Overview
- Apple made macOS Golden Gate publicly available on Tuesday, September 15, 2026, as a free upgrade that installs from System Settings on Macs with an M1 chip or later and the A18 Pro MacBook Neo.
- The marquee change is a chat-style Siri AI that runs across the system, offering a dedicated Siri app, conversational Spotlight queries, Visual Intelligence to analyze screen content, and a Write with Siri tool for composing and editing text.
- Golden Gate ends official support for Intel Macs and fragments feature levels by hardware because some Siri processing and upgraded dictation require newer chips such as M3 or later.
- Apple uses a hybrid architecture that combines on-device models with private cloud compute for heavier inference, and reporting says parts of the cloud workload are handled by Google Gemini with region- and device-based limits for features like Siri AI in the EU.
- Beyond AI, the update adds a Liquid Glass opacity slider, faster animations, rebuilt search and indexing for Spotlight, Mail and Photos, quicker AirDrop transfers, and steadier external-display window behavior, which should make everyday use feel snappier for supported Macs.
