Hi there, I have an old iMac G5 that I want to bring back to life. Unfortunately I've lost the install DVDs and the internal hdd is wiped clean so I'm kinda stuck. I know I could just buy a used DVD from ebay but I refuse to spend money on something I already bought. There must be a way to burn an install DVD from a downloaded dmg file but how? I have a MacBook Pro and a Firewire HDD. There must be a way!!?
