Have you figured out what's needed to use a third-party signing
certificate? I'm in the same boat at the moment... I want to have
everything verified before the user installs the MDM profile.
@GeoffWiddowson sorry to reply to such an old thread! But from my
understanding, the Team ID isn't enough, you need to add the actual
kernel extension bundle ID's too, or the user won't be able to allow
them?
I too am getting this randomly... but the enrollment configuration
downloads just fine, so I am ignoring it for now... would be nice if
this didn't happen at all though
