Thanks for the tutorial! However, I'm not adventurous enough to take a chance. I live in NYC and was wondering if you could recommend someone who could do the job? New Jersey and Connecticut are fine. I'm willing to travel withing reasonable distance.
So far I've been turned up by all the mac Mac repair shops that I have contacted in NYC as nobody would consider to replace a mother board for a machine born before 2009 (mine was born at the end of 2007).
