“After a couple of possible security exploits, I upgraded to High Sierra for my Mini running Indigo. The Gen5 Z-Wave interface initializes perfectly, but my Insteon Dual Band MODEM now requires the USB connection to be physically unplugged and ‘re-plugged’ when I restart the Mini, after the High Sierra MacOS install.
The behavior appears consistent and repeatable, so far. I’m using Jay and Matt’s favorite USB2 hub.
As long as restarts happen in my presence, it’s a minor inconvenience, but as a loyal contributing member of the user community, I wanted to report my experience and ask if anyone else has encountered something similar.”
