Numerous macOS system directors began earlier this week reporting that some Apple gadgets couldn’t improve to Massive Sur model 11.1. Affected customers might briefly see the 11.1 improve, nevertheless it disappears from the replace UI and from the command line
softwareupdate Instrument despite the fact that it was not put in.
Incorrect replace request
Developer Victor Vrantchan from the open supply MicroMDM challenge says he discovered the issue. Some Macs incorrectly request 11.0.1 as an alternative of 11.1 from the Apple replace server. This replace will then be rejected if the pc in query is already working 11.0.1 or later, like most others.
Whereas the faulty requests themselves are clear sufficient, the damaged state is much less. In accordance with Vrantchan, the faulty request “one way or the other compromises the standing of the software program replace,” which implies that the system now not reveals the replace as an possibility within the system settings.
The replace turns into seen once more by restarting the affected system. Nevertheless, this may increasingly or might not assist. If the subsequent try to put in 11.1 generates the identical dangerous 11.0.1 request, the issue conduct simply repeats itself.
By eradicating the MDM profile – for non-Mac customers and non-system directors – that is Apple’s misleadingly named Cell System Administration service that instructional and enterprise organizations use to handle and “monitor fleets of MacOS and iOS gadgets.” ” can. That’s, mortals should not do that workaround calmly; The mess with MDM may have critical system safety implications, and there’s no assure of it Re-The registration of the Mac at its workstation additionally runs easily.
Can I simply manually obtain the 11.1 replace?
A seemingly apparent workaround is to obtain the Massive Sur 11.1 replace bundle straight and apply it manually. Sadly, Apple has rejected combo replace packages there is No guide bundle to obtain or set up.
As of macOS Massive Sur, the format of the updates has modified – and so they can now not be put in with out web entry. Replace packages should come straight from Apple and be managed by Apple
softwareupdate Course of itself. It isn’t even doable to make use of a customized url for
softwareupdate no extra.
How – or when – can I repair this?
Till we now have extra particular details about the causal situation
softwareupdate Should you mistakenly request 11.0.1 as an alternative of 11.1, there isn’t a assured strategy to repair the issue. Many customers report that after a reboot and retry improve, in some circumstances, reboot and a number of makes an attempt, the improve completes accurately.
Different customers report that eradicating the MDM profile fully fastened the issue – though we’d nonetheless take into account this to be a really dangerous recreation by Hail Mary.
As a result of system updates can’t be manually downloaded and put in as user-installed packages in Massive Sur, it may be tough to troubleshoot. The error might not happen if the system requests a special model quantity. Subsequently, an replace to 11.2 might bypass the faulty necessities and may due to this fact repair the error within the 11.2 with out intervention. It could even be doable for Apple – albeit extraordinarily hacked – to load the replace into an unrelated patch that does not have an effect on the model variety of the working system.
If all else fails, a full reinstall of Massive Sur from the App Retailer ought to get you to 11.1 – despite the fact that it is a 12.6GB obtain, and like all main OS set up, you have to be completely positive you could have good ones Have backups of all of your information earlier than making an attempt.
