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.

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: https://networkupstools.org/ <https://networkupstools.org/> https://superuser.com/questions/1228972/how-to-automatically-launch-nut-client-at-boot-on-macos <https://superuser.com/questions/1228972/how-to-automatically-launch-nut-client-at-boot-on-macos> https://diktiosolutions.eu/en/synology/synology-ups-nut-en/ <https://diktiosolutions.eu/en/synology/synology-ups-nut-en/> What am I doing wrong?
