Following today’s release of iOS 10.12.1 beta 1, Apple has seeded developers and public beta testers alike with the first build of macOS Sierra 10.12.3 for debugging with a weight of 1.03GB. This comes just one day after macOS 10.12.2 made its way to the public, packing new wallpapers, Unicode 9.0 emoji support, and plenty of bug fixes.

As of now, only bug fixes and stability enhancements can be found in macOS 10.12.3, but we’ll update this article if something interesting is found. For those who make discoveries about the latest macOS betas, you can forward your sightings to and @MBEDDEDMaximum on Twitter.

To install the latest macOS Sierra 10.12.3 beta on your registered Mac, head over to the “Updates” tab in the App Store and check for updates. There, you’ll find the new build ready to install. Just click the “Update” button next to the macOS Sierra 10.12.3 Beta listing and restart your Mac. The process may take a little while, so be patient and don’t turn off your Mac manually if you don’t have to.
