As of 10.9 or 10.10, Apple removed the ability to execute cronjobs or schedule the computer to shutdown from the login screen. You have to be logged in in order to do either of these. This is problematic in a computer lab environment where everybody signs in with their own account, and logs out when done. As such, none of my computers are shutting down in the evenings. So... anyone know if there's a plist or global setting somewhere where I can toggle this behavior and re-enable it?
