Orbi app loaded on M1 iMac is a problem

In my zeal to have my RBR750 mesh system sorted out, I added the Orbi app to my iPhone and my M1 iMac 24". On the phone, the app works fairly well, just a few idiosyncrasies, but installing it on my iMac immediately started a Denial of Service Attack

from my iMac – or possibly through my iMac. (yes, I was forwarned that it wasn't verified for use on Macs) – I removed the app from my iMac.

After sorting my Mesh System out and getting solid connections between Router and 2 sattellites (adding wired back-haul connections between the devices and the main switch was the cure), I decided to test out the Orbi app and installed it on the iMac again. Same attack – so no device level maintenance on the iMac.

In both cases, Netgear Armor blocked the attack. Kudos!!!
