As far as support goes, the CFE core isn't really in active development right now though I address bugs as they are found. And putz with new things when I feel like it.
NeonBoomBox and QCar are more active right now in the Mac arena.
If you are a programmer, most of that is possible but there is nothing in the Mac world that does (or is likely to without other people getting involved) all that.Here's what I got and want to control, My Airride, XM radio, Cathodes(lights) Nav, OBDII, Video, audio, dual video output....to say the least!!!
