Home Sharing: no libraries available
Using a 2013 MacBook Air MD760LL/A with iTunes. Trying to stream media to my 4k Apple TV but the orange "Computers" icon on Apple TV states "no libraries available" when I click it even though the Macbook Air is listed on my devices (same wifi network). Sharing and Home Sharing enabled in iTunes (entire library). Help - please advise.
