Republic Commando crashing my Mac

I've been playing a "Best of Star Wars PC" collection lately, and all of them are running fine on my Mac (runs through boot camp, windows XP) except for Republic Commando. I install it, I get to the menu screen, I start a new game and once it fully completes the loading screen it freezes. But it doesn't just break the game, it breaks my whole mac. I can't go on either of the windows of mac paritions, they start up then freeze. I need to do a safe boot on my mac parition to end it.Its on the same disk as Battlefront and Jedi Knight II so the disk isn't the problem. And the system requirements are above recommended, so I don't have a clue what to do.

Has anyone encountered this problem before?

It's a mac, what else do you expect?

common problem iirc. The game cant run with some shaders enabled, its weird I know. I forget the exact name of them but before you start the game you need to disable them in the video options.

Sorry for the necropost, but how should I go about to disable shaders?

when the game loads got to the options manu and set shaders to disabled or off they dont need to be on otherwise the game wont run.. also you may need to adjust mouse sensitivity manually on the mac as the settings in-game are poor and there poorly setup. btw not to spoil anything but pm me when you start the 2nd main mission tell me what you think.
