Beta 4 of iOS 10.2.1 and MacOS Sierra 10.12.3 Released for Testing
Apple has released the fourth beta versions of iOS 10.2.1 and macOS Sierra 10.12.3 to users participating in the beta testing programs.
The updated beta builds can be downloaded now from the software update mechanism of iOS or Mac OS for any device or hardware enrolled in the developer beta or public beta testing programs.
No new features are known or expected in either iOS 10.2.1 or macOS Sierra 10.12.3, suggesting the small point releases will focus primarily on bug fixes.
Considering that beta 3 of the same system software versions was released just a few short days before beta 4, it’s possible that the final version of each release will be unveiled to the general public soon as final builds.
