Just a few days after kicking off the public beta season and releasing a revised version of macOS 27 developer beta 3, Apple is now rolling out macOS 27 developer beta 4. Here are the details.
Last week, Apple released macOS 27 public beta 1, with the same build as a revised version it also rolled out for macOS 27 developer beta 3.
This means that, barring any show-stopping bugs, today’s developer release will also be rolled out as macOS 27 public beta 2 in the coming days.
macOS 27 developer beta 3 fixed some of the reliability issues introduced with macOS developer beta 2 and introduced new Golden Gate-themed wallpapers and screensavers, as Apple continues its work towards the official release later this year.
macOS 27 Golden Gate brings several improvements to Liquid Glass, including a slider that lets users precisely adjust how transparent or opaque UI elements appear. It also standardizes rounded corners across system windows, apps, and programs, addressing a frequent complaint in macOS 26.
Additionally, macOS 27 Golden Gate features the new Siri AI and its companion app, which leverages a new indexing system under the hood to more precisely include relevant information as the basis for Siri to generate answers. Siri AI and macOS 27 Golden Gate as a whole rely on the third-generation Apple Foundation Models, and you can read more about them here.
The build version for macOS 27 Golden Gate beta 4 is 26A5388g. We are digging through the new beta and will report back with what we find.
Here’s how to install the macOS 27 Golden Gate developer beta 4:
