Darktable mysteriously stopped working on me yesterday. I tried restarting my iMac, deleting and re-installing darkable and finally after going through some forums I tried running through the terminal:
open -a darktable
LSOpenURLsWithRole() failed for the application /Applications/photo programs/darktable.app with error -10810
chmod +x /Applications/darktable.app/Contents/MacOS/darktable
I also tried
chmod +x '/Applications/photo programs/darktable.app/'
I have tried with several versions of Darktable and am beginning to think it has nothing to do with Darktable and something to do with MacOS...
