macOS 27 Golden Gate: the headline features
Siri rebuilt on Gemini
This is the biggest change. Siri now runs on Apple Foundation Models trained with Google’s Gemini, accessed via Private Cloud Compute. The pitch: Gemini’s intelligence with Apple’s privacy. Siri can finally hold context across turns, act across apps, see what’s on your screen, and use personal context. We covered the deal in Apple Google Gemini Siri $1 billion deal.
Liquid Glass refined
The translucent material system from iOS 26+ comes to the Mac. Apple specifically addressed accessibility feedback from iOS 26:
- Reduce Transparency is now the recommended setting for accessibility users
- Brighter menu bar contrast options
- Stage Manager gets clearer focus indicators
- Snap-to-edge tinting that adapts to wallpaper
Apple Intelligence expanded
- Image Playground 2 — better photorealism, on-device generation
- Genmoji animation — emoji that animate based on context
- Writing Tools v2 — adaptive tone matching, multilingual rewrite
- Photos cleanup — better object removal (still on-device)
- Live Translation — 18 languages on FaceTime and Messages
- Smart Replies — proactive on-device suggestions in Mail, Messages
Parental controls overhaul
Apple announced expanded parental control hooks: app limits per category, communication safety in third-party apps via an API, location and screen-time inheritance from family accounts, and AI-assisted Screen Time recommendations. This is a direct response to U.S./EU regulatory pressure on kid safety.
Drops Intel Mac support
This was inevitable. The 2019 Mac Pro was the last x86 Mac to ship. Apple silicon-only is now reality for new macOS releases.
