Apple today seeded both developers and public beta testers with the third beta of macOS High Sierra 10.13.1 for testing on the Mac. This comes a bit more than a week after the second build was released to the same two parties. It also comes a day after the third iOS 11.1 beta was released.
To install the build, 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 High Sierra 10.13.1 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.
So far, there hasn’t been any noticeable changes spotted in the new beta but we’ll let you know if we find anything down the line.
macOS High Sierra includes the Apple File System to make using your Mac faster, Metal 2 with native VR support, updates to Siri including an all-new more human-like voice, autoplay blocking in Safari for ads, and support for external GPUs you may wanna hook up to your machine for heavy workloads or intense games.
