The newest version for macOS Monterey is now out, with a plethora of new features. While there’s a lot to be enthused about, MacBook Pro users may want to wait a while before upgrading. It appears that macOS 12.3 is bricking certain Macs, according to reports. The 16-inch MacBook Pro will be available in late October 2021. Christian de Looper for BGR provided the image.
Initial reports of the issue appeared on the Developer Forums as far back as two weeks ago. At the time, the beta for macOS 12.3 was readily available, and a user reported issues installing it after having multiple parts in their MacBook Pro replaced. A week later, another user responded to the thread, sharing that it had happened to them as well.
The release of macOS 12.3 was exciting news for Mac users. The new version finally gave us Universal Control, Apple’s answer to using multiple devices at the same time. While the new features are exciting and worth downloading the update for, some Mac users may put their computers at risk by updating to the latest version. Unfortunately, it appears that macOS 12.3 is responsible for bricking several Macs that have had their logic boards replaced. Multiple reports have appeared on the Apple Developer forums, as well as on social media websites like Reddit. Fortunately, the problem does not appear to affect all Macs. Instead, it appears to be tied directly to new 14-inch and 16-inch MacBook Pros that have had their logic boards replaced.
Other responses were added to the thread. Later, an additional user noted down the cycle that many with replaced logic boards may run into.

According to the thread on the Apple Developer Forums, there are two possible outcomes when users try to upgrade to macOS 12.3 on a MacBook Pro with a replaced logic board. The upgrade can fail, which will kick the computer into recovery. You’ll reboot on 12.2.1, with a problem dialogue from iBoot Panic.
This isn’t the first time that we’ve seen issues with macOS Monterey bricking Macs. When the operating system was first released, many reported that macOS Monterey bricked older Macs. Unfortunately, Apple has yet to comment on the issue in any capacity. Users are hopeful the company will release a fix for the issue soon, allowing them to update to macOS 12.3 now that it is readily available.
If you try to upgrade again, however, you’ll corrupt the iBoot FW drive. When that happens, you’ll have to revive it using a second Mac with Apple Configurator 2 to install macOS 12.2.1. It’s also possible that trying to update to macOS 12.3 will immediately corrupt the system. If that happens, you’ll need to use a second Mac with Apple Configurator to install the previous update again.
