Overview
- Apple pushed iOS 27, iPadOS 27, macOS 27 Golden Gate, watchOS 27, visionOS 27, and tvOS 27 to users on Sept. 14, 2026 as a coordinated major OS rollout.
- Siri AI, billed as a ground‑up rebuild of Siri offering conversational queries, on‑screen awareness, and app actions, launched as an English public beta that users must join via an in‑settings waitlist.
- Apple runs Apple Intelligence on a mix of on‑device AFM models (AFM 3 Core and AFM 3 Core Advanced) for privacy and smaller tasks, and larger AFM cloud variants for heavier inference; Siri conversation histories sync across devices using end‑to‑end encrypted iCloud.
- Two cross‑platform features previewed in betas—Suggestions in Messages and Automatically Fix Password—were pulled from the initial release and will arrive in a future software update, and several Apple Intelligence features require recent hardware such as iPhone 15 Pro or newer or Apple Watch Series 9+.
- Beyond Siri, iOS 27 delivers Apple Intelligence photo tools, Liquid Glass opacity controls, new parental controls, and performance gains (apps launch faster, Photos and AirDrop load quicker), while Apple says language expansion for Siri AI will roll out in October and some capabilities remain unavailable or limited in the EU and China.
