Anecdotal studies from the weekend point out that the macOS Monterey replace could brick some Macs throughout set up, leaving machines unresponsive. MacRumors has rounded up a consultant swath of complaints from Apple Help Neighborhood boards and Twitter, describing largely related signs: unresponsive Macs that may’t be revived utilizing typical SMC and NVRAM diagnostic catch-alls.

The report, rounded up by MacRumors, mentions numerous Intel Mac fashions, from the 2015 mannequin yr all the way in which as much as 2020, however does not point out Apple silicon fashions—it makes some sense, since they’re barely smaller than Intel Macs. Do completely different updates and might not be susceptible to the identical issues.

We have requested Apple about these anecdotal studies to see if there’s a problem the corporate is conscious of or steering for folks whose {hardware} stops responding to enter after a software program replace. We even have our personal suggestions, in addition to some hypotheses as to why these main updates generally trigger a larger-than-usual variety of {hardware} issues.

macOS Updates Aren’t Simply Updating macOS

When Apple releases new macOS updates, you are not proper now Receiving updates to the working system. Since 2015 or so, Apple has distributed most firmware updates as a part of the working system, fairly than individually (this additionally contains updates for the “BridgeOS” software program working on Apple T1 and T2 Macs). For PC homeowners, think about if putting in a brand new Home windows model or Patch Tuesday safety replace additionally up to date your BIOS or graphics firmware, and there was no strategy to get to it with out getting one other.

This protects the steps for finish customers, who get the advantages of firmware-level safety and have patches just by maintaining their software program updated. Apple’s firmware patches comprise mitigations for hardware-level vulnerabilities like Specter, Meltdown, and their ilk, and Apple additionally launched up to date firmware with macOS Excessive Sierra so as to add APFS boot help to older Macs.

However bundling in firmware updates additionally provides complexity. In case your Mac is unplugged or drained of battery throughout a firmware replace, it might be unable in addition up and be unable to be revived via particular strategies. And since they’re extra intensive and take longer than a typical software program replace, each firmware updates And Main OS updates can generally detect underlying {hardware} issues with RAM, storage, or different parts.

Easy methods to Repair (and Attempt to Keep away from) These Issues

Apple T2 and Apple silicon-based Macs can be put into DFU mode and have their firmware restored by another Mac running Apple Configurator 2.

Apple T2 and Apple silicon-based Macs could be put into DFU mode and have their firmware restored by one other Mac working Apple Configurator 2.


When you’re utilizing an older Intel Mac with out an Apple T2 chip (most Macs shipped earlier than 2018), and resetting your SMC and your pc’s NVRAM does not do something, your subsequent greatest wager Contact Apple, both over the cellphone, by way of chat, or in an Apple Retailer. If the true underlying drawback is your {hardware}, they are able to repair it (although it might value you if it is out of guarantee). In any other case, they’re going to have extra instruments to diagnose and revive your machine.

When you’re utilizing an Apple T2 and have a second Mac accessible, you could have another choice. These Macs could be booted into “DFU” restoration mode, very like iOS gadgets and Apple Silicon Macs. Utilizing Apple’s directions, you’ll be able to join your “brick” Mac to a different Mac with a USB or Thunderbolt cable and use the Apple Configurator app to revive its firmware. If the Mac’s firmware is bootable after being restored, you must have the ability to use Web Restoration or a USB set up drive to get a clear set up of macOS up and working on the system. Apple silicon Macs could be recovered in an identical manner.

When you use the “Revive” possibility within the Configurator app, it is going to try to revive the firmware with out touching the info on the drive. If that does not work, you’ll be able to strive an entire wipe and restore, at the price of all of the stuff in your Mac’s inside drive. When you preserve good backups, it is well worth the bother to get your pc working once more. When you have critically essential knowledge saved in your Mac and elsewhere, or if DFU restore does not work, contacting Apple ought to be the next step.

One of the simplest ways to keep away from issues is to not replace your Mac till Apple has launched some main bugfix updates for Monterey, which is normally the good factor to do with any new software program launch. , whether or not there are intensive studies of issues or not. Apple’s safety updates for Catalina and Huge Sur usually embrace the identical firmware updates which can be included in new working programs—that is essential to patch firmware-level safety vulnerabilities—so if the issue is certainly Is On account of new firmware replace or uncovered, avoiding Monterey could not assist. However assuming that some mixture of latest firmware updates is inflicting the issues, underlying {hardware} points with particular person Macs are elusive, And A brand new main OS replace, staying on Huge Sur or Catalina for a couple of extra months can take away no less than one variable from that equation.
