I have a Mac Mini runing 10.11.4, latest versions of iTunes and also the server app. There is an external HD attached that houses all my Movies/TV Shows. Because it is serving data to my 4th Gen Apple TV, itunes is always open. However I have been noticing some strange behavior. When I have remoted into the machine I am noticing that iTunes is actually playing media back on the machine itself. I have muted the machine so I am not hearing it in the background, but I cannot figure out what is causing the media to play. The only thing I can think of is my Logitech Universal remote, but it is not paired with the Mac Mini. I am not using the Apple remote app,nor is there any remote paired with iTunes Does anyone have an idea as to what is causing this?
