Yes. I am not using iCloud. All photos on my old iMac can be accessed and viewed on my Apple TV. This does not happen with my new iMac. Apple TV does pick up music and TV shows from my new iMac, so that part of sharing works. I just can't get the Photo library to show up on the Apple TV. I don't know if this is an IOS, iTunes or Photos issue. It works with El Capitan 10.11.6; iTunes 12.8.2.3; Photos 1.5. It does not work with my new system which is Mojave 10.14.5; iTunes 12.9.5.5 and Photos 4.0
When I go to iTunes "sharing", I can't select my photo library (as it is greyed out). I can only select specific folders. Very frustrating as it works so well with my old machine..
