How to Uninstall macOS Sequoia Beta and Reinstall a Prior macOS

If you wish to downgrade macOS Sequoia beta to macOS Sonoma, Ventura, or earlier, you should put your Mac into Recovery Mode to do so.

Step #1. Boot Your Mac In Recovery Mode

  1. Shut down your Mac.
  2. Start your Mac in Recovery Mode.
    • If your Mac has Apple Silicon, press and hold the Power button until you see the "Loading startup options" message appear, then click "Options" > "Continue".
    • If your Mac is Intel-based, press and release the Power button, immediately press the Command-R key combination, and release them when you see the Apple logo.

Step #2. Delete the macOS Sequoia Beta

When your Mac is in Recovery mode, you will see a window offering four options, Restore From Time Machine Backup, Reinstall macOS Sonoma, Safari, and Disk Utility. What you need to do is use the Disk Utility to uninstall the macOS Sequoia beta from your Mac.

  1. Select "Disk Utility" and click "Continue".

  2. In Disk Utlity's sidebar, select the drive installed with macOS Sequoia beta.

  3. Click the Erase button in the toolbar, then erase your volume (keeping the format as APFS).

  3. Wait for the installation process to finish.

Step #4. Restore From Time Machine Backup (Optional)

Alternatively, you can choose the "Restore From Time Machine Backup" option to roll back the macOS Sequoia beta to an older version. However, it is worth noting that you need to have a Time Machine backup created on a compatible older macOS.

Here's how:

  1. Connect the drive with Time Machine backup into your Mac.
  2. From the macOS Recovery window, select "Restore From Time Machine Backup".
  3. Select your Time Machine backup disk, then click "Continue".
  4. Choose the backup file you want to restore, select your destination disk, click "Restore", and wait for the restore to finish.

How to Revert macOS Sequoia Beta to macOS Sonoma, Ventura, or Earlier

If you want to install an older version of macOS but don't have a Time Machine backup, utilize a bootable installer for macOS.

Don't have one? See How to Create a Bootable USB for macOS Sonoma, Ventura, and More.

Once you have your bootable macOS USB drive ready, follow the steps below to install macOS.

  1. Turn off your Mac.

  2. Connect your bootable USB drive to your Mac.

  3. Do one of the following:

    • On an Apple Silicon Mac: Press and hold the power button until you see the boot options window.
    • On an Intel-based Mac: Turn on your Mac, and as soon as you see a black screen showing the inserted bootable drive, press and hold the Option (Alt) key.

The Bottom Line

After reading this detailed guide, you should know how to uninstall the macOS Sequoia beta and reinstall your preferred macOS. As you can tell, the safest way is to disable Beta updates and wait for the official release of macOS Sequoia this fall. But if you want to revert from the beta to a previous macOS version, put your Mac into recovery mode, erase it with Disk Utility, and then reinstall your macOS or restore data from a Time Machine backup. If you don’t have a Time Machine backup, don’t worry. You can also use a bootable USB installer to install the macOS you want, but only if your Mac is compatible.
