I'm not aware of any programs myself which will read Apple Mac disks.  I would
also be very surprised to find any, since the Mac uses a constant linear
velocity disk format (and drive), where everyone else uses constant angular
velocity.

In short, a Mac disk spins at a slower rate when the head is at the outer
tracks, and faster on the inner tracks.  This means that there are more
sectors on the outer tracks, and fewer on the inner.  The density of the
information is the same (bits/inch or whatever) no matter which track you're
on.
