Firmware Password Frizzle!
So, I inherited this iMac late 2012 and used it until this happened… Something wanted me to set a EFI boot password so I did and it doesn’t work anymore. Another forum said the keyboard changed to US but alas that’s where I live! I swear I remember what I typed in but it doesn’t work anymore! I need this to be able to boot into a usb or recovery (witch asks for password when recovery is started) because I am a tamper monkey and love to develop on Mac. I have tried all the boot-combos and ram removing but it seems the mac ignored the boot combos! I have called Apple and took it in but they said I need a receipt but I don’t have it! (I SWEAR I DIDN’T STEAL IT BTW) This is the ONLY Mac I have and I NEED IT TO WORK!!!!! Please help me I can’t stress more than I am! This is my last resort!
