Following the release of beta 2 of iOS 10.2.1, Apple today began rolling out the second build of macOS Sierra 10.12.3 for testing purposes. This comes a week after the first beta of the future OS upgrade for the Mac became available. Both developers and public beta testers will receive the beta over the coming days.
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 mbedded@icloud.com 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 2 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.
