I've been experiencing mysterious reboots on my machine and another 10.12 lab machine. I can't find any entry in policy logs, system logs, jamf logs, or anything like that. The machines will just be back at the login prompt, but not any reports of a bad shutdown or anything. I've noticed it's also only when I've walked away from the machine for a bit (lunch, meetings, etc). I can't seem to find anything that would be causing it. Any ideas where to look or what to look for?
