Run very stable with CrossoverGames on iMac Alu 2.4 ghz, 24inches 2Gb memory. Full resolution and high rendering options. Now I am in 1/2 of game, once had crash- due to overheat probably. Generally I am satisfied, however there is one problem - rotations on the map using mouse does not work, or works extremely slowly. This can be a little annoying, maybe somebody has a solution how to increase mouse speed ?
