TheyРІР‚в„ўll just do a logic board replacement again which will fail on upgrade. ThereРІР‚в„ўs seemingly no point going to the Apple Store Genius Bar based on sfriedrichРІР‚Вs comments. In the meantime, thereРІР‚в„ўs going to be many bricked MBPs as most people wonРІР‚в„ўt have a second Mac to preform a revive, and even if they do, wonРІР‚в„ўt understand why that fails as it tries to load 12.3. IРІР‚в„ўve submitted as many logs of all this to AppleSeed via Feedback Assistant, but I suspect this will take days to actually get to someone to can acknowledge the issue. The Mac will then restore 12.2.1РІР‚в„ўs OS, keeping your data upon finishing.

This will update the firmware of iBoot, and the recovery image to a working build. The only way to get things running again is to manually download the 12.2.1 IPSW and use Apple Configurator 2, with the Mac in DFU mode, to load the revive image.This will fail, because it tries to load the 12.3 firmware from the IPSW, in either DFU or Recovery mode. You can try and revive using a second Mac with Apple Configurator 2.YouРІР‚в„ўll see the apple icon flash on boot 5-6 times before seeing the exclamation mark symbol telling you recovery is needed. You try to upgrade, the upgrade will fail but recovery to handle it correctly, youРІР‚в„ўll reboot still on 12.2.1 but with a report a problem dialogue informing you of an iBoot Panic.

There is a firmware bug in Mac OS 12.3 that renders the update impossible to install on any 2021 14 or 16 inch MacBook Pro that has had itРІР‚в„ўs logic board replaced. Others quickly chimed in, reporting the same experience. I restored using Apple Configurator and DFU mode and have tried every possible permutation of updating to the Monterey beta only to receive the same result. This resulted in a boot loop and effectively bricked the computer. So I tried to update to the Monterey beta from within system preferences.

When I was restoring my time machine backup, migration assistant advised updating to the Monterey beta since thatРІР‚в„ўs what OS my backup used.Р”Р„ccepting this prompt within migration assistant restarted the machine but did not complete the update. They replaced nearly everything- from the logic board to the batteries to both cases and fans. In February, I spilled aР’В fullР’В cup of coffee next to it and brought it in for Apple Care repair. Installed the Monterey beta on it at the end of January. I bought a 16-inch M1 Pro MacBook Pro in January. MacRumors spotted the reports on the Apple Developer Forums. Making things worse, the only assistance Apple Stores are offering is to again replace the logic board, which fails to resolve the problem. Specifically, the issue appears to affect M1 MacBook Pro models which have had their logic board replaced РІР‚В¦

There are reports of repaired M1 Macs being bricked when attempting the upgrade. Apple released macOS 12.3 on Monday, but not everyone is succeeding in upgrading.
