I just upgraded to a 2018 Mac mini and everything has been great...except for bluetooth. I first noticed with my Magic Trackpad - it will only consistently work when plugged in via a lightning cable. If I unplug the cable it connects fine, but it will randomly stop tracking and start back up in half a second or so, making it unusable. The same trackpad works fine with my MBP. I then tried my Sennheiser BT headphones and the audio is choppy with the Mac mini visible line of sight within 3 feet of the headphones. I then tried my AirPods and they won't even stay connected, they just continuously drop then reconnect. Has anyone experienced any similar issues? Could this have something to do with a USB hub I am using? I'm going to do some more testing and try unplugging things, but this is quite annoying to deal with from a $1800 machine in 2018. This was a completely fresh machine, no backups used when setting it up.
