As a followup for whoever is interested, this unofficial port was usually called "HackQuake" and was compiled from source code that was apparently stolen from the web server of the developer "Crack dot Com". Unsurprisingly, it was not very well-optimized at all. It was leaked online far far before MacSoft's official Quake port was released (I want to say approaching a year?), so it was the only version of Quake that Mac gamers had for quite some time. I don't know much more than that about its history, though! BTW, the solution to the rocket/grenade lag was to replace your rocket or grenade .mdl file with one that had no particles (it was particle rendering in particular that caused major slowdown). Some obscure 90's Mac gaming history for you! ;)
