Hello - I have a white unibody macbook, purchased in January of 2010. I think I would like to upgrade to Lion, but I think I need more RAM before doing so. I currently have 2gb. I read this section, but it was a bit over my head (perhaps that in itself should tell me I can't do this myself). I think I can figure out how to put new RAM in, I'm more concerned about how it might negative effect the whole system - the mentions of kernel panic on the other thread frightened me. So, here are some of my questions - 1. How much should I put in? 2. What RAM is compatible with my system? 3. Are there any problems I should expect? 4. Is there anything I need to do prior to upgrading RAM?
