From PC to Mac - Alcohol doesn't work

I tried to burn The Sims for the Mac on my PC, to give to my sister, using Alcohol 120%.

As .dmg s are unrecognised by Alcohol, I had to fill in the Image File Format Settings - of course i just left them as they are, I don’t know enough to mess around with it.

The CD i then proceeded to burn didn’t work on my PC, but since it’s meant for the Mac i didn’t worry about that. However, it also doesn’t work on the Mac - it doesn’t recognise the data or something.

Can someone please tell me if there is a program that will easily allow me to copy .dmg files on the PC so they can be read on the Mac?

Thanks very much for helping

BTW I have a Matshita DVD-Ram UJ-802S, if that’s any help
