Problem installing Cuda 9.1 on MacOS 10.13.6 - cuda driver version insufficient for cuda runtime version

Hi All,

I’m having some trouble getting the CUDA samples to run, getting the following error for “deviceQuery”
Any advice would be greatly appreciated!

cudaGetDeviceCount returned 35
→ CUDA driver version is insufficient for CUDA runtime version
Result = FAIL

My Environment:
MacOS 10.13.6 (MBP 2017)
NVIDIA Web-Drivers 387.10.10.10.40.105
CUDA-Drivers 387.178
CUDA 9.1 Toolkit
XCode 8.3.2
GPU Card: MSI RTX 2080 Ti - Connected through eGPU RAZER X

CUDA preferences window shows:

CUDA driver Version: 387.128 (no GPU Detected)
GPU Driver Version: No version found
pwd: /Developer/NVIDIA/CUDA-9.1/samples
