Installing macOS 10.13.1
â— Back up your Mac.
Always back up your data and files before installing beta versions of macOS. If you have
multiple Mac computers, we strongly recommend installing on a secondary system. Backing up
files on a Mac is easy with Time Machine, the built-in backup utility.
â— Enroll Your Mac in the Apple Developer Program
Download the macOS Developer Beta Access Utility from developer.apple.com and run the installer. Follow the onscreen instructions to enroll your Mac.
