    If I install Xournall++[1], just opening the application will fail and MacOS will ask me to move it into trash. I am required to execute `xattr -c /Applications/Xournal++.app` to "remove quarantine".

    I just reinstalled and can confirm that I don't see anything in the System Settings as you say.
