After a MAC sw update, which took my MAC Mini to MAC OS X 10.6.3, I can not run the sample programs.
I uninstalled CUDA by deleting /usr/local/cuda, /System/Library/Extensions/CUDA.kext, /System/Library/StarupItems/CUDA as well as the /Developer/GPU Computing directories and reinstalled everything.
I have and still am using 2.3.1a driver.
Make went fine with some warnings but when I test:
CUDA Device Query (Runtime API) version (CUDART static linking)
There is no device supporting CUDA.
Device 0: “Device Emulation (CPU)”
CUDA Driver Version: 2.30
CUDA Runtime Version: 2.30
CUDA Capability Major revision number: 9999
CUDA Capability Minor revision number: 9999
Also, when I try to launch CUDA Visual Profiler, I am getting “Unable to initialize CUDA” message.
