just a bit of feedback: I've used groff for years now with Mac OS
without any Mac specific problems I think (currently I use 1.19.3 but
it was OK previously, too). what I've seen frequently is, that equations
are not correctly rendered if the Mac postscript/pdf-viewer (`Preview')
is used: `Preview' (or rather the Mac pdf-rendering machine) is known
to be a bit buggy. so, if you produce postscript output with groff and
either open this directly with `Preview' or first convert it with
the ghostscript utility (`ps2pdf'), in both instances you'll get a
display which is to a varying extent corrupted (mostly in equations).
the same files look fine when viewed with `gv', `xpdf', or `acrobat'
(and print fine, too).

I understand that this is not your current problem, but just in case 
you've not noticed this one.
