I remember that long time ago I used to connect my remote speakers through WIFI, using Itunes, IMAC and an Airport Express. Well, I am now trying to recreate the setup, but cannot find any settings in Itunes that would allow me to connect to remote speakers. Can someone please give me some pointers on how this is done? Alternatively, is there a way to control Itunes on my IMAC with my IPhone???? I would like to leave my MAC inside and listen to music in my garden and to be able to remotely change the music too (with the Iphone).
