MacBook Pro a1286 EMC 2417 Board NO 825-2915 B Hi Guys. Can you tell me where the EFI chip is on this MacBook Pro’s motherboard please. thanks Nathan
You cannot change the EFI chip. The ME region is tied to the CPU. Replacing the chip will cause performance issues and crashing.
Best thing here is for your customer to visit an Apple Store with proof of ownership and some ID. As Apple does have a very special tool which they can unlock the hardware password lock. If on the other hand the system was iCloud locked then you’ll need to have them unlock it from ‘Find My iPhone’ app or if they have a second Mac from within iCloud services ‘Find My Mac’ Replacing the EFI is not a good idea for this kind of issue. In the end you’ll have messed it up enough other services won’t work correctly as it’s security key won’t be intact any more (ME Region).
