Hey, I picked up a 13" MBP today, and it's snow leopard disc was a drop in. When I go to install SL, I hold down my C button, I hear my disc drive speed up, down and repeat, and then my screen goes blank (I'm talking for 15 minutes), and the disc i/o just seems to continue. Upon trying to do an upgrade, I get to maybe a 5% and then poof, blank screen (this one I even let sit for an hour), and from that point my Leopard Install is nerfed (because derp some data was re-written). I'm new to Apple hardware, but I can tell that this isn't whats supposed to be happening, and my Leopard disc boots straight up to the install prompt, and installs. a.)Has anyone ever heard of this doing? I'm going to assume that it's just a defective disc. If theres some trick i'm not doing, please do tell. b.)The Apple store will replace this, right?
