[MacSourcePorts]

Yeah I'm not sure how many ports have a Mac build but no Windows build but generally I find that most of these have a Windows port because everyone has Windows, a Linux port because anyone with a spare PC can run Linux, but no Mac build because either no one on the team has a Mac or "the person who did the Mac build left/disappeared" so I'm trying to be that person for everyone, to some extent.

But yeah if it can run on the Mac it can run on Linux and probably does. There's a few cases where it doesn't go the other way (Skin Deep uses OpenGL 4.3 and the Mac stopped at OpenGL 4.1, that sort of thing)
