Apple has released macOS 27 Golden Gate beta 6 to developers after a brief three‑week pause between betas 4 and 5. The update introduces a dedicated Siri app, standardizes window corner radii, and adds AI‑powered features to Shortcuts and Safari. Users can now create extensions and automations with simple prompts, and Safari gains a pull‑to‑refresh gesture that hints at a more touch‑friendly macOS ahead of rumored touchscreen MacBook Pros.

The build, 26A5416b, also revamps the iPhone Mirroring app, enabling window resizing to various aspect ratios—a preview of the anticipated foldable iPhone Ultra. While beta 5 mainly refreshed app icons for Siri, Chess, and Safari, beta 6 adds tangible functionality and bug fixes, positioning macOS closer to its final release.

Developers can install the new beta by backing up their Mac, opening System Settings → General → Software Update, tapping the “i” next to Beta Updates, and selecting the macOS Developer Golden Gate Beta from the dropdown. This workflow ensures developers stay current with the latest changes.
