Why does my HD work on another Mac but not on mine.
My MacBook Pro is in trouble thanks to me. I never back up my system and everything starting with my family and my family tree is on this HDD. If I put my HDD in another MacBook Pro exactly like mine then it works. I installed a new Optic Drive a fan Bluetooth cables new speakers new monitor and still having trouble now I ordered a used logic board that came with EFI password so thats no good.
Can I order another LB and still keep my HDD with all my information?
Please Help!
Thank you all
