Thanks a lot, Warheck!
and btw, here are some screenshots of Mac's IVAN + mini guide from me:
1. Download BOXER from here
2. Download DOS version of IVAN here
3. Install BOXER
4. Open BOXER
5. Drag the IVAN DOS version to the 'Import New Game' section
6. Click 'Browse your games' section, notice now you got IVAN game in it.
7. Voila, play IVAN on mac
So far it works great with my standard MacBook Pro i7, the only let down of it is the game's frame-rate got significantly slower than the PC version.
