Though not supported by Apple, I would like upgrade the RAM in my January 2008 MBP to 6gb up from 4gb. I have 3 questions: 1. With my vintage of MBP can this be done? 2. If yes, I assume I have to buy a 4gb and a 2gb ram sticks. So where and what memory should I buy? (supplier, speed, spec, etc). Please be as specific as possible. 3. Also, for someone who has already done this, have you encountered any issues, problems, system failures, software conflicts? I use MS office, VMWare Fusion, Firefox as well as itunes and Safari. Thank you.
