Apple Guide not only provides the user with help text on-screen, but also walks the user through the procedure. The Mac would ask the user to perform an operation, and an invisible red crayon (called the Coach) would appear on-screen. Should the user desire more information (if a term, for example, was not presented clearly enough), a Huh? button was (sometimes) on hand for that very purpose. Apple Guide does not exist in Mac OS X, to the chagrin of newbies.
