Apple on Monday released second betas of what would become the macOS Sierra 10.12.5, watchOS 3.2.2 and tvOS 10.2.1 software updates. macOS Sierra 10.12.5 beta 2 (build 16F54b), watchOS 3.2.2 beta 2 (build 14V5475a) and tvOS 10.2.1 beta 2 (build 14W5573a) are now available to Apple’s registered developers over the air or as standalone downloads via the Apple Developer Center.
The release note for the latest beta releases from Apple does not provide much insight into what’s new in them, but looking at how quickly Apple has released them, it is likely that we are looking at behind-the-scenes tweaks, and other improvements, without adding any major new forward-facing features for users.
To update to the latest beta, developers can grab the file from Apple’s Developer Center or via an OTA update with the proper configuration file installed.
to update the watchOS software, owners must download the new software through the dedicated Apple Watch app on the iPhone, then going to General –> Software Update. From there, owners must install the software, and the Apple Watch must have 50 percent battery life. The Apple Watch must also be placed on its charger, and it has to be within range of the iPhone.
To update the latest generation of tvOS, the Apple TV 4 must be connected to a computer via the USB-C cable, and installing the latest software by that means. The software can be downloaded from the dedicated developers website.
As mentioned above, this new software is a minor upgrade, so there likely won’t be any major new revelations discovered. If anything new is found, though, we’ll update accordingly.
