or, more specifically: A relative of mine has a iMac with OS Leopard or 10.5.8. He does not, however, have internet access. So, for x-mas, I was thinking of downloading (purchasing) some software for him, and ship it on a cd-rom or dvd-rom. As I use a PC (Dell laptop with Blue-Ray dvd burner), I have done some searches on this and they all seem to revolve around bootable discs, disc images and/or are 4+ years old. As I'd like this to run without to much issues, and I can't test it beforehand, what should I be keeping in mind for this process? Or is it so simple as just burning the .dmg file and shipping it off? thanks!
