My main develop Mac still runs 10.10, so I was not noticing this until now:
My app silently quits somehow early at start on a 10.11 system, with no message whatsoever. Console shows nothing, not even after I added System.DebugLog calls to App.Open and App.NewDocument.
But then I launched the app from the Terminal, by executing myapp.app/Contents/MacOS/myapp - and that did show the DebugLog msgs.
What’s up with them not showing up in Console under “All Messages”?
