At first the freely-distributed versions of HyperCard shipped with authoring disabled. Early versions of Claris HyperCard contain an Easter Egg: typing "magic" into the message box converts the player into a full HyperCard authoring environment.[12] When this trick became nearly universal, they wrote a new version, HyperCard Player, which Apple distributed with the Macintosh operating system, while Claris sold the full version commercially. Many users were upset that they had to pay to use software that had traditionally been supplied free and which many considered a basic part of the Mac.
