Overview
- Apple released macOS 27 Golden Gate beta 6 on Monday, making the build available to developers and reported public beta testers for download.
- The most visible change is a Liquid Glass redesign of the three circular traffic‑light window controls, which adds subtle shadows and a more three‑dimensional, glass‑like look that appears across every app window.
- Beta 6 adds two dynamic Golden Gate wallpapers (day and evening) that animate when you unlock your Mac and can run as screensavers showing cars crossing the bridge.
- The update also refreshes the Preview app icon to match the iOS 27 redesign and includes fixes for window shape consistency that varied under macOS 26 Tahoe, with no major new developer APIs in this build.
- Apple’s recent beta cadence and the focus on polish indicate the company is finalizing visuals and stability ahead of an expected public release in September 2026.
