a 2011 imac 21 inches and with a 2010 macbook air.
after replacing the efi chip machines staring taking longer to boot up.
and some times when power bottom has been press machines doesnt respond.
thats my note for this threath i will tray to get more into brute force wich is a lil complicated....
The longer boot time is because you need to clean the ME region in the chip itself. Otherwise its gonna be hella slow. Why? CPU and mac EFI ( BIOS or whatever ) , make a handshake so if your chip is not cleaned out that region it means you have a corrupted efi for other mac computers.
