Does anyone have info about where one could acquire a Grok program for MAC?

A strange program on a strange server?

You mean Grock Tunnel right? Grok is a programming language so I don't know why you'd ask that here.

AFAIK the only version of Grock Tunnel still around is the version in Virtual Hypnotist, and AFAIK Vhypno only works on Windows(and only properly on older version too.)

Maybe WINE would work?
