I really wasn't going to weigh in on this topic, I get enough of "not Mac compatible" from someone at work but...
Don't let Apple keep you from using the best control system for model railroading that has come out in a long time.
I don't think it can be said any better than that. There are options to run the software on a Mac, heck even I don't have a supported OS on the PC I use for RP, but VirtualBox fixes that, if not a bit slower than running natively. I could probably say more but I'm too tired to think of anything else.
Perhaps, if we have anyone running non Winblows systems we can create a couple of guides for getting RailPro software to run on various OS's using virtualisation software; I know the Linux crowd will have to do that forever, native code RailPro software for Linux is just not going to happen.
Dean, what flavour of Linux you running?
