Mac pre-alpha now Live!

To those who pre-ordered and have a Steam Key, the Mac version of the pre-alpha is ready to play!

I bought a MacBook Air 13.3" last week, fired up Unity on it, and resolved all the major issues.  There are a few niggley little ones remaining.  But it plays well now.

Going forward the Mac and Win versions will be identical, they sharefrom the same codebase.
