Hey, fellow Mac users. Here's what I did last night:
1. Downloaded free 7-day trial of CrossOver Games from CodeWeavers.
2. Installed on my iMac (3.0GHz, 2G RAM)
3. Downloaded Steam client (for windows)
4. Opened CrossOver, ran the installer for Steam
5. Signed up through the Steam interface, and downloaded DEMO for Civ5
6. Successfully PLAYED a few turns of the demo!
However, there are some graphics glitches, as you can see in the screen shots. The fog is all graphite hexes, the terrain textures are a mess, and I think the UI is confused about the resolution, since it's only using about half the screen.
I plan on spending a few hours this evening trying to figure out what's going on. I'll also try to take some actual screen shots for you all
EDIT: PS - I forgot to mention that there is a semi-serious problem when launching the demo:
There's a little window that pops up where you choose to run under DX9 or DX10 (or something like that).
After choosing, the dialog box flashes a couple of times, and resets.
So I click again... and again... and again... eventually the screen goes completely white (no dock or anything) except for a large black box in the upper left of the screen.
After about 20 seconds the Main Menu for the Demo pops up.
