I currently play the PC version of the game through Steam. That's all fine and good, but it's not my main computer I play on. That's because my main computer is a Mac, but since the game is coming out on Mac I'll want to have everything moved over there.

However on the preorder page for the Steam version of the game I'm only seeing a Windows icon. Is there no way to purchase the Mac version through Steam? Is there any way to purchase HW standalone for Mac when I have a Windows license? Would I need a separate Mac license to play the game at all? :S It is rather confusing and none of this info is really published anywhere. Any help is appreciated.
