A few days ago I sat down with all my little discs and accessories prepared to do a reinstall of Mac OS X on my Macbook. I sat my install discs (version 10.4.6) that came with the laptop by my side and stuck disc 1 in. While I was waiting for the first disc to complete my husband sat down next to me apparently without looking down first. He crack my disc 2!! After a bit of a freak out I went and did some dearching to where I could buy replacement discs. After a day or two of searching and double checking I resigned to just buy the Mac OS X install discs for version 10.4.8 Today I got those discs and put in the first one. I restarted and held down C while I waited. The install screen came up and I clicked continue. After a second the little screen popped up and said it could not be installed on my machine. I tried to reset my machine 3 more times only to get the same message. Am I doing something wrong? Can I not install these discs because it is not the version my laptop came with? Could it be that since I installed disc 1 of the previous version that it will only except disc 2 of that version and nothing else? Any help would be appreciated. I'm without a computer for school until this is fixed.
