>I'm also glad it exists but have never figured out how to use it on MacOS
Same here. I just downloaded V4 to see if there was any improvement from last time I tried to use it* Open app, Select 'Add to Library' --> spinning beachball of doom
delete the ~/.config/darktable directory, to give me a clean start...
* Open app. App opens in a weird window the full width of my screen but only half the depth. I try to resize the window. It won't rezise, even though I get resize arrows when hovering over the corner. Finally manage to make it usable by hitting the fullscreen widget.
* Try 'Add to Library' again. This time it allows me to select my photos archive folder. I see there's a tickbox marked 'Recursive' so I click on that as I have subfolders in my photos archive. I can't select the box. Then the spinning beachball of doom starts again...
* Force quit
* Delete app.
Life's just too short to mess about with an app that hangs twice, requiring a force quit, before I've even managed to do a single thing with it.
