I am running OS X Sierra on a MacBook Air. I don't remember exactly how, but quite some time ago I installed CUDA on my Mac (I was a newb then, I didn't know I wouldn't be able to run it without an NVIDIA GPU).
So after installation I was always greeted by this box upon login:
I wanted to remove this and all other traces of CUDA from my system. I did
locate cuda and deleted all the files which seemed related to CUDA. There were some occurrences of CUDA in OpenCV and Homebrew which seemed useful, so I kept them.
The good thing is that I am no longer greeted by this message at startup, but I can still see the link to the
CUDA Preferences in my
System Preferences (see circled area on bottom left):
Every time I click on this icon,
System Preferences "quits unexpectedly". This means that there are still traces of CUDA left on my machine. How can I remove it completely?
