@Lorys89 I used Sanity Check to see what was wrong with my config.plist. I made the necessary corrections, the system is starting normally, but before the opencore menu appears, this appears: No schema for adviseWindows at 0 index No schema for advise KeyMErgeTreshold at 8 index No schema for Applevent at 3 index could you help me please

@Hervé I add the flag using propper tree, save changes and reboot. but, when in the system I was checked the boot args and igfxonln=1 disappear.
