The CrossTie of this game will Install the game into crossover and create a shortcut into the Crossover Menu.
With F4 you can switch to full screen and windowed mode. Full screen can give white bars on the side (because of the resolution of the game), so if this is the case on your system you can choose to play it windowed or accept the white bars on the side. I am certain in not to many updates of Crossover this is fixed in the Mac Driver.
Have fun!
