And after ALL these have been tested and found nothing (because my Mac-mini has no extra hardware, or Mal-functioning hardware) and my file-system is perfect, and I have no login items at all) and I even took the liberty and run a few malware-searching facilities (MalwareBytes and friends) AND FOUND NOTHING!!!

Still, every morning My Mac looks like it auto-restarted itself, The zillion volumes on my external drive are re-mounted (whereas I dismounted them in the evening) and all my apps are closed.

What gives????

I would expect such essay to go a little beyond the most blunt tools, and at least enumerate the MECHANISMS that can cause auto-restart.

I found in the Preferences panels (Energy) a place where you can schedule auto wake-ups, sleep-cycles, restarts etc. (none)

I know that auto-updates of the OS may cause a restart - but I have them turned off.

What can be the cause?

My MacBook Air auto-restarts when I forget to shut off... CandyCrush before closing the screen for the night.
Maybe you have a program running, that causes the auto-restarts ?
