Apple posts first macOS Sierra 10.12.3, iOS 10.2.1, tvOS 10.1.1 betas for developer testing

Wasting no time, Apple has posted the first developer-only betas of macOS 10.12.3, iOS 10.2, and tvOS 10.1.1 just a day after releasing 10.12.2.




At this point, not much is known about the first macOS Sierra 10.12.3 beta, with no specific focus on areas listed to test. The beta is a 1.04 GB download, and is available through Developer's portal or through Software Update for registered devices.

The iOS 10.2.1 beta is a 1.82GB download, and similarly has no particular areas of focus, and given the number of the release is likely aimed at bug fixes, and not introduction of new features. The iOS 10.2.1 beta is only available as an over-the-air update, and not as a standalone download at this time.

Apple's tvOS 10.1.1 beta is also available, and can be installed for registered devices over-the-air, or through a computer running iTunes with a USB-A to USB-C cable. What is included in the new version is also unknown, but like the iOS beta, the update is probably aimed primarily at bug fixes.

Tuesday's mac OS 10.12.2 update brought new emoji, Apple Watch auto-unlock fixes, and 2016 MacBook Pro GPU issue rectifications to Sierra. Along for the ride were Photos fixes, improved audio quality with Bluetooth headphones for FaceTime and Siri, and support for new installations of Windows 7 and 8 using Boot Camp on supported macs.

Monday's iOS 10.2 release included the TV app, redesigned and new emoji, Photos fixes, some user interface changes to Music, and more full-screen Messages effects.
