Uninstall OpenCore Legacy Patcher

Removing OpenCore Legacy Patcher can involve the app, root patches, the OpenCore bootloader, and NVRAM. Plan each step so the Mac can still boot when you finish.

App removal is not a full undo

OpenCore-Patcher-Uninstaller.pkg removes app utilities. It does not undo OpenCore or root patches by itself.

Bootloader removal is risky

After you remove OpenCore, a newer patched macOS may no longer boot.

Keep recovery media

Prepare a bootable USB with OpenCore or a natively supported macOS installer first.

Download the OCLP uninstaller

Download OpenCore-Patcher-Uninstaller.pkg from the download page when you need to remove the app, LaunchAgent, and PrivilegedHelperTool. That package does not revert root patches or delete OpenCore from EFI by itself.

  • Match the uninstaller version to the OCLP build you installed when possible.
  • Revert root patches before you remove the only working graphics or WiFi path if you still need that Mac.
  • Keep a bootable USB ready before you delete EFI/OC.

The manual uninstall steps

  1. Step 1

    Revert root patches

    Open OCLP, go to Post Install Root Patch, and choose Revert Root Patches. Monterey and later support snapshot reversion. Big Sur may require reinstall.

  2. Step 2

    Remove the application

    Use OpenCore-Patcher-Uninstaller.pkg from the download page to remove the app, LaunchAgent, and PrivilegedHelperTool.

  3. Step 3

    Remove OpenCore from EFI

    Mount the EFI partition and remove the EFI/OC and System folders. Do not delete the whole EFI folder because it may contain Windows or Linux boot files.

  4. Step 4

    Reset NVRAM

    Reset NVRAM after removing OpenCore to return boot variables to a cleaner state.

Before removing the bootloader

After removing OpenCore, your Mac may no longer boot newer patched macOS and may show the prohibited symbol.

Have a bootable recovery path

Prepare a bootable USB drive with OpenCore or a natively supported macOS installer before removing the bootloader.
