My machine is a Mac Pro MacPro5,1, with a 6-Core Intel Xeon and NVIDIA GeForce GTX 680. I'm running Sierra (OS 10.12.6) I have downloaded the latest webdriver from Nvidia, but after installing it and restarting, the system only recognises the default MacOS driver. I'm experiencing random crashes which appear to be graphics related. Nvidia support told me that a lot of people are having this problem and pointed me to this post which appears to have found a way of solving the issue: https://www.insanelymac.com/forum/f...-after-installingenabling-nvidia-web-drivers/ However I have no way of beginning to understand how to follow the steps outlined. It all seems like an alien language. I starting using a Mac in the early 90s because I wouldn't have to get involved with OS. Nvidia support told me to wait for a new release of their driver, but had no idea when this would be. In the meantime the frequent crashes are driving me nuts. Is there some kind person out there who can help?
