Back up your Mac

Skip this step if you already backed up your device.

Please note that you are about to install beta software. Always back up your important data and files to the cloud or an external drive. If you own multiple Macs, we recommend installing the beta on one that you use less frequently.

Backing up your Mac is easy with Time Machine, Apple's built-in backup utility.
