Psst is a faceless application that lets you adjust/mute the volume of your Mac's startup chime. Double-Click "Psst!" in the Finder to adjust the volume settings.
Important: The method Psst! uses to change the volume does not work on every model! What it actually does: It simply adjusts the volume settings before shutting down and after logging in.
