A port of Mac-on-Linux to OS X, by Sebastian Bastix. Mac-on-Mac is
capable of hosting Mac OS 9 (at least) and early OS X, while running
on Panther (Mac OS X 10.3.x) as the host OS. Included is another
variant of MoL for OS X which seems to produce VMs.

1st and 4th download are applications to run directly.
Both comes with source and (some) documentation. Both have Alpha
versions? MoM comes with a full release and some extra files which
seems to patch in sound. MoM's source is are still available from
[Sourceforge][1].

DISCLAIMER: I have not tried to compile any of this stuff. I have just
un-loaded the files here to other more compile/programming talented to
explore. Use it after your own mind. And if there will some brewing
most welcome to share!

Note: The 2nd screenshot above, is by "[AphoticD][2]" and was taken in
2017. It depicts MoM running Mac OS 9.2.2 and Puma Mac OS X 10.1.x, on
Panther 10.3.9. ? AphoticD, writing about his experiences with MoM,
noted:

Compatibility
Architecture: PPC (Carbonized)

Mac-on-Mac and MoL started under OS 10.4.11/G3 500MHz. No further
testing was done.

The Mac-on-Mac startup panel will launch OK on Mac OS X 10.4.x but
cannot launch the VMs. MoM requires at this point in time, a Panther
10.3.x Mac OS X with Panther's X11 installed to act as the window
manager for launching the VMs.
