Haiko & John: Just check that you are actually using the NVidia driver. Just because its installed, doesn’t mean its in use! The system has a habit of defaulting back to the generic mac driver, which will give the above error.
If you don’t have an NVidia icon in the top bar (RH side), try “System Preferences”, at the bottom.
After over a year of stable operation, my machine is now refusing to boot with the web-driver. I have installed the right version for my macos version (17G65), but when I select it, the machine hangs during the boot. “Cmd+Alt+P+R” resets it to the default mac driver, where it boots, but without CUDA.
Since I only use it for video editing, and the edit suite requires CUDA, this means my mac is now a paper weight.
Someone needs to bang Apple’s and NVidia’s heads together, but I’m not holding my breath. Next stop may be to install boot-camp and Windows (shudder) just to be able to edit again…
