Once the downgrade and reversion to a prior release has complete, you can manually copy over any of the changed or new files that you made earlier, otherwise just be on your way. The same applies to revert to OS X Yosemite, Lion, or OS X Mountain Lion from OS X El Capitan.

So if you were running OS X Mavericks prior to installing OS X El Capitan, and you chose that date and OS, the Mac would reboot to OS X Mavericks.

Downgrading can take quite a while, so be sure the Mac is plugged in to a power source and don’t interfere with the process.Īfter the downgrade from OS X El Capitan is complete, the Mac will restart and boot back to where it was before at the date you selected, including whatever the OS X version was at that time. Once you’ve started the restore and downgrade process, you should be ready to wait for several hours, depending on the size of the backup being restored, the speed of the disk, and the speed of the Mac.

How to Downgrade OS X El Capitan Back to OS X Mavericks, Yosemite, or Mountain Lion with Time Machine Essentially what you are doing with this method is restoring from a prior Time Machine backup of a prior OS X install. You should also manually copy any new files or important data or documents that have been created from the date of the last backup from the prior OS X version and now, since you will lose those files in this downgrading process. Without a Time Machine backup to revert to, this particular approach won’t work.īefore getting started: You should finish a new backup before starting this process. This relies on having a recent Time Machine backup made of OS X prior to the Mac updating to OS X El Capitan. You can use this approach to downgrade to OS X Mavericks, OS X Yosemite, Mountain Lion, or Lion, directly from OS X El Capitan, assuming you have a backup from one of those versions.
