macOS software update reports managed by administrator unexpectedly

Scenario

A standalone Mac suddenly claims updates are managed by an administrator even though no one expected central management.

Check for leftover MDM enrollment, ADE history, or configuration profiles from prior ownership.
Review installed profiles and remove only those you can account for.
Confirm whether the Mac was ever part of a business tenant before making support promises.
Document chain of custody if the device was inherited or repurposed.

Document what changed, what confirmed the fix, and whether the issue points to a broader standards gap worth addressing for the client.
