Hi, I've been using AuthorizationMBS with success in some areas, but I've noticed that a command I'm running doesn't run. Code is similar to this: dim a as new authorizationMBS if a.SimpleNewAuthorization then a.execute("/bin/launchctl",array("unload","/Library/LaunchDaemons/com.bodoni.server.plist") if a.lasterror<>0 then break end if Although there's no error shown, the service does not stop. This works from the terminal: sudo launchctl unload Library/LaunchDaemons/com.bodoni.server.plist I can't see anything in the console log that might suggest what's wrong. This is from the console log. AuthorizationExecuteWithPrivileges and AuthorizationExecuteWithPrivilegesExternalForm are deprecated and functionality will be removed soon - please update your application I've tried a couple of variations, with and without /bin in the path and various launchctl subcommands such as disable, kill. Regards, Lee
