How to Downgrade macOS Mojave 10.14.2 to macOS High Sierra

Before getting started, you should note some things first:

  • Make sure you have already had a Time Machine backup of your Mac when it was at macOS High Sierra.
  • If your Mac came from High Sierra, the downgrade will be a tad easier.
  • If your Mac didn’t ship with High Sierra preinstalled, you will first have to create a bootable macOS Installer. To make it done, simply visit this Apple Support page.
  • Before returning to the previous version, you need to erase your Mac. So, make sure to fully back up your computer to restore it later.

Once done, proceed with the following steps to start the downgrade:

Step 1: Click on the Apple icon and then select Restart in the menu. Next, press and hold Command+R keys and make sure to hold them until your Mac reboots.

Step 2: Your Mac will automatically enter Recovery Mode. From there, click on Disk Utility in the OS X Utilities and click Continue.

Step 3: Choose the Startup Disk and select Erase tab at the top.

Step 4:  Enter the name for the file you want to delete. It could be something like macOS High High Sierra.

If your Mac is using HFS+, you need to select Mac OS Extended (Journaled) from the list. Select APFS if your computer is using APFS. You have to select GUID Partition Map, if it is Scheme. In the end, simply click on Erase.

Step 5: Once your Mac has been formatted, you need to quit Disk Utility from the drop-down menu to go back to the OS X Utilities selector.

That’s all! You have successfully removed the Mojave version from your Mac, and it’s ready to reinstall High Sierra.
