Just a day after releasing the new macOS Sierra 10.12.1 beta to developers, Apple is now pleased to roll out the third beta build for the upcoming update to public beta testers.

AppleInsider reports the third macOS Sierra 10.12.1 beta version was made available to public beta testers early Tuesday, which is almost a week since the second beta build was released for both developers and public beta testers to try out.

Beta testers who are enrolled in Apple’s beta testing program can now download the third beta via the Software Update menu option in the Mac App Store. For Mac owners who have yet to be part of Apple’s beta testing program, they can still sign up to participate in the testing that will conclude with the official release of the 10.12.1 update later this month.

The third macOS Sierra 10.12.1 beta could be the last beta version before the official update is released, so it pretty much contains all of the bug fixes and performance improvements the official release comes with. It even has album support for the new Portrait feature the iOS 10 is bringing to the iPhone 7 Plus, according to MacRumors. What this album does is organize the images captured using the Portrait mode in the Photos app.

Apple’s macOS Sierra was released on Sept. 20 to public users. It came with Apple Pay support for Safari, deeper iCloud integration, support for a remote unlocking mechanism via the Apple Watch and Mac support for Siri. Beta testing commenced after the new Mac OS’s release, however, to address certain issues found in the new operating system.

Aside from the third macOS Sierra 10.12.1 beta version, Apple also started rolling out watchOS 3.1, tvOS 10.0.1 and iOS 10.1 beta this Tuesday. Meanwhile, the Cupertino giant is rumored to be launching its new MacBook Pro and possibly a new iMac alongside the release of the official macOS Sierra 10.12.1 update.
