Hi, A bit newer to the MAC community so be gentle. I have a MacBook Pro with iTunes 10.4.1. Just bought and installed a Marantz 5006 receiver with AirPlay. Trying to connect the two together but the AirPlay Icon is not showing up on my Mac?? I also have an iPad and have downloaded the Remote app and can control iTunes but again, no AirPlay icon. I've read a bunch of threads in this forum and others that all talk about 'hacks' for non-AirPlay enabled devices but the Marantz receiver 'should' be locked and loaded to go. Any thoughts? Much appreciated.
