So far we've put over 50 hours of time into just getting Meraki stable and to do the bare minimum.
Our company size is increasing significantly and our reliance on this automation that Meraki offers grows with it.
We've not been able to use Meraki in a repeatable fashion since the start and as a result all our efforts have gone towards "making it work" and not improving efficiencies through automation.
As a result of all these issues in service and feature delivery we've decided to migrate over to JAMF Pro.
I too am seeing a similar behavior on the newly purchased M1 MacBookPro and 24" iMacs.
This is just a few of the issues. I've literally wiped and reinstalled MacOS 4 or 5 times on each of the devices just to get Meraki to behavior somewhat normally.
Is there a compatibility issue between Meraki SM Agent and MacOS 12.5, 12.6 or the M1 chip itself?
From our side quite literally all of our effort has been put into finding workarounds for things that are broken in Meraki. We've narrowed it down to the agent being the cause of most issues. Near 100% of the time normal commands that just require valid APNS works fine without issue but anything extra involving the m_agent immediately becomes hit or miss quite literally a 50/50.
This tool is expensive in a large environment, but does not behave like an expensive tool.
