The End of Intel on Your Mac: macOS 27 Golden Gate, Apple Silicon, and What Changes Now
At WWDC 2026 on June 8, Apple’s Craig Federighi, Senior Vice President of Software Engineering, introduced macOS 27 Golden Gate — the twenty-third major release of macOS and the first to run exclusively on Apple Silicon. Named after the strait connecting the San Francisco Bay to the Pacific Ocean, Golden Gate builds on three priorities announced during the keynote: platform improvements and performance, trust and safety including new child protection tools, and a substantial forward step for Apple Intelligence.
The most immediate shift is hardware. Any Mac with an Intel processor will not run macOS 27. The last Intel models were dropped alongside macOS 26 Tahoe, and Golden Gate makes that cut permanent. For owners of the remaining Intel Macs — the MacBook Pro (16-inch, 2019), MacBook Pro (13-inch, 2020, Four Thunderbolt 3 ports), iMac (2020), and Mac Pro (2019) — macOS Tahoe is the end of the line for major updates. Those machines will continue to receive security patches for approximately three years after Tahoe’s release. Beyond that, macOS 27 ushers in an AI-first era built entirely for Apple’s own chips. For context on the broader platform trajectory, see iOS 26.5’s RCS end-to-end encryption update and the parallel changes across Apple’s 2026 operating system family.
Siri AI — a fully rebuilt assistant
macOS 27 introduces Siri AI, a rebuilt version of Siri with a dedicated standalone app and deep integration into the macOS 27 interface. It appears as a compact chat window on screen. Users can type questions directly into Spotlight and the system hands the prompt to Siri AI automatically.
Right-clicking a file — or multiple files — brings up a context menu with a prompt box that lets users ask Siri questions based on the content of those files. Siri AI can also assist with writing and proofreading across Mail, Messages, and other apps. Advanced voice and dictation features require an M3 Mac or newer with at least 12 GB of unified memory. For the broader Apple Intelligence picture, see recent iOS testing leading into WWDC 2026.

Safari — AI extensions, custom shortcuts, and Notify Me
macOS 27 brings three notable Safari additions. Users can describe a custom Safari extension in plain language and have Siri AI build it — no coding required. The same natural language approach applies to creating new Shortcuts: a “Describe a Shortcut” prompt replaces manual workflow construction. Both features are aimed at making these tools accessible to users who have never configured them before.
Notify Me is a new passive web monitoring feature. Users can set a watch on any part of a web page — a product page, a pricing table, an event listing — and receive a notification when the content changes. One practical example given during the keynote: using Apple Intelligence to automatically purchase a product once it becomes available.
- Custom ExtensionsDescribe what you want an extension to do in plain text. Siri AI builds it.
- Describe a ShortcutNatural language Shortcuts creation — no workflow editor needed.
- Notify MeMonitor any webpage for changes. Receive a device notification when it updates.
Image Playground — photorealistic generation and photo tools
Image Playground receives an update in macOS 27 with a new photorealistic image model and the ability to transform photos into multiple styles. The Photos app gains built-in AI editing: cleaning up images, extending backgrounds, and reframing photos — all processed on-device.
These updates are not exclusive to macOS. Image Playground is available across Apple’s device ecosystem, and the push for cross-device feature parity was a recurring theme at WWDC 2026. All on-device processing means images are not uploaded or shared with any server.

- ⬛ Background extension and reframing

Contextual awareness — your Mac understands your schedule
Apple Intelligence in macOS 27 can respond to context across apps. For example, Apple Intelligence can create a Calendar event based on the content of a conversation in Messages, or set an alert in the Reminders app when a user visits a website about an upcoming event. These actions happen within the existing app ecosystem without requiring extra steps.
Siri AI is also integrated with Calendar management. Users can ask Siri to create events and, where availability information is present, Siri can check the user’s calendar before responding to meeting invites. The feature is available on all Apple Silicon Macs running macOS 27, with more capable on-device models reserved for M3 devices or newer with at least 12 GB of unified memory. For related context, see iOS 26.4.1’s iCloud and CloudKit sync improvements.
- Message mentions a meeting → Calendar event created automatically
- Visiting an event page → Reminders app alert offered before leaving the site
- Meeting invite received → Siri checks your availability and assists your reply
Liquid Glass refinements — a new slider for transparency
macOS 27 adds a more uniform toolbar across apps in response to user feedback about the Liquid Glass design introduced in macOS 26 Tahoe. A new slider lets users choose how much Liquid Glass appears in the interface. One end of the spectrum is Ultra Clear; the other is Tinted Glass. The setting is system-wide.
Apple described the additions as general improvements alongside the main AI-focused updates. The slider is available on all compatible Apple Silicon Macs.

Child and teen safety controls
macOS 27 adds new child and teen safety tools to all of Apple’s operating systems. Parents gain additional control over app access, online content, and in-app spending. Custom schedules can be set for school hours, study time, and weekends. Apple has a dedicated safety hub at apple.com/child-safety with full details on all parental controls and communication safety features across Apple’s platforms. For context on the concurrent iOS update path, see iOS 26.3.1’s Studio Display support and bug fixes.
Liquid Glass — the transparency slider
A new slider in system settings lets users adjust how much Liquid Glass effect appears across macOS. The control runs from Ultra Clear at one end to Tinted Glass at the other. Apple also updated the toolbar design to be more uniform across apps in response to user feedback from macOS 26 Tahoe. The interactive preview below shows how the setting changes the visual presentation.
macOS 27 Golden Gate was covered here across its hardware compatibility changes, the Intel Mac exit, the Rosetta 2 transition timeline, the rebuilt Siri AI and its chip-tier requirements, new Safari features including custom extension creation and Notify Me, updates to Image Playground, contextual Apple Intelligence tools, child and teen safety additions, and Liquid Glass refinements. The developer beta is available now for those with an Apple Developer account. The first public beta is expected in July 2026. The macOS 27 release notes on Apple’s developer documentation site have additional technical detail for developers preparing their apps.
