Back up your Mac
It's a good idea to back up your Mac first, especially if you're installing a beta version of macOS. Beta software is software that is still in development, so some apps and services might not work as expected.
Add an APFS volume
- Open Disk Utility, which is in the Utilities folder of your Applications folder.
- In the sidebar, select your existing APFS volume.
- Choose Edit > Add APFS Volume from the menu bar, or click in the Disk Utility toolbar. These options are available only when an APFS volume is selected.
- Type any name for the new APFS volume, then click Add:
- Disk Utility should now show the new volume in the sidebar. The new volume will also appear in the Finder, as if it were a separate disk. You can now quit Disk Utility.
Install macOS on the volume
Choose an installation method:
- To install a beta (prerelease) version of macOS, enroll in the Apple Beta Software Program and follow the installation instructions on the program website.
- To install a release version of macOS, you can use macOS Recovery. The keys you press at startup determine which macOS is installed.
When the installer opens and you're asked to choose where to install, click Show All Disks, then select the new volume.
Switch between macOS versions
After installation is complete, you can use Startup Disk preferences or Startup Manager to quickly switch between each macOS:
- Choose Apple () menu > Startup Disk, then click and enter your administrator password. Select the volume that you want to use, then click Restart.
- Or press and hold the Option key during startup. When prompted, choose the volume that you want to start up from.
Keep the macOS on each volume up to date
To find the latest updates for each version of macOS, check for software updates, then start up from the other volume and check for software updates again.
