Do you have upsd and upsmon running as daemons on the Synology DSM?
Does the NAS shut down (and restart) correctly when wall power fails?

Is the Mac protected by the same APC UPS as the Synology NAS?

Do you have upsd and possibly upsmon running on the Mac?  What does 
command

    ps -elf | grep -E "ups[dms]|nut"

report on the Mac?

>From the NAS, can you execute commands such as

    upsc UPS at Mac ups.status

Does upsmon.conf on the NAS contain a MONITOR statement for the Mac? Do 
you propose shutting down on LB or after a time interval: in other words, 
do you need upssched?
