Just a day after releasing macOS Sierra to the public, Apple launched macOS Sierra 10.12.1 as a point-one update to developers. The first beta is now available for download to developers who are part of Apple’s beta testing program.

According to MacRumors, Apple seeded macOS Sierra 10.12.1 for developers to try out before the official update rolls out for the new operating system of Mac devices. The beta is downloadable through the Apple Developer Center and the Mac App Store.

Apple did not state what this point-one update contains, but it is expected to improve some implementations and fix bugs and issues found between the beta testing period and the official release of macOS Sierra on Tuesday.

The macOS Sierra 10.12.1 beta with build code 16B2327e may be available to developers for now, but it is expected to be seeded to Apple’s public beta testing program members in the coming days, as per Apple Insider.

As previously reported, macOS Sierra comes with new features, such as support for Safari browser-based Apple Pay, remote unlocking capability via an Apple Watch called Auto Unlock, deeper iCloud integration, Picture in Picture multitasking and many more. It was publicly released just less than a week since the second Gold Master version was rolled out to developers.

The new macOS Sierra 10.12.1 beta isn’t the only point-one update Apple rolled out to developers this Wednesday. The Cupertino giant also launched point-one updates for iOS 10 and watchOS 3 — iOS 10.1 and watchOS 3.1, respectively. Even tvOS 10 that was released last week also got a point-one update that reportedly squashes bugs identified recently.
