I am a Mac Pro user myself, I LOVE my mac, however I use Parallels, which is a mac application that runs a copy of windows seamlessly with OSX (mac), no dual boot junk needed!, the windows apps load up just like they are mac products. It runs flawlessly, hell I even have a ton of other windows development apps installed that are just not out for OSX (mac) So I have best of both worlds!
I am running Windows 7 and OSX.

So there is no need for a mac version :D Problem solved. And to be perfectly honest I hate it when companies, especially very SMALL companies like the C2 guys, spread themselves too thin trying to do two version of the software, when the end result is: half the features, half polished, half stable product. It is always best to focus on one platform, build it up, make it better, faster and more stable...... This is why C2 is as good as it is right now, because they are focused on delivering a solid product to windows users.
Do I wish there was a mac version.... to be honest yes, but in reality I fully respect and understand why there is not and probably never will be. Like I said I would rather have a solid stable application like we have now.
Plus as I mentioned above Parallels closes that gap, and allows mac users the best of both worlds.
