I have a 2.1Ghz white Macbook. I've still got around 1.5 years of Applecare left on it. I'd like to sell it, then buy either a unibody or older Macbook Pro with Applecare left. My first question: There's an extremely small crack on the top casing near the hinge. It's purely cosmetic, and the Apple genius couldn't even see it. Since Apple won't repair it, should I mention it? Second, I bought a Snow Leopard family pack. I have it installed on 3 computers right now - the one I'm selling, and two other ones. If I sell the computer, would it be okay for me to leave Snow Leopard on there, since I have a valid version?
