You might want to save off the output of "pmset -g" before experimenting further - that way, after you find a solution, you can run it again to see what changed.

This page implies that the "sudo" and "-a" are not needed:


Also potentially useful, though I can't imagine it is changing different settings under the hood:


Alternatively, on 10.12 and 10.11, there is a "-u" option to shutdown:

     -u      The system is halted up until the point of removing system power, but waits before removing power for 5 minutes so that an external UPS (uninterruptible power supply) can forcibly remove power.  This simulates a dirty shutdown to permit a later automatic power on. OS X uses this mode automatically with supported UPSs in emergency shutdowns.

Let us know what works. (I have NUT set up on a Mac Mini, but we do not get frequent power outages, and the machine is set to wake up on a schedule anyway.)
