Apple has released macOS 27 Golden Gate public beta 3 (build 26A5406e) to public beta users, following the developer beta 5 released on August 10, 2026. The update revamps icons for Siri, Activity Monitor, Safari, the App Store, and Chess, and introduces the new Siri app, prompt-based Shortcuts and Safari extensions creation, and a Liquid Glass intensity slider. It also standardizes corner radii across windows and apps, addressing a complaint about macOS Tahoe 26.

Users enrolled in Apple’s public beta program can now install macOS 27 Golden Gate public beta 3. Here’s what’s new in the system. macOS 27 Golden Gate public beta 3 now available After yesterday’s release https://9to5mac.com/2026/08/10/macos-27-golden-gate-beta-5-now-available-to-developers/ of macOS 27 Golden Gate beta 5 for developers, Apple is now rolling out that same version as the system’s third public beta. Yesterday’s beta didn’t include any major new features, but it did revamp several icons, including Siri, Activity Monitor, Safari, the App Store, and Chess. macOS 27 Golden Gate https://9to5mac.com/2026/06/08/apple-announces-macos-golden-gate-27/ introduces the new Siri app, alongside the revamped Siri AI assistant. It also features prompt-based Shortcuts and Safari extensions creation, and allows users to control the Liquid Glass intensity with a slider during setup, or in System Settings. The update also standardizes corner radii across windows and apps, addressing a common complaint about macOS Tahoe 26.
