This question already has an answer here:

"Your Mac restarted due to a problem."

System.log showed boot time as 17:19 and the last message before was 17:13 but things had been working in the five minutes before the restart.

Six log files had file dates after 17:13, but five of them had NO messages before the reboot. (The other has timestamps only in raw integer format)

So how do I look for clues to what happened between 17:13 and 17:19 ?

It's a Macbook Pro 2012 refurb still under warranty (purchased January) but the RAM and SSD were transferred from an older machine.

  • If I understand correctly you restarted the computer and it seemed normal, with the exception of that popup? – the eels have eyes Sep 13 '17 at 1:22
  • Seemed normal before it crashed, too. – WGroleau Sep 13 '17 at 21:15
  • Check for the Shutdown Cause code in your log and see: Shutdown cause and sleep cause numbers listed/explained anywhere? – kenorb Sep 26 '17 at 15:35
  • Well, I am going to check the other question, because "check the log" is not a very useful answer to "where is the log?" – WGroleau Sep 27 '17 at 8:49
