So heres a puzzle for you all. I have a 2007 MacBook Pro with a broken disk drive that only runs CD's but not DVD's. Its currently running 10.5.8 of Mac OS X. Wanting to update to Snow Leopard, I acquired a copy, then tried various methods to use an iMac at my disposal to help me install Snow Leopard onto the pro. After fooling the Mac Book Pro into thinking it was a Mac Book Air to use Remote Disk, failing to find a firewire cable that could tether the MacBook Pro to the iMac, and finally creating a disk image in cdr format using disk utility then copying it to a hard drive to then copy onto the Mac Book Pro, i was still met with a notification saying the cdr must be burned onto a disk for the macbook pro to read. Right back where i started. Any ideas on how to do this without replacing the disk drive?
