Device Profiles Disappearing

[Gavin61]

Hi, hopefully someone will have a fix for this one.

We have >100 Macbooks enrolled in ADE > Meraki MX105 with various profiles for VPN, Wifi etc, we have the problem that Mac devices will lose their profiles, either becoming unmanaged or disappearing altogether.

Have tried reinstalling the meraki management by adding the device again, which didi not work, the only way I can get the profiles & management back is by migrating the user data to another MacBook, reformatting and provisioning the MacBook through ADE and then migrate the user data back!

This is very time consuming, has anyone seen this and have any ideas how to stop this happening or shortcuts.

Thanks Gavin

Your Apple push notification certificate hasn't expired has it?

Thanks Blake, no checked that, Apple MDM push certificate it's fine, but good shout, also checked there where no Geofencing policies that would have stripped the profiles.
Interesting if you go to one of the automatically assigned profiles say Systems Manager Sentry Wi-Fi, the affected Macs show that the profile is not installed.
I have found that this tended to affect older OS 12.6 Macs and upgrading them to OS 13> worked on some, failing that it's a complete reformat & reset with ADE
