[Nut-upsuser] How to shutdown macOS / mac OSX from Network UPS Tools client - NUT

Hi,

I’ve posted my question on Superuser.com but not had any replies in 2 weeks, so
I guess no-one there knows anything about NUT.

https://superuser.com/questions/1441153/how-to-shutdown-macos-mac-osx-from-network-ups-tools-client-nut
<https://superuser.com/questions/1441153/how-to-shutdown-macos-mac-osx-from-network-ups-tools-client-nut>

I’m looking for help in shutting down my iMac on detecting a power failure while
running from a UPS.

My setup is an APC SMT750i UPS, powering two Synology NASs, an iMac, plus the
network kit (router, switch etc.). This is all fine.  (Synology runs a variant
of Linux plus NUT).  I have installed NUT (v 2.6.5) on the iMac (High Sierra
10.13.6) using MacPorts. One NAS is connected directly to the UPS via USB and
acts as the ‘master’ in the NUT network, the other NAS and the iMac are
‘slaves’.

On power failure, the master detects the state of the UPS and broadcasts it to
the slaves, which both receive it OK. The NASs both go into ‘safe mode’
correctly as they are configured to do. The iMac receives the state change OK
and repeatedly alerts the logged in user, but does NOT in fact shut down, as I
want and believe I have configured it to do.

I have followed all the advice I can find online, especially at:

There’s nothing NUT/UPS related in the /var/logs AFAICS
 
Thanks for any help or advice

Is your System Shutdown Plan to shut down using upsmon or using the script 
upsched-cmd?  In upssched.conf you do not have a line

  AT LOWBATT ups at ... EXECUTE lowbatt

and in upssched-cmd there is nothing to shut down the system.

Have you tried typing the command "/sbin/shutdown -u -h +1" directly? 
Does this
perform a shutdown?

Joe,

Roger has a good point - the SHUTDOWNCMD should work as long as the master
system waits for the "OB LB" state, and doesn't shut down early
(say, at 30% battery remaining, but the UPS waits for 20% before declaring LB).

I have never used a Synology box, but I vaguely remember them not using the NUT
LB state. (That might have been covered in one of your links, but I haven't
had a chance to look through all of them.)
