Easiest thing is to boot from your bootable backup, but:
- Press F1 at Clover Boot Menu to show help screen. F11 will reset NVRAM
- But I’m not sure if that will fix the problem
What changes were made to Clover? Or to the /L/E folder?
If you remove OcQuirks/FwRuntimeServices, you must copy OsxAptioFix2Drv-free2000.efi into the Clover drivers folder.
Similarly, if you use OcQuirks/FwRuntimeServices, you must delete OsxAptioFix2Drv-free2000.efi.
However, OcQuirks/FwRuntimeServices are both outdated. If you are planning to switch from Clover to OpenCore, then OpenCore 0.6.3 should be used.
But a full bootable backup must be made before making any changes.
