<p>I don't think you'll see anything in Geany's logs - it isn't even launched by macOS in these cases.</p>
<p>The Console app isn't a terminal - it's a log viewer on macOS (you can find it under the Other folder in the launchpad). You can open the console app, then double-click a file in Finder and see if it says something interesting regarding Geany.</p>
