This is a Windows-only product. It is doing Windows API abstraction. They could, of course, get this running on an Intel-based Mac or Linux, but they would have to do a whole lot more API translation to get it working - and probably have to use Wine and X11 in the process. Quite a lot more work. I'm happy with it. I have Parallels. Now I can use just one VM for all my Windows testing.
