I'm pretty sure my old ATV2 could access home sharing without actually bringing my Mac mini out of sleep. I've not touched any settings on my Mac mini, so it has to be down to the ATV4. So now, every time I brush over the computers app, my Mac wakes up fully and then I gave to manually sleep it afterwards otherwise it stays on all the time. As I don't want my Mac awake all the time, I want to get the set up right again so that the ATV4 can access the home sharing files whilst the Mac mini remains slept. Is anyone else having this issue and managed to resolve it?
