GTX 970 under OS X 10.10.x and all updated NVIDIA drivers produces this error:

cuCtxCreate: invalid source

The problem is that current CUDA is NOT compatible with the NVIDIA GPU web drivers.
To make use of CUDA use an older version of CUDA.

USE:
GPU driver: 343.01.02f03 till 343.02.01f01
CUDA driver: 6.5.25 Nothing after will work currently - Dec 26)

Just join to thank you for this post !
I confirm I am on 10.10.1 running 343.02.01f01 (released this week I believe)
I got to 6.5.3something and hit same message as you did.
Reinstall the 6.5.25 and it works great.

Thanks again !

Just an update. I have installed Yosemite 10.10.2 and was required to install NVIDIA’s new WEB Driver 343.02.02f01. I am still using the CUDA Driver 6.5.25 mentioned above and Blender Cycles is working just fine.

Recap:
OSX version: 10.10.2
GPU driver: 343.02.02f01
CUDA driver: 6.5.25
CYCLES WORKING!

MacPro 3,1 (Early 2008)
MSI GTX 970 GAMING 4G

Cuda driver 6.5.46 now works with the latest GPU drivers for OSX.

Take care

Cycles doesn’t render with GPU. Just empty render window. I’m rendering just a simple small box.
