Problems on the Mac: Steam and VMWare Fusion

Two issues have arisen trying to play the game on a Mac. First, although now Steam downloads and installs the game on a Mac, you can't get beyond the initial game screen. Clicking on ANY of the buttons has no effect, but you can command-Q to quit the game. Also, about half the time, the game crashes to the desktop and never loads.
Second, using VMWare Fusion 7.0 (and earlier, as documented several times under the 1.3 discussion), to play under Windows 7 Pro 64, the game screen shows up with characters and active items like doors, but nothing else. Background is black, completely missing. Setting VMWare Settings > Display > Accelerate 3D Graphics to OFF fixes the display but cripples the game (and Windows in general) because the graphics are so slow.

First, can you tell us what type of Mac you're using, and what version of OS X it's running?
