OSX 10.11.4: CUDA 7.5 cuInit() fails with

New to CUDA so please bear with me.

I installed the OSX 10.11.4 Web Driver followed by the CUDA Toolkit 7.5 toolkit. Then tried one of the samples but get a driver initialization error:

cudaGetDeviceCount returned 35
-> CUDA driver version is insufficient for CUDA runtime version

Other forum threads about this error always point to the NVIDIA driver. But my driver is the latest available:

MacBook Pro (Retina, 15-inch, Late 2013)
Hardware specs: https://support.apple.com/kb/SP690?locale=en_US&viewlocale=en_US
NVIDIA GeForce GT 750M with 2GB of GDDR5 memory and automatic graphics switching
NVIDIA WebDriver: 346.03.06f01
CUDA Toolkit 7.5.27 (reported from System Preferences)
XCode 7.3 (7D175)

Here are the short steps to reproduce after installation:

cd /Developer/NVIDIA/CUDA-7.5/samples/1_Utilities/deviceQuery make
/Developer/NVIDIA/CUDA-7.5/bin/nvcc -ccbin clang++ -I…/…/common/inc -m64 -Xcompiler -arch -Xcompiler x86_64 -gencode arch=compute_20,code=sm_20 -gencode arch=compute_30,code=sm_30 -gencode arch=compute_35,code=sm_35 -gencode arch=compute_37,code=sm_37 -gencode arch=compute_50,code=sm_50 -gencode arch=compute_52,code=sm_52 -gencode arch=compute_52,code=compute_52 -o deviceQuery.o -c deviceQuery.cpp

mkdir -p …/…/bin/x86_64/darwin/release
cp deviceQuery …/…/bin/x86_64/darwin/release
$ ./deviceQuery

Did I miss something??

More environment details:

$ clang --version
Apple LLVM version 7.3.0 (clang-703.0.29)
Target: x86_64-apple-darwin15.4.0

Cuda compilation tools, release 7.5, V7.5.26

^^^ V7.5.26 differs from what’s reported by System Preferences | CUDA

Also, what seems odd is System Preferences | CUDA reports “No version found” for the GPU Driver Version. Does that indicate an install problem?

Is my environment supported?

Thanks in advance!

Hi, I am having the same issue. On the same configuration. Is there a way to make it work?

Hi, exactly the same problem. Further, CUDA system reference says my GPU driver version is 10.11.5 (346.03.06f01), which is the newest one right now. Any thought about it?
