Hi..i have mp 2009 quad 2.66.. I usually go to macmall to have them install my additional hd...and graphic card.. but i was thinking about replacing my main hd for ssd. If i'm going to do that...how would i transfer my stuff to main drive...or better yet...how would even install snow leopard cd on it? I'm not sure if i know what i'm talking about because i never thought of doing except having someone install additional hd... please help me. thx.
