macOS Monterey seems to have a high chance of something going wrong compared to previous OS versions,Disaster that will brick old Macs was reported last NovemberI didn’t expect a similar case to appear in the new version of macOS Monterey 12.3 following more than 3 months, but most of the people encountered this time have replaced the motherboard (and they are all MacBooks) before, but there are also sporadic cases that are not special. It is mentioned whether it has been changed, so those who have not upgraded remember to wait first, and it is better to upgrade following the problem is determined, especially for Mac workers.
macOS Monterey 12.3 has not been upgraded, please suspend, some users report that the Mac becomes bricked following the upgrade
macOS Monterey 12.3 has added a new Universal Control universal control function, I believe many people want to try it, but those with bad luck may not even touch it, and the Mac will become bricked. According to MacRumors reports, recently on the foreign Apple developer forums and Reddit, many users reported that this happened when they upgraded macOS Monterey 12.3.
The first response to this question wasone jjg08d user who said he bought a 16-inch M1 Pro MacBook Pro in January, installed the macOS Monterey beta at the end of January, and accidentally spilled a whole cup of coffee next to it in February and brought it back to Apple repair. Apple replaced almost everything, including the motherboard, battery, case, and fan. After fixing it, he used the backup and restore function. The restore assistant suggested updating to the beta version of macOS Monterey, which was the version of the operating system he backed up earlier, but he pressed accept. After the update failed, he tried to update directly from the system settings, but the result was bricked and restarted infinitely:
one stredrich Reply: “Unknown reason, this happened to my MacBook too, it got bricked following upgrading to macOS Monterey 12.3 beta 3, and trying DFU recovery mode didn’t help either. After I sent it to Apple Support, they replaced the console. After Monterey 12.3 beta 4 came out, I thought the problem was solved, but I didn’t expect it to become bricked once more following the upgrade, and the motherboard also needed to be replaced, so please be careful, there has never been a software that caused the need to replace the motherboard in the past, hope it wasn’t before the disaster omen.”:
Reddit Some people on the forum also responded to the situation of bricking. The FluffIncorporated even mentioned that he mightn’t even enter the DFU recovery mode:
MacRumors ForumAlso, one user said: “My MBP 2021 also had a motherboard replacement before. Can’t install macOS Monterey 12.3 by any means, be it a direct upgrade, install from the App Store, recovery mode, or DFU, all failed. So in the end I Had to download and use macOS 12.2 IPSW. I think there must be something wrong with the new MBP board replacement, I have been unable to use Apple Pay for months.”
Apple has yet to respond to this matter, but someone mentioned that macOS 12.3 has a firmware bug that affects 2021 14-inch or 16-inch MacBook Pros that have had their motherboard replaced:
