The Shut Down desk accessory was a System 7.5 Apple Menu Item that could instantly shut down your Macintosh. It came in handy when you were too lazy to switch over to the Finder to access the Shut Down command under the Special menu; or when you wanted to drive your roommate crazy by placing an alias to the Shut Down utility in his Startup Folder. There's nothing worse than a Mac that starts up and instantly shuts down ... except for a Mac that doesn't start up at all. Incidentally, there's a new utility that can do that, too. It's called Mac OS X beta.
