I use rehabs config.plist for hd520 and now my laptop restarts immedtly with old config.plist i got kernal error. I did backup on my old config.plist but when i use it it restarts not with kernel panic same as rehans config.plist. Is there default config.plist so i can back in previous state i try looking in efi backups foleder is empty.
