I bought my aluminum MacBook last November and have not yet purchased Apple Care. The first time I had to bring my MacBook to the Genius Bar was last weekend when I began to see problems with my computer booting up. Turns out that the problem was my 1 stick of 3rd party RAM not matching up with the other original 1GB stick (currently have 3GB total) which was causing problems since the MacBook has integrated graphics and shares with the main memory, so the 2 sticks of RAM have to be the same kind. Apple didn't seem to care that I had installed 3rd party RAM. I was recommended (by the "Genius" I was with) to buy another 2GB stick from that same 3rd party to get up to 4GB so the RAM sticks would match and I could have the maximum amount of RAM. So for now, I'm using the stock 2GB (2x1GB) configuration until I can buy another one of those 2GB sticks to match up with the 3rd party stick I have so I can go up to 4GB RAM (the maximum my/any MacBook will take). The "Geniuses" didn't seem to care about the fact that I'm using 3rd party RAM, but would it conflict with my warrantee if I purchased and installed a 3rd party hard drive? I'm looking at a 500GB Seagate HDD (7200rpm; $140 on Newegg) and don't know if this will conflict with my 1-year warrantee or not. I want to purchase Apple Care in the next few months as well. Based on what I've heard, the $250 I'd have to pay for my aluminum MacBook is well worth it. What do you guys think about Apple Care? What experiences have you had with having to use Apple Care for your warrantee work? Feel free to share your personal experiences with Apple's tech support and Apple Care in this thread! I'm interested to see what you guys think!
