14 DAY TRIAL // Today, January 9, 2017, Apple has refreshed its Beta releases with the third installation in the upcoming series of the iOS 10.2, macOS 10.12 Sierra, watchOS 3.1, and tvOS 10.1 operating systems.
Beta 3 and Beta 2 builds have been seeded for iOS 10.2.1, macOS 10.12.3 Sierra, watchOS 3.1.1, and tvOS 10.1.1, which are now available for developers and public testers alike, allowing anyone to test drive the upcoming maintenance releases of Apple's operating systems for mobile, desktop, Apple Watch, and Apple TV.
The new Beta versions are tagged as build 16D25a for macOS 10.12.3 Beta 3, build 14D23 for iOS 10.2.1 Beta 3, build 14S959 for watchOS 3.1.3 Beta 2, and build 14U711 for tvOS 10.1.1 Beta 2. As expected, the tvOS 10.1.1 Beta is only available for the 4th generation Apple TV as Apple is no longer supporting the 3rd generation model.
As for the changes brought by the new Betas, the release notes inform us that iOS 10.2.1 Beta 3 makes it possible for the new TV app to be restored after it is deleted. tvOS 10.1.1 Beta 2 includes general bug fixes and security improvements, and the macOS Sierra 10.12.3 Beta 3 update improves the stability, compatibility, and security of your Mac.
Here's how to install the new Beta builds Apple has seeded
If you're using a previous Beta release of the upcoming iOS 10.2.1, macOS Sierra 10.12.3, watchOS 3.1.1, and tvOS 10.1.1 operating systems, you should already know how to update your device to the newly announced builds. Please note that, in order to be able to install watchOS 3.1.1 Beta 2, you'll need to have the latest Beta of iOS 10.2.1 installed.
Run the Sierra Developer Beta Access Utility to download and install the latest macOS Sierra 10.12.3 Beta. We've also prepared two in-depth tutorials that'll teach you how to install the iOS 10 and macOS Sierra Betas so check them out here and here. However, we have to warn you that you shouldn't install these builds if you're looking for a stable experience.
