Thanks. Unfortunately this no longer works on sequoia; you first have to run "spctl --global-disable" in a terminal and then - within a few seconds - go to Privacy & Security and select the new option in the popup menu (which was not available before). See also https://news.ycombinator.com/item?id=41184553. That's what I meant by "tricks". And even though there are apps which still didn't work. But fortunately I still have a Mac with an older OS version which I'm not going to upgrade.
