I'm in the same boat as the pug... :)
I started using Construct 2 within Parallels 7 and it ran pretty well (newer 2012 MacBook Pro). But the opportunity came around to pick up a Windows 7 laptop so I have started doing everything on that now.
But I would never turn down a port of C2 for OS X. Never. ;)
But I would also rather see more functionality go into the current build rather than see Ashley do what some of the other tools have done and split their effort between multiple platform builds and see new functionality suffer.
