unspecified driver error on MacBook

[sgu]

Hi,
I have a MacBook with Snow Leopard and Geforce 320M. I tried to install CUDA toolkit 3.2RC but failed. I download and install everything as the “Mac OS getting started” guide. But when I tried to make and run the SDK example matrixMul, I got the following error message: “Runtime API error : unspecified driver error.”
Then I doubted that it is the driver. So I went to the System Preference and saw an icon of CUDA and an update button. I clicked it. Strangely, instead of upgrading the driving, it “downgraded” to 3.1 again. Then I run the same example, and got the error: “CUDA driver version is insufficient for CUDA runtime version”. How can I get CUDA running in my macbook? Thanks.

The toolkit 3.1 seems fine. But when I try to build the example and run the deviceQuery, I got a 0.0GHz for clock rate! Anyone can explain to me why?
