 On May 9 , 2006 , Cyan Worlds and GameTap announced at the Electronic Entertainment Expo that Myst Online : Uru Live would be returning in the holiday season of 2006 . The GameTap version did not require any physical purchase : all the game content was downloaded through GameTap , which was subscribed to for a monthly fee . A major reason for the resurrection of the game was the fan support . According to GameTap 's vice president of content Ricardo Sanchez , " One of the reasons [ GameTap was ] so attracted to Uru Live is that it had this persistent group that kept it alive during the dark days of it not being a product . " Closed public beta testing of Myst Online : Uru Live began in August 2006 . A period of semi @-@ open beta testing lasted from December 12 to December 18 , 2006 , with an open beta beginning on December 20 . On January 18 , 2007 , it was announced that a Macintosh port of the game was being developed by <unk> ; a beta became available soon after . This coincided with the release of the first new Age , Eder <unk> . GameTap brought Myst Online : Uru Live online in February 2007 . On May 19 , 2007 , Myst Online made the move to episodic content releases , with each episode adding new Ages , puzzles , and a plot continuation . It was also released for Mac OS X , the first GameTap game for the platform .
