Select " Restore From Time Machine Backup" and click Continue. Step 2: Select Restore From Time Machine Backup As the Mac boots up, press and hold Command + R key until you see the Apple logo.
If you backed up with Time Machine to an external drive, connect the external drive to your Mac and click Apple menu > Restart. Otherwise, you will lose the files after getting back to Sierra or other version of Mac OS. You should know that restoring a backup from Time Machine erases everything on your startup drive, so back up files that you have since the High Sierra upgrade to an external drive. If you have backed up your Mac with Time Machine before the macOS High Sierra upgrade, you can simply downgrade High Sierra by restoring the backup. It can delete system caches, logs, duplicate files, old files, etc. Note: Since macOS Sierra requires more space to run than High Sierra, after uninstalling High Sierra and reverting to Sierra, you can use FonePaw MacMaster (opens new window) to clean your Mac to get more space. The methods can also be applied to downgrade macOS Sierra, Mac OS X El Capitan and more. This post will introduce you three ways to downgrade macOS High Sierra to Sierra, Mac OS X El Capitan, Yosemite or earlier. If you have upgraded your iMac or MacBook to macOS High Sierra and don't enjoy it, perhaps because that some apps you rely on no longer work on High Sierra or your Mac runs slow after the upgrade, you can downgrade from macOS High Sierra and revert to the previous version of macOS or Mac OS X. Mac OS has been updated to macOS High Sierra. Updated on October 12, 2019: This macOS downgrading method is available for macOS Catalina to Mojave, Mojave to High Sierra, High Sierra to older version.
