Some macOS system directors are dealing with points upgrading to macOS Big Sur 11.1, which was launched to the general public final week. As detailed by ArsTechnica, the bug in query causes the macOS 11.1 replace to vanish from System Preferences.
The issues appears to be that Macs are requesting the macOS Big Sur 11.0.1 replace relatively than 11.1:
Developer Victor Vrantchan, of the open supply MicroMDM venture, says he’s discovered the issue. Some Macs are erroneously requesting 11.0.1 as a substitute of 11.1 from Apple’s replace server—which replace is then rejected if the machine in query is already operating 11.0.1 or newer, as most such are.
Upon a restart, the macOS Big Sur 11.1 replace will reappear within the System Preferences software however then disappears once more. The report explains that the issue solely appears to have an effect on Macs related to a Mobile Device Management system. Removing the MDM profile makes the replace seen:
Removing the MDM profile—for you non-Mac of us and non-sysadmins, that’s Apple’s misleadingly named Mobile Device Management service, which permits schooling and enterprise orgs to handle and “supervise” fleets of macOS and iOS units—additionally makes the replace seen. That mentioned, mortals mustn’t do this workaround calmly; messing with MDM has doubtlessly extreme impacts on system safety, and there’s no assure that re-enrolling the Mac in its office will go easily, both.
The concern is additional compounded as a result of Apple is now not providing delta and combo macOS updates as standalone downloads, as we reported yesterday.
This concern ought to be capable to be resolved by way of a server-facet repair by Apple. A thread on the Jamf assist boards has extra particulars about the issue, plus some further points users are at present dealing with.
