Since upgrading to 9.72, we have a seen a steady trickle of Macs falling into an 'unmanaged' state. The machines still check in, and have the updated binary, but they show as unmanaged. They seem to fall into two groups:
- Showing unmanaged in JSS, when you check details the "Allow JSS to perform management tasks" box is unchecked. I can then check it and type in our management account username, the password is pre-filled.
- Showing unmanaged in JSS, and all inventory including basics like OS and Hardware are lost. If you Edit > General on these machines, the option to manage is not presented.
Enforcing management or running sudo jamf manage often yields 'Device Signature Error - A valid device signature is required to perform the action'.
Some machines re-enrolling works, others we get the Device Signature Error.
Anyone else seeing similar things after moving to 9.72?
