%%%After Discussing already that the blender does not see the graphic card as computing device, I did more tests. I was able to run Adobe CS6 mercury engine, which is also cuda based, without problems. Also Cuda-Z Application does recognize the graphics card and delivers results out oh their performance tests.
I have installed the latest Cuda driver: 5.0.36
see also Blender 2.6 Bug Tracker item #32534%%%

%%%OSX does not come with precompiled CUDA Kernels, you have to install the CUDA Toolkit 4.2 first. %%%

%%%What does that mean? To run Cycles with CUDA in OSX I have to install the Toolkit? I thought the toolkit is necessary for developers.%%%

%%%The Toolkit is needed to compile the Cycles CUDA Kernels. We pre-build and bundle them for Linux and Windows, but not for Mac OS. You can download it here: http://developer.nvidia.com/cuda/cuda-downloads%%%

%%%o.k. its finding now the cuda graphics card. When I set the Device to GPU compute the following error message pops up:

Compiling CUDA kernel ...
gcc: No such file or directory
CUDA kernel compilation failed, see console for details.

both in Experimental and Supported feature set.
The screen stays with a dark checker board

%%%You need the GCC compiler as well for your operating system. %%%

%%%works now., but its weird if you only want to use a software, that you have to install all of this tools ;-(%%%

%%%Our Mac maintainer says its problematic to bundle the kernels.

Closing the report. %%%

%%%It was my decision to ...

not to give advantage to Nv/cuda vs. AMD/openCL users
not to deliver something i cannot test myself

Easiest solution: get cuda kernels from graficall builds and copy to the /scripts/cache
To be always on the newest cuda revision ( may vary with OSX used ): get Cuda-Toolkit + cmdline-tools from Apple and compile kernels yourself.
