# Uninstalling OpenCore

To remove OpenCore:

  1. Remove OpenCore either from the USB or internal drive
  • You'll need to mount the drive's EFI partition, and delete the EFI/OC and System folders
  1. Reset NVRAM (opens new window)

WARNING

Note that after you remove OpenCore, your Mac will no longer boot and show the "prohibited" symbol. Be ready to install an natively-supported version of macOS before you uninstall OpenCore.

  • This does not apply to native to native Macs just using OpenCore to achieve features like AirPlay to Mac and Sidecar, but it is still recomended to reinstall macOS, after removing OpenCore, if using SMBIOS spoofing to enable Univeral Control.
