From its wikipedia entry:
The initial Macintosh port was done on a Macintosh Plus
computer using the Lightspeed C compiler. It was a hybrid
port in that many of the low-level operations were passed
on to QuickDraw instead of using the internal bitmap
code. The application did not conform to the Macintosh
user interface guidelines as it took over the entire
screen. The initial version used either available serial
port as the communications channel. A later update of the
port could use either ethernet or serial communications.

Here it says a port to Macintosh-Plus was done in two weeks.

Does anyone know more about MGR, particularly on the Mac? That page has
the source for MGR 0.69, but there's no mention of the Macintosh in it
(aside from comments about how it was supported on older versions...)
I got it working once under FreeBSD back in the 4.x days.
It wasn't particularly notable, or at least didn't leave much of an
impression; it presented a pretty "standard" (and primitive!)
graphical experience. I believe it was monochrome, with amber
on black.
I don't know anything about it on the Mac, I'm afraid; I suspect it
probably ran in a Window under Finder, but that is pure speculation.
