Apologies in advance if I should be able to find the answer to this question... I am considering purchasing a friends 2008? Macbook 5,1...Aluminum...looks brand new...it's 2.0 ghz C2D with a 160gb drive and 2 gb ram. If I do, I want to increase the ram to the max...OWC, who I have used before, says 8gb will work, while Crucial says 4gb. Who is correct? From what OWC states on their site, even my 2009 Mac Mini with the 2.0 C2D can accept 8 gb (currently at 4 gb)...even though I distinctly remember that it could not when I bought the ram back then! seems like a worthwhile upgrade...particularly from 2 gb any feedback would be great. thanks!
