Heres a direct download link for CUDA 418.163.) Older CUDA versions are available at Mac CUDA Drivers Archive.

Note: Theres been no Nvidia CUDA or Web Graphics driver updates for macOS Mojave or Catalina.).

All brand or product names mentioned here are properties of their respective companies.

After the reboot, I noticed in BOINCs Event Log that CUDA was NOT Present.

I was on CUDA Driver 8.0.71 here, as well and the Driver worked months ago before moving to TBars OpenCL App that Im on now.

All seems to be as it should now that CUDA Driver 410.130 is in place.

TL EDIT: Added Color for more clarity.

One other question.

Why is the Dual Xeon CPU System also NOT being shown as CUDA Compatible I thought all CPUs could use CUDA.

EDIT 2: My OS Version hasnt changed, on 10.13.6 Ver: 17G65 - 2018-001 Security Update.

For Sierra and High Sierra you need to use the Highest CUDA version.

Just keep Updating it in CUDA Preferences until it says Nothing Newer.

Dont connect them to a Monitor, use a GPU with at least 3GB of RAM, such as my 1050Ti.

The 2GB NV GPUs work fine as long as they are not connected to a Monitor.

See this, CUDA version 9.2, compute capability 6.1, 4096MB, 3550MB available Thats how much vRAM OSX uses Just to run the monitor.

You should have updated to a CUDA 9 driver back when Sierra first appeared.

It is different for the actual Apps, i.e., a CUDA 8 App will still work with a CUDA 10 driver.

You shouldnt even have a cuda 8 driver installed in H.S, much less ask why it doesnt work.

I dont think CUDA has Ever worked for CPUs, last time I checked it was strictly for nVidia GPUs.

I, therefore, was unable to go beyond 8.0.71 then.

On 10.13.3, I still made use of the 8.0.71 CUDA Driver to first Test the very old CUDA App that you created that I was also using on the Hackintosh.

It was then that you mentioned and highly recommended that I move to your OpenCL App, and I did make that change.

BUT, I still kept the CUDA Driver at 8.0.71.

Since then, I Upgraded 10.13.3 to 10.13.4, 10.13.5, and now 10.13.6 with Sec Update 2018-001.
