Hello, I have to change the logic board on an iMac 17" 1.6 GHz model A1989 but only found instructions for the A1058 (same speed, same size). Does anybody know if they will do? I assume there won’t be much difference, maybe the shape of some components… I have successfully changed the keyboard of a MacBook Air so I should be OK. I hope! Thanks, Paul

At the risk of me sounding stupid, are you sure the model number is A1989? I believe your machine’s EMC number is 1989, which would correspond with Model A1058 (all these cryptic numbers!!!). If so, the A1058 instructions are exactly what you are looking for to repair your machine! This is my assumption because even their newest 27" iMac is model number A1311, and they go in semi numerical order with their model numbers…so they’re nowhere close to reaching that number yet. I hope this helps!
