But for what it’s worth, here’s a list of free GIS-related software I’ve run across that claims to come in a Mac-compatible version (no GPS-related software). From what little I’ve seen, there’s far less GIS-related software for OS X than Windows, or even Linux, and that’s unlikely to change soon. Unfortunately, since I don’t have a Mac, I don’t spend a lot of time looking for Mac-compatible software. I get emails all the time asking about free GIS software for Mac OS X.
