cannot see another airplay destination?
Started the day using airplay to stream to another older mac using system 10.6.8 and itunes 11.4 with good sound system connected. It then just disappeared.
Main mac is using 10.10.3, itunes 12.1. See both Macs on ethernet network and WIFI. See both ways the iTunes libraries and can share them. JUST CAN"T STREAM either way.
MacBook Pro (15-inch Early 2011), OS X Yosemite (10.10.3)
