The Amiga hardware is capable of reading and writing Apple II and
Macintosh formatted disks.  Whether or not any software exists
that allows this to be done, I don't know.  I doubt that it is
possible for a Mac with an IWM to read an Amiga formatted disk.

The IWM has a GCR data separator that looks for a sync bit every
byte.  This throws away timing information that would occur in an
MFM or RLL encoded data stream.  About five years ago I remember
seeing an article on reading Atari 800 disks with an Apple II.
As I recall some of this timing information might be recoverable
statisically, but not with certainty.

It is highly probable that appropriate magic software would allow
a Mac with an IWM to write an Amiga formatted disk.

Anyone know what the new Macs use for the disk controller?
