Description miivo 2021-11-09 17:21:53 UTC 
SUMMARY
On Mac OS Catalina and Digikam 7.3, cannot use Darktable as the default raw image import tool. 

STEPS TO REPRODUCE
1. Settings > Configure Digikam > Image editor > Raw behavior, and select "Raw import using Darktable." 
2. Double-click any .Dng raw file in my Digikam database to edit it. 

OBSERVED RESULT
The image editor opens up empty and never loads the image. 

EXPECTED RESULT
The selected .dng file in Digikam should be opened up in Darktable.

SOFTWARE/OS VERSIONS
macOS: 10.15.7 (Catalina)
Darktable: 3.6.1

ADDITIONAL INFORMATION
If I use the default "libraw" raw image handler in Digikam, it works fine.
I have tried to add /Applications/digiKam.org/digikam.app/Contents/libexec/qt5/plugins/digikam/rawimport/ to PATH, but no success. The RawImport_DarkTable_Plugin.so is found from this path.

Start digiKam with the debug variable active in a terminal and post the log when you try to load a RAW image. The procedure for creating the log is also described here for MacOS:

Here is the part of the log where DT editor is opened.

DarkTable doesn't start, but the created file exists
-rw-------     1 "user"  staff    1246 Nov 10 17:46 digikam.huYqMV

but the export file is not found "digikam.Edxier"


PS. I have similar problem in my Windows environment, but there DarkTable opens, but Digikam cannot import the file back, as the export file is not created.
