Re: [Avid-L2] Mac Nvidia/CUDA drivers

Sounds reasonable. The rift between Apple and Nvidia has made this harder than it needs to be.

Michael,

If you stop after your Step 2, and ignore the available update, is CUDA functioning? If so, I'd stay there. You are not likely to see significant improvements going further.

There are a few OS-Cuda combos that don't work because the Cuda updater doesn't recognize the specific OS build number. It is possible to get stuck at an OS build number that Cuda will never recognize even though it is technically compatible. There is a fix (you can edit the list and add the specific build). If you are using a Cuda version that should be compatible with your OS version, you should research this fix.

nVidia's release notes for each version of Cuda tell you what OS is compatible. There is a "terminal" version for each major OS release and this terminal version is generally compatible with all earlier versions of that OS. For instance, your Cuda version is compatible up to 10.13.6.

Cheers,

That makes a lot of sense, John, thank-you. But when I actually follow those steps, I wind up back where I started:

1. manually uninstall CUDA, reboot
2. Install an older CUDA driver from before my OS release date (410.130, from 2018/9/19), reboot
3. CUDA panel now offers an update. "Install CUDA update" and reboot.
4. Now the CUDA panel tells me 418.163 is installed, but an Update is required, and the "Install CUDA Update" button is greyed-out again. Very frustrating.

Any other suggestions certainly appreciated!

Thanks,

You are correct. It won't work if your CUDA driver is too new.

Uninstall your current CUDA driver.
Install one that pre-dates the release of your installed operating system.
That should work. It will alert you if you should be running a newer CUDA driver.

Not in my case, unfortunately.

I installed the web-driver, then the CUDA driver, as recommended. After running for a couple days, it seemed like that was causing some hard crashes, so I switched back to the OSX stock driver.

After reboot, the CUDA control panel then tells me an update is required, but also says "No newer CUDA Driver available" and the "Install CUDA Update" button is greyed out.

I'm guessing the CUDA driver I have installed is too recent to be compatible with the OSX Nvidia driver, but the CUDA control panel doesn't know how to roll back...

I wonder, if I manually uninstall everything except the CUDA control panel, will it be able to download the right driver? I.e. if I uninstall all the following files:

/System/Library/Extensions/CUDA.kext
/Library/Frameworks/CUDA.framework
/Library/LaunchAgents/com.nvidia.CUDASoftwareUpdate.plist
/System/Library/StartupItems/CUDA/

Thanks,
