I'm pretty sure that I have done some testing with VServer on Monterey. But I've recently updated to 12.1 beta.
a) The AppleScripts can't be opened at all: The document “STOP” could not be opened. Script Editor cannot open files in the “Script” format. http://www.valentina-db.com/bt/view.php?id=9030
b) How do I stop the server with the stop_me.sh shellscript? It does like nothing. Doing a "sudo launchctl" directly in Terminal also does nothing at all. Does nothing means that the server is still running after executing the script.
