[QUOTE="chscag, post: 1815078, member: 46727"] No problem asking here. As for the EFI password locked logic board, it's doubtful that you will be able to use it without removing the password lock. Older model logic boards were easier to remove the password lock, but newer models require special equipment only possessed by Apple. If the logic board is by chance from an older model iMac (2011) you can probably remove the password lock. I'm going to let you do the googling to find the solution rather than post it here though. Let us know how it turns out. Good luck with it. [/QUOTE]
