It’s actually quite easy to drill down to the binary locations…
In Finder, go to the relevant containing app.
- Select “Show Contents”
- Drill down until you get to the folder containing the binary. Now for the fun part…
- Drag’n’drop the folder over to the “Favourites” area
- Close Finder
Open darktable and do your stuff. Once you get to where you define the binary location and start the process, click on the folder that you had dropped earlier. You’ll then see the binary!
