Im running a Macbook Pro 2.16GHz Core 2 Duo model, 3GB RAM, and I tried downloading the Catalyst Mobility version 7.9 required to run Quake Wars under XP, but the compatibility checker says I do no have a compatible video card. I mean, its an X1600, so it should work. I installed the Catalyst 7.8 because I found a downloadable version of the driver, but you cant get the new driver from ATi, only the compatibility checker. Anyone know where to get the Catalyst Mobility version 7.9?
