After I installed the last macOS updates in December it has been rebooting at random times when in sleep as per below:

Genius is suggesting you to reset the PRAM or the SMC without any idea of the source of the problem, leave him with a polite excuse (these religious resets are fixing bugs more than 20 years old when MacOS X was able to corrupt any of those components). – dan Feb 05 '18 at 19:30$ pmset -g logand paste the lines of the log from shortly before the last known good sleep through shortly after waking into the unexpectedly-rebooted state? – pion Jan 31 '21 at 08:22
