Thanks for updating the builds so regularly. Usually, I have no problems but this time I can’t run openCL.
I did a darktable -d opencl and got this output. It shows that the device is detected but dt still can’t implement OpenCL.

I usually erase the device lines in darktablerc and let dt rebuild but this time no luck. Would anyone have an idea what is happening please?

OK, I solved the problem but rather than erasing the previous post, I’ll give the solution I found.

  1. Erase .cache folder
  2. remove the 3 lines starting with cldevice_v5 in darktablerc
  3. run darktable-cltest . It seems to rebuild opencl and OpenCL becomes available but OFF
  4. In darktablerc find the line opencl=FALSE and change to opencl=TRUE

current 5.2.x bugfix build + Canon R1 and R5mII support by Adding new camera support in darktable / LibRaw / ExifTool – Pandas Welt + a couple of RF lensfun data from: Kameratrollet
+ AgX development version (A port of Blender’s AgX to darktable by kofa73 · Pull Request #19026 · darktable-org/darktable · GitHub)

darktable-5.2.0+73~ge936e03aa3_arm64.dmg (macOS >= 11.3)
darktable-5.2.0+73~g2cf0d2a68b_x86_64.dmg (macOS >= 10.14)

you might run it with an in-memory library via terminal:
/Volumes/darktable/darktable.app/Contents/MacOS/darktable --library :memory:
or use a separate config directory:
/Volumes/darktable/darktable.app/Contents/MacOS/darktable --configdir ~/.config/darktable_test

also keep in mind that if you don’t disable writing sidecar files these can be messed up

both packages are unsigned, you might need to allow execution via terminal: " xattr -c <path/to/application.app> "
