BioShock on an Intel Mac

I'm trying to figure out whether BioShock will work on my Macbook. It seems from what I've gathered that the specs are too high, but the specs that I've read on the internet seem to indicate it should work. I downloaded the demo and got the following error message: Incompatible video card has been detected. Intel GMA x3100 OpenGL Engine.

I have made no video card modification.

These are my specs: Mac OX 10.6.3; 2.4 GHz Intel Core 2 Duo; 2 GB. (If you guys need more info, let me know.)

The rest is my video specs:
Chipset Model: GMA X3100
Type: GPU
Bus: Built-In
VRAM (Total): 144 MB (Game specs say I need 128)
Vendor: Intel (0x8086)
