I’m trying Plex again, only this time I’m going the whole hog and have unplugged the ATV3 and Mac Mini and dropped in the ATV4 from the other room so I have no choice.
I don’t know if it’s day 1 jitters (as it loads up my library for the first time) but it doesn’t feel as snappy as I expected (compared to how quickly the ATV3 loaded Netflix). Even Netflix itself doesn’t feel quite the same, although it’s possibly all in my head.
If this goes well I might snap up a new 2017 model ATV (ATV5?) and drop that in the lounge room and retire the MacMini from HTPC duties. I’m looking at setting up OSX Server when High Sierra hits and playing around to see what it can do for me.
