Sorry for the odd title. My laptop has not been seeing much mobile use lately. I mention that because it would occasionally act oddly after returning to my home network after use at other locations. It never bothered me, I simply rebooted.
Now, I will reboot when it seems something is amiss – as one does – and the computer will run fine for a few minutes, then do an apparent full power down hard reboot on its own. I then get this cryptic error message:
After that, it seems to run fine. I leave it on all the time, and wake it from sleep when I need to use it.
Not sure if this is related, but I ended up doing a full nuke n pave based on Apple tech support suggestion. A little while ago, this computer got into a mysterious reboot loop; it would run for a few moments after log in, then reboot on its own, ad infinitum. I ended up managing to boot into safe mode and called Apple. Fortunately I had a CCC clone to restore (Time Machine failed) and all was good until very recently.
Does this “double reboot” sound like reason for concern?
