How to uninstall the macOS Sonoma beta

The macOS Sonoma beta is tantalizing — until you find a show-stopping problem with your workflow. Here's how to go back to macOS Ventura.

At least tell us you backed up your Mac before you installed the macOS 14 beta. If you didn't, then the odds are that you'll be best off sticking with macOS Sonoma instead of trying to downgrade.

That's because downgrading requires you to wipe your Mac entirely. So you could do that and then reinstall your apps and documents, hoping that everything is in iCloud, but at best it would be slow.

Even if you do have a backup, you're not going to switch to macOS Ventura in five minutes.

But if you must downgrade from the macOS Sonoma beta, the most straightforward way is to erase the Mac, and then start from scratch in Recovery Mode.

Choose Options, then click the Continue button that appears
