Hello, Having a early 2009 Mac Pro (modified to a 5.1) with gtx-970, i updated from 13.3 (it was doing fine then) to 13.6 high sierra and updated the nvidia web driver to 387.10.10.10.40.122 and the screen does stay black.
It seems to toggle back to the OS X graphic card driver sometimes. Is there a a solution to this or should i simply wait for the next driver from nvidia?
