The problem is that Mac files are Apple HFS format which is not supported by
the MS-DOS Extensions. These can be read by direct sector access calls to the
device driver, but someone would need to convert the disc from HFS file
structure to something DOS could deal with. It is easier to use the Mac to
read PC files in HSG or ISO9660. I don't know of any direct access methods for
reading mac CD-ROM files, but I have read the data at the sector level through
the driver on a pc.
