macOS Golden Gate 27 Announced
Much like Mac OS X Snow Leopard in 2009, Apple said it focused on improving macOS’s performance and dozens of underlying technologies this year.
Apple says macOS Golden Gate offers quicker AirDrop transfers, faster network file browsing, improved syncing in the Messages app, better Spotlight search suggestions, and other changes that make your Mac feel “more responsive than ever.”
I had lots of problems installing beta 1 via Software Update, so I recommend downloading the full installer or IPSW. I eventually got it to work by updating to macOS 26.5.1 first (instead of installing on top of 26.4) and by booting into recovery multiple times to use Startup Security Utility to toggle the LocalPolicy from Full Security to Reduced Security and back.
macOS Golden Gate 27 Beta Release Notes:
The Recents list in the open and save panels can be accessed with the keyboard shortcut cmd-shift-f.
[…]
Unified Logging System archives generated on 27.0 releases cannot be read on macOS 26.1 or earlier due to an updated archive format.
[…]
Encrypted HFS+ (CoreStorage) is deprecated and will not be supported in a future version of macOS.
[…]
Starting in 27.0 operating systems, select system processes now enforce stricter network security (TLS) requirements. These new requirements might cause connections to fail if the server does not meet them.
[…]
Devices configured with Reduced Security mode might fail to install macOS 27 beta 1.
[…]
Accessing files in other developer teams’ app data containers and app group containers no longer prompts the user for authorization; such accesses are denied by default and can be managed by the user in Privacy & Security settings.
[…]
Apps can no longer access the local TCC database directly.
Visual Intelligence on macOS Golden Gate 27 is getting a dedicated keyboard shortcut. Similar to the screen capture shortcut, it lets users select portions of the screen and get contextual answers around that. From there, users can also continue the interaction from the Siri app.
When using a wired network adapter with a live connection, macOS now displays a network menu bar item!
I love this “More in Accessibility Settings…”
Apple adds native ultrawide display support in macOS 27 Golden Gate, bringing higher resolutions and persistent display arrangements to users of widescreen monitors.
macOS 27 Golden Gate brings a major improvement to iPhone Mirroring, allowing users to resize the window beyond the iPhone’s fixed aspect ratio for the first time.
Currently, there seem to be several fixed aspect ratios available for resizing the iPhone Mirroring window, meaning the system adjusts the window to the nearest supported shape rather than allowing users to choose any arbitrary aspect ratio.
iPhone Mirroring app has many, many more zoom level options now, which I very much appreciate. Thank you, whoever did that.

They removed menubar icons, mostly, but mostly doesn't get full credit not even close, there are still a few remaining ones and they suck. They de-rounded the window corners a bit, because they can't admit they fd up and make them the same as Sequoia. The handle for slider controls still turns into an ugly glass blob when you move it and it stretches in an ugly way when in motion. Toolbars are still hideous with the hideous popout buttons for the touchscreen Macs coming soon that almost no one asked for. Safari tabs are really really bad still and the Safari titlebar and tab area is still translucent which makes the content of certain tabs bleed through in a horrible ugly way. On the positive they added a transparency slider that does almost nothing as a primary fu to us haters. Overall: barely anything changes, 27 is almost as horrible and hideous as 26. If you hated 26, you're definitely going to hate 27. Staying on Sequoia indefinitely, Apple has communicated clearly for 2 years now that they will keep going on this stupid path.
