the system's update portal.
3. Click the "i" icon under the Beta Updates section and select macOS 27 Golden Gate Public Beta. This prompts your Mac to fetch and install the beta like a standard software update.

• Adjust the new Liquid Glass slider. This enables you to customize UI transparency, choosing between a clearer background view or a more opaque look for better legibility, complete with refined window shadows and uniform toolbars.
• Trigger Siri AI using the unified Spotlight bar via the Command + Space shortcut. This allows you to interact with a smarter, chatbot-like Siri that can search files, access personal data across devices, and complete in-app tasks.
• Activate Visual Intelligence using Command + Shift + Space or Command + Shift + 6. This lets Siri analyze your screen to translate text, identify objects, or extract nutritional information, mirroring the iPhone experience.
• Select a custom screen area for Visual Intelligence by pressing Command + Shift + 5. This opens an adjustable selection square to target specific on-screen elements for Siri to analyze.
• Right-click in any app to use the Write with Siri feature. This goes beyond standard Apple Intelligence Writing Tools, allowing Siri to compose full emails in your personal style, fix grammar, or generate text from scratch.
• Resize the iPhone Mirroring window by dragging its corners. This gives you flexibility to view apps in larger formats, supporting landscape or iPad layouts where applicable.
• Create automations in the Shortcuts app using natural language. This leverages AI to build and refine custom shortcuts simply by typing what you want them to do.

Safari introduces a Describe Extension feature, allowing you to generate custom browser extensions instantly using AI. By clicking the settings icon in the URL bar, you can type natural language prompts to create tools on the fly. Apple provided the following exact examples of what you can generate:

• Display a reading time estimate as a badge on the extension
• Close duplicate tabs pointing to the same URL when I click the extension
• Highlight this word
• Create a 3-minute focus timer for the page
• Set the minimum font size to 14pt
• Every time I open a new tab, draw me a flower
• Highlight and show the dimensions of webpage elements when I click them
• Enter design mode for a website so that I can edit the contents
• Save this recipe

• Monitor webpages in Safari with automated tab grouping. This organizes related tabs automatically and sends notifications for Hourly, Daily, Weekly, or Monthly webpage updates.
• Experience faster system animations and AirDrop transfers. This results from underlying code cleanups that smooth out scrolling, Mission Control, Spaces, and network file browsing.
• Search faster in Mail, Photos, and Messages. This is driven by a rebuilt search foundation that improves indexing reliability and surfaces recent items and relevant emails instantly.

The release of the macOS 27 Golden Gate beta marks a definitive turning point for Apple's hardware ecosystem. By completely dropping support for Intel Macs, Apple is drawing a hard line in the sand: the future of macOS is inextricably linked to Apple Silicon and on-device AI processing. The requirement of an M3 chip just to access upgraded dictation and natural voice features highlights how rapidly the hardware demands for AI are scaling, even within Apple's own custom silicon lineup.

Furthermore, the geographic restrictions blocking Siri AI in the European Union and China underscore the growing regulatory fragmentation of global tech. While users in supported regions get a transformative, system-wide AI assistant that can read their screens and draft emails, a massive portion of the global market is receiving a fundamentally different, less capable operating system. This regional disparity could complicate developer adoption of the new AI APIs if a significant chunk of their user base cannot access them.
