Yes, I went to reformat my computer and my Mac OS X install disk does not work. There's already no OS on there, stupid me... Should have let the Mac validate. There's not allot of scratches on the disk, but it's not working. It gets stuck on Disk 1. But does Apple Warranty the disk or will I have to buy one? If I do, I will just buy the box set with iLife and iWork. But it says does not ship to Jan, how long will that be? IDK, if this is in the correct section. I don't have my glasses and could vary easily skipped over an section.
