Apple on Tuesday seeded the fourth beta of macOS Sierra 10.12.1 to developers and public beta testers for testing. The new seed comes one week after the release of the third beta seed.
The new beta – build 16B2548a – can be downloaded by developers via the Apple Developer Center, or via the “Update” tab in the Mac App Store. All beta testers who are a part of the Apple Public Beta Tester program will be able to download and install the new beta via the “Update” tab in the Mac App Store.
So far, it looks as if the beta of macOS Sierra 10.12.1 is focused on under the hood stuff, such as bug fixes and performance enhancements. Although the original beta did add album support to Photos for the new Portrait feature in iOS 10 for iPhone 7 plus owners.
In related news, Apple on Monday seeded the third betas of iOS 10.1, and tvOS 10.0.1 to developers for testing.
