Mac Mini restarts on wake from sleep with 10.12

[MattA]

Hello all,

My 2011 Mac Mini has recently developed the habit of restarting itself every time you try to wake it from sleep. It only started doing this recently over the past few weeks, but nothing about the system has changed. It's really frustrating, and I'm not sure what the cause is.

Short of a reinstall, is there any setting in the system where it causes a restart if there are certain criteria met, and if so, can we shut it back off?

The Mac in question:

Mac Mini 2011
i7 2.7Ghz (Sandy Bridge)
AMD 6630M
750GB 7200 rpm HDD
16GB memory

Any help would be greatly appreciated.

I'm sort of in the same boat as you. since I upgraded to Sierra from Mavericks, sleep/hibernate became an issue. I've tried many things but not much luck yet. Currently if the displays go to sleep I can press any button on the keyboard and the mini wakes. If the mini hibernates, it no longer recognizes keyboard inputs or the track pad so it wont wake. Pushing power button does nothing and you have to hold it down for 10 seconds or so to re-boot.

First, test in Safe Mode. If not happening there, then it's one of your login items or a launchagent or launchdaemon.
