Activation Lock codes can become a wipe-time risk on managed Macs

A supervised Mac managed through Apple Business Manager can have a device-based bypass code for unlocking Activation Lock. After repeated lock and unlock cycles, re-enrollment, re-supervision, or key rotation, Apple may create a new bypass code and make the old one unusable.

The operational problem is that many MDM records show only the latest stored code, without a timestamp or a history of older codes. If the code was stored late, or an admin copies an older value, the Mac may be wiped and then fail to unlock because the entered code is no longer valid.

There may also be no clear way to see which code Apple currently accepts. The practical question is whether teams should keep their own timestamped history of stored codes before re-supervising, or whether the newest code shown in MDM is reliable enough.
