Here’s what to expect.\n\n## Apple rolls out macOS 27 developer beta 6\n\nWith the final stretch before its official release fast approaching, Apple is now rolling out macOS 27 Golden Gate beta 6 to all developers.\n\nLast week, [beta 5](https://9to5mac.com/2026/08/10/macos-27-golden-gate-beta-5-now-available-to-developers/) introduced new app icons for several apps, including Siri, Chess, and Safari, but didn’t introduce any other relevant features (or bugs, for that matter).\n\nmacOS 27 Golden Gate introduces a dedicated Siri app, unifies corner radii across windows and apps, and adds AI-powered features to Shortcuts and Safari, allowing users to create extensions and automations with simple prompts.\n\nThe system also introduces a new pull-to-refresh gesture in Safari, which many see as an early sign that Apple is making macOS more touch-friendly ahead of the rumored touchscreen MacBook Pros.\n\nmacOS 27 Golden Gate also revamps the iPhone Mirroring app, allowing users to resize its window to different aspect ratios, a change similarly seen as foreshadowing the rumored foldable iPhone Ultra, which is expected to be announced next month.\n\nThe release build for macOS 27 Golden Gate is 26A5416b.\n\n## Installing the macOS 27 Golden Gate beta\n\nHere’s [how to install](https://developer.apple.com/support/install-beta/#macos-beta) the macOS 27 Golden Gate developer beta 5:\n\n[Back up](https://support.apple.com/en-gb/102307)your Mac- Open System Settings\n- Go to General ⇾ Software Update\n- Click the ‘i’ icon next to Beta Updates\n- From the dropdown menu in the top-right, select the macOS Developer Golden Gate Beta\n- Hit ‘Done’\n\nDid you spot anything new in today’s macOS 27 Golden Gate beta?
