SHUTDOWNCMD "/sbin/shutdown -u -h +0” in upsmon.conf on the Mac did the trick. Thanks! 

After power is restored, the Mac starts. 

What I wonder if the shutdown is done proper. Does the shutdown command use umount to prevent disk corruption?

I also have to find a solution for starting up upsmon when the Mac starts and also still open is the notification on the Mac. 

But thanks so much all for the steps so far. 


Kind Regards,

Rob
