TL; DR (tap to expand)
- macOS 27 Golden Gate drops Intel support entirely, runs on all Apple Silicon Macs, and brings up to 30% faster app launches, 70% faster photo operations, and 80% faster AirDrop transfers.
- Siri AI becomes a dedicated app with memory, on-screen awareness, multi-step actions, and a hybrid Apple Foundation Models + Google Gemini architecture through Private Cloud Compute.
- Apple has refined Liquid Glass, rebuilt Spotlight, expanded Apple Intelligence across nearly every core app, and introduced new AI frameworks for developers.
Apple unveiled macOS 27 Golden Gate during WWDC 2026 as the next major version of macOS. Rather than introducing a dramatic redesign, Golden Gate focuses on improving speed, refining the interface, and expanding Apple Intelligence across the operating system.
Developer beta 1 is available immediately, a public beta will arrive in July, and the final release is scheduled for September/ October alongside Apple’s next wave of Mac hardware.
macOS 27 Ends Intel Mac Support
Golden Gate is the first macOS release to support only Apple Silicon Macs. Supported devices include:
- MacBook Air (M1 and newer)
- MacBook Pro (M1 and newer)
- iMac (M1 and newer)
- Mac mini (M1 and newer)
- Mac Studio (M1 Max and newer)
- Mac Pro (M2 Ultra and newer)
All core Apple Intelligence features, Siri AI capabilities, and performance improvements work on M1 Macs and newer devices. However, Apple’s most advanced on-device AI model requires an M3 chip or newer with at least 12GB of unified memory. These models power advanced Siri voices, improved dictation, and certain generative AI tasks.
Siri AI Becomes a Full Assistant
The headline feature of macOS 27 is the arrival of Siri AI. Apple has rebuilt Siri as a standalone application with persistent conversation history and contextual memory. Siri can now understand information across apps and maintain context between requests instead of treating each command independently.
Users can grant Siri access to photos, messages, files, calendar events, reminders, and other personal data. Siri can summarize selected Finder files, generate workflows, create automations, and execute multi-step actions without requiring additional instructions.
The assistant also understands what is visible on-screen and can respond based on currently open content.
For example, users can select several documents in Finder and ask Siri to summarize them, or describe a workflow and have Siri generate the required Shortcuts automation. Siri can also be launched directly from Spotlight.
Apple has redesigned Siri’s voice engine with more natural speech patterns, adjustable pace controls, and customizable tone settings.
Under the hood, Siri uses Apple’s Foundation Models for privacy-sensitive local processing. More demanding requests can be routed through Google Gemini using Private Cloud Compute. Apple says neither Apple nor Google can access personal user data during processing.
The entire Siri experience syncs across macOS 27, iOS 27, and iPadOS 27.
Liquid Glass Gets a Major Refinement
Following criticism of readability and transparency effects in macOS 26 Tahoe, Apple has made substantial adjustments to Liquid Glass. Users now get a system-wide control for the intensity of Liquid Glass, with Clear and Tinted on each end of the slider.
Apple has standardized window corner radii across the entire operating system, including third-party applications. Sidebars now stretch edge-to-edge, toolbar layouts are more consistent, and app icons have received layer-by-layer updates for improved detail and contrast.
The company has also refined refraction effects to improve text legibility while maintaining the glass-inspired visual style.
Significant Performance Improvements Across Apple Silicon Macs
Apple claims Golden Gate delivers some of the largest responsiveness gains in recent macOS history.
Key improvements include:
- Up to 30% faster cold app launches
- Up to 70% faster photo library imports, searches, and scrolling
- Up to 80% faster AirDrop transfers
- Faster Safari start page loading
- Faster network file browsing
Apple says new CPU scheduling and memory management systems reduce thermal throttling and improve multitasking performance, including on first-generation M1 Macs.
Golden Gate also adds improved ultrawide display support with proper high-resolution scaling options. The built-in video podcast player has also been completely redesigned.
Apple Intelligence Expands Across Core Apps
Photos
Photos receives one of the largest upgrades through a new Spatial Reframe feature. The tool can convert standard 2D images into editable 3D scenes. Users can reposition subjects, alter viewing angles, and expand backgrounds while preserving image quality.
Clean Up has been improved and a new Extend tool joins the editing suite.
Safari
Safari gains automatic tab organization that groups tabs by topic. A new Notify Me feature can monitor webpages and notify users when specific changes occur, such as event registrations opening, products returning to stock, or information being updated.
Messages and Calendar
Apple Intelligence can automatically suggest relevant photos when users request them inside conversations.
Calendar can generate complete events from natural-language descriptions, automatically identifying locations, dates, and contacts.
Passwords
The Passwords app can detect compromised credentials and automate much of the recovery process.
With a single action, macOS can visit the affected website, generate a stronger password, fill required forms, and update stored credentials.
Home
The Home app can combine recordings from multiple cameras into a single continuous event timeline. Apple demonstrated examples such as package deliveries captured across several cameras around a property.
Shortcuts
Shortcuts can now generate complete workflows entirely from natural-language instructions with the help of Siri.
Spotlight
Spotlight receives a complete infrastructure overhaul. Apple says indexing is now significantly faster and more accurate across Mail, Photos, files, applications, and system content. Users can also ask Siri AI questions about selected files directly from Finder context menus.
Availability
Developer Beta 1 is available now through the Apple Developer Program. Public beta testing begins in July 2026. The final version of macOS 27 Golden Gate will be released in September/ October 2026.
Apple says Siri AI and Apple Intelligence will launch in English (US) first, with additional languages arriving later.
