itunes 12.1 can't find apple tv 1st gen-- help!
My itunes 12.1 (on macbook pro running yosemite) suddenly stopped reading the apple tv. I tried restart the apple tv & itunes, no luck. Tried disconnecting the macbook from the apple tv to reconnect, but now itunes cannot find the apple tv at all to read the connect code to set up again to stream. The documentation speaks of an icon (there isn't one, just the airplay icon, & it does not find apple tv either-- but I never used that before in any case). Preferences & devices show nothing, Multiple restarts don't help. The apple tv can connect to the itunes store & play stored stuff (it is a first gen); apple support doesn't have a clue (I got switched multiple times, & was told they had no idea what I was even talking about. Frustrated-- can anyone help me figure out how to get this working again? It was perfectly fine, then suddenly it was gone & I can't get it back.
MacBook Pro, OS X Yosemite (10.10.2), 1st gen apple tv
