OpenCL is not available in 2.4.2 (it was available in the previous version)
When I open the settings, it looks like on the screenshot. OpenCL did work before (in version 2.4.1).
Also, before that, darktable 2.4.2 asked me about a performance test or something (I didn't save the text and I guess it's a one time event) and I answered "Yes". Could be related.
By the way, I can't select 2.4.2 in the Affected Version field here in redmine. There is no such option.

Perhaps it is this issue:
Try to start darktable with "-d opencl" and check output.
The problem disappeared as soon as I tried this. Then if I later launch it as usual (not from command line), the problem also doesn't reproduce anymore. However, before I tried to launch it from command line (`/Applications/darktable.app/Contents/MacOS/darktable -d opencl > darktable_log.txt 2>&1`) it was reproducing 100%. So, something was permanently changed when I tried to launch it from command line.
