Alright so I downloaded Mac OS X 10.5 from my colleges computer department. When It was downloaded it was split into 12 zipped files that when unzipped create 12 .dmg files of size 650mb. After unzipping I am trying to find a way to properly burn these files. When I go into Disk Utility and select the first .dmg file it says the cd-r (700mb) I am trying to burn to is not large enough. I think it is trying to burn all 12 .dmg to one disc. If i place the first .dmg file in a different location from the rest of the .dmg files it does not burn and instead gives me an error saying it can not locate files 2-12. Any ideas or solutions?
