Beta 4 of MacOS Sierra 10.12.2, iOS 10.2, WatchOS 3.1.1
Apple has released the fourth beta versions of their various system software releases, including macOS Sierra 10.12.2 beta 4, iOS 10.2 beta 4, and watchOS 3.1.1 beta 4.
The new beta updates continue to improve on prior beta releases, focusing on bug fixes and minor feature enhancements to the various Apple system software versions.
No major new features are expected in the iOS, MacOS, and WatchOS releases, though there will be new Emoji icons available across the board. iOS also will get some more obvious Shuffle and Repeat buttons in the continuously redesigning Music app.
Users who are enrolled in the eligible beta testing programs can find the latest versions of MacOS 10.12.2 beta 4 and iOS 10.2 beta 4 from the appropriate software update mechanisms through the App Store or Settings app, respectively.
Apple typically goes through multiple beta versions of system software before releasing a final version, perhaps suggesting that iOS 10.2 and MacOS 10.12.2 final versions could be made available by the end of the year.
