I have just puchased an AirPort Express. I have connected it to my current network so I can use airplay with Itunes to play music to my stereo. I have 2 MacBook laptops. One of them see the speakers and can play music but the other one cannot. The second mac is using Itunes 11.01.(and has all my music on it) I know you can't use 2 computers to simulataneously send music to the speakers but even when Itunes is not running on the mac that works, the other one still cant see the speakers. I have gone into the Itunes preferences to select 'allow itunes audio control from remote speakers' The window also says 'itunes is not paired with any remotes' and the 'forget all remotes' button is greyed out. I cant seem to get past this. Restarting Itunes, the mac and the Airport Express have made no difference.
