Troubleshooting Restart on Sleep

shooks · Jan 5, 2017

I'm having trouble with a restart on sleep after upgrading to 10.12.2. I had this a long time ago and solved it by disabling hibernate mode (set to 0). I checked and this is still set to 0.

Any help troubleshooting would be greatly appreciated!

Here's the log:

I've noticed this as well. The computer will restart when I leave it sitting for a few hours. I am guessing that it happens when it sleeps, but I haven't actually confirmed it. It is not that big of a deal because the machine restarts quickly, but it can be annoying.

FYI: I seem to have solved this by disabling Power Nap and Wake for Ethernet network access.
