That would suggest that the IDE can't write its settings file in /Users/username/.config/agk/ so it can't record that it's already updated. Can you check that location and see if there are any files there and if they have been updated recently. It is a hidden folder so you may need to change some settings to view it.

Yeah that's what I'm seeing, unfortunately I can't see any way forward to improve it further. I tried the latest version of Geany and it too seemed to be better than our most recent version but not as good as our old versions, similar to the version I attached above, so maybe there is hope that they can figure out what has happened. Can you try downloading it from
here and see if you experience the same problem with that?
It all seemed to change after we updated to XCode 10 with the 10.14 SDK, but reinstalling XCode 9.2 which we used for the old version doesn't seem to have any improvement in the final executable, so maybe that's just a coincidence.
