I have to use CDs to transport files in between PCs and Macs. Under 10.1, I would just get the disk ready as an MP3 CD and put files on it. Now that's not an option. I can't find any way to make a ISO 9660 CD under 10.2. Even when I make CD master images, it just picks MacOS Extended and no options for te file system. Is there any way to make it work without buy expensive CD burning software.
