Porting code to a mac

[ZUCCOLA]

	As odd as the following may seem, we have a few programs
	that are very simple graphical programs that run on sgi,
	and an E&S330. They are not graphically intensive or 
	computationally intensive and our silicon graphics,and 
	E&S are put to better use for the majority of the day.

        Has anyone ported E&S code or gl code to a mac (C of course)?
	If so I was wondering if you could give a few helpful hints.


				Thanx in advance,
