Install macOS

Step 1

Step 1

Open the Utilities menu and click Disk Utility.

Step 2

Select your system drive and click Erase.

Select Mac OS Extended Journaled or APFS and click Erase. Don't select APFS if your Mac doesn't support APFS.

Close Disk Utility if you used it to erase your system drive, then click Continue.

Step 3

Select your system drive, the drive to install macOS on, and click Continue.

Step 4

Wait 35-45 minutes and click Reboot when the installation is complete. Then boot into your installer drive using the previous instructions.

Patch macOS

This is the important part. This is the part where you install the macOS Patcher files onto your system. If you miss this part or forget it then your system won't boot.

Step 1

Open the Utilities menu and click Terminal. Type patch and hit enter. Make sure to select the model your drive will be used with. Then select your system drive from the list and copy and paste the name.

Step 2

Wait 5-10 minutes and reboot when the patch tool has finished patching your system drive. Then boot into your system drive and setup macOS.

You can now use the latest version of macOS on your unsupported Mac. Thank you for using macOS Patcher.

Restore macOS

If you've switched to a new Mac or just want to remove the macOS Patcher files from your system, you can run the restore tool from your installer drive.

Step 1

Boot from your installer drive by holding down the option key when booting and selecting your installer drive from the menu. Then select your language from the list.

Step 2

Open the Utilities menu and click Terminal. Type restore and hit enter. Make sure to select the model you selected when you last patched. Then select your system drive from the list and copy and paste the name.

Step 3

Select wether you want to remove system patches or transparency patches. You can choose to remove all system patches or the APFS system patch, if you have it installed. Don't remove the APFS system patch if your Mac doesn't support APFS.

Step 4

If you selected to remove transparency patches then you can remove the hybrid mode patch or the flat mode patch.

Step 5

Wait 5-10 minutes if you selected to remove all system patches, then reinstall macOS. If you selected to remove the APFS system patch or a transparency patch, then you don't need to reinstall macOS, and you can boot back into your system drive afterwards.
