One last step, we need to install any patches for your Mac.

Open up the OpenCore-Patcher app (Probably still in your Applications folder if you installed OpenCore with the package and upgraded macOS), and you will see a button available: Post-Install Root Patch.

Click that button, and OpenCore will search for aplicable root patches (Graphics Driver, Bluetooth, USB, etc.)

Once all patches are found, click on "Start Root Patching"
