I have it hooked up through Ethernet on my Mac Pro 5.1 OS X 10.11. Internet sharing is on.
If I restart and to connect to the internet sometimes I still can’t get the list of updates.
A couple of times the emote wouldn’t connect to the unit as well.
Restarting the unit and/or the Mac solves the internet and emote problems but not always notbeing able to see the updates
