SUMMARY
All options other than LIBRAW are disabled in 

STEPS TO REPRODUCE
1. Go to Preferences->Image Editor (Settings is called Preferences on Mac)
2. Click the RAW Behavior tab
3. In the "Always open the Raw Import Tool to customize settings" option, open the drop-down list
4. All options are disabled except for "Import Raw Using Libraw (default)", even though Darktable is installed.

OBSERVED RESULT
All options are disabled except for "Import Raw Using Libraw (default)"

EXPECTED RESULT
Default option and "Raw Import using DarkTable" are enabled since DarkTable is installed.

SOFTWARE/OS VERSIONS
Windows: 
macOS: Sonoma 14.5 (23F79)
Linux/KDE Plasma: 
(available in About System)
KDE Plasma Version: 
KDE Frameworks Version: 
Qt Version: 

ADDITIONAL INFORMATION
I checked the docs, and there was no mention of this being a MacOS limitation.  If so, the bug report should be against the docs and not the code.

Comment 1 Maik Qualmann 2024-07-31 04:28:31 UTC

If the Darktable is grayed out, the executable is not found via a Qt function.
What is the exact path to the Darktable binary on macOS?

Comment 2 Michael Miller 2024-07-31 10:58:40 UTC

Using the darktable.dmg for installation puts the binaries in /Applications/darktable.app/Contents/MacOS.

Comment 4 Michael Miller 2024-07-31 21:26:49 UTC

There's a minor bug in the PR.  The path for RawTherapee is:
/Applications/RawTherapee.app/Contents/MacOS  

The default MacOS file system is case sensitive.  I'll install the other raw processors and update the comments with the paths if they aren't correct.

Comment 6 Maik Qualmann 2024-08-01 05:51:19 UTC

I don't use macOS myself and only imagined it for RawTherapee. ((:-))
The executable files are in lowercase?

Maik

Comment 7 Michael Miller 2024-08-01 11:04:28 UTC

Yes, the binaries are all lower case.

I couldn't find an MacOS installation package for ART, and I don't have time to set up a build environment.  Sorry.

Thank you for doing this.  I appreciate it.

Cheers,
Mike

Michael,

Problem is fixed now with the 8.5.0 pre-release installer for Apple Silicon (arm64) ?

Thanks in advance

Thanks.  I've been using it in my Homebrew build for a while now.  It works well.  Thank you.

I marked the issue as resolved.
