Home Sharing turning off on Apple TV ???
I just got a new iMac (hoo-ray!). My iTunes library is on the iMac, and I have Home Sharing turned on. On my Apple TV, I can see and play movies from my iMac iTunes library. So far, so good. But after watching a movie for about 30 minutes, Home Sharing on the Apple TV turns off by itself. The Apple TV no longer shows my computer as connected to the Apple TV. I think (but am not sure) that my iMac has gone to sleep and drops the Apple TV connection.
What (and where) are the configuration settings to prevent this from happening? I have tried various settings on the iMac in System Preferences > Energy Saver, but I still have the problem. I am on OS X 10.10.5.
Thanks
iMac, OS X Yosemite (10.10)
