Hello: Apple doesn't officially support it but I'm looking to get 2 * 8GB memory sticks for my macbook pro. First, I wanted to know what companies would be good to buy ram from. I found them from Corsair (Amazon 1 and Amazon 2) but some people are saying to go for different brands like OWC. Crucial also has it. Second, does this void my memory? Could apple say that a problem with the video card or logic board is due to 3rd party memory and refuse service? Thanks!
