Following Monday’s release of macOS High Sierra, Apple today released the first developer beta of macOS 10.13.1 for testing on the Mac. 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 1 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.
Right now, it remains unclear whether there’s anything new in this build of macOS. However, we’ll let you know if there’s anything notable.
