How to unlock MacBook EFI/Firmware lock
Hey all, I bought the 2015 12" MacBook Retina model back in early 2016, though in 2020, it refused to boot and just today I got signal on my monitor as the LCD is broken with a padlock meaning that its Firmware Locked, I do have purchase proof and I do have the apple ID that the macbook was used with. Do I have it to an Apple Store in order for them to remove the lock and do I have to pay for it?
