macOS 27 is the upcoming twenty-third release of macOS, announced at WWDC26 on June 8, 2026, and currently in beta ahead of an expected fall 2026 release. As a pre-release version, details reflect the beta and may change. It is the first macOS that requires Apple silicon, macOS Tahoe having played Intel's farewell — ending the twenty-year x86 era and simplifying the platform to a single architecture for the first time since the PowerPC sunset.

The release carries the generation's Siri AI centerpiece to the desktop — the rebuilt assistant with its dedicated app, on-screen awareness, and in-app actions, folded into Spotlight's action system — alongside Liquid Glass refinements, the shared Photos and Shortcuts intelligence features, and the parental-controls suite arriving family-wide.

Siri AI and the Siri app integrated with Spotlight actions; Liquid Glass tuning; Photos Spatial Reframing and Extend; Describe a Shortcut; parental controls (Ask to Browse, Time Allowances, Schedules); and continued performance work on Apple silicon.

Beta coverage weighs Siri AI's desktop utility — assistant-driven file and app actions against Spotlight's existing muscle — and notes the quiet historical marker: the first Mac release with no Intel build. This page will need updating at release.
