try and shutdown, does it reboot? Thats what mine was doing. I'm pretty sure its due to the atheros driver in multibeast. I did the top one v2.0.1 and my system would reboot on sleep, shutdown, and restart (lol that one worked)
I reinstalled Sierra without the atheros driver and it worked fine. Than I set everything up and an hour or two later my audio stopped working. I got fed up and went back to EL Cap for now. Check out the thread that I started today, someone posted a Atheros kext that fixed his restart issue.
What did you guys use for audio in Sierra?? For 10.11 I used the script in the guide (audio_cloverALC-110_v1.0l.command) and that worked great. I tried the multibeast ALC887/888b but its not working now, it did for a couple hours but stopped.
