okay i think i get what you wanted, so you want to get the PC files of the skeletal bones reference and transfer it into your mac?
If you were able to find a PC to open the CD and view its files, and
if you emailed the .ma or .mb file from a PC computer to your email > so you can open it on your mac, that should've work...? correct? cuase maya files in PC and Mac should be the same.
if you're talking about changing the PC files on the CD to become Mac file, that beats me.
or maybe i'm just reading the question wrong >,<
