what do the numbers under the disc version 1.0 mean
I need to format my mac back to factory but only have the mac os x install disc. I found a set of the discs on ebay with identical information on the one disc that I have except the number under "version 1.0"; mine says Mac OS version 10.6.1 Disc version 1.0 2Z691-6517-A; the discs on ebay say Mac OS version 10.6.1 Disc version 1.0 2Z691-6674-A and applications install disc has 2Z691-6673-A. Will the discs that are on ebay work for my computer? Thanks
MacBook, Mac OS X (10.6.8)
