No question is stupid, but my answers often are.
I never know if I have installed all the drivers, as I don’t really know what is needed.
I threw the kitchen sink at this, and don’t know what I might need to further install.
Here’s the output of the darktable cl test:
darktable -d opencl

These are all tests on a Parallels Mac host, using a Manjaro Linux Gnome client.
I get the same results on a VMware Host or a Vbox host.
Running darktable on the Mac Catalina OS OpenCl is active. I have not done any testing of this version 3.2.1 on the Mac yet. Previously on darktable 3.0.1, I had so many crashes that I got more done using the Vbox install without OpenCl.
I’ll probably do some more testing on the MacOS native install and see if anything has improved. It’s one of life’s little mysteries !
