If you don’t have such a backup, you need a backup of your data that won’t include the operating system. If you have a Time Machine backup from before you updated macOS you can use that – but make sure to back up any new data that you won’t want to lose when you wipe your Mac. The problem with Time Machine is that it makes a complete backup, including the operating system, so you would just reinstall the version of macOS you are trying to revert from. Normally our advice would be to use Time Machine to back up your Mac, which is a great solution if you have a Time Machine backup from before you updated macOS. You will therefore need to make a backup of anything you don’t want to lose. Most of the processes for installing an older version of macOS mean you will need to wipe your Mac.

You may find you can’t install an old version of Mac OS X on a new Mac because the drivers for the hardware in your new Mac simply don’t exist in the old software, so it can’t run. Now for the bad news: It is unlikely that your Mac will be able to run a version of macOS or Mac OS X that is older than the one that was installed on it when you bought it. First you need to confirm that your Mac will be able to run the version of macOS or Mac OS X you want to install.Īs a guide, expect your Mac to be able to run any version of macOS or Mac OS X that was supported when that Mac launched, and any that were released in the few years immediately following your purchase.
