I want to update the OSX 10.4.11 in my 15" MacBook Pro(2.16 GHz Intel Core 2 Duo) to OSX 10.5.7. I bought the disks on eBay several months ago and am finally getting around to installing. I insert the disk into the drive, choose English as the language and then click install. Immediately, a window tells me the OSX cannot be installed on this computer. The disks are for a 15 inch MacBook Pro. One has Mac OS Install DVD printed on it and the other reads Application Install DVD. When purchased, I was under the impression these disks would work. Am I doing something wrong, did I inadvertently buy the wrong disks or just get burned?
