Some Older Macs Reportedly Bricked After Installing macOS Monterey

Here’s a different story.

I was unable to install Monterey on my 2015 MacBook Pro. After clicking on the “Restart now” button, it gave me an error that it “Could not complete the installation. Try again.” When I opened “Disk Utility” to do a disk repair, only one partition showed up. Attempting to do a NVRAM reset would go into “Recovery Mode” instead of booting up normally and show that it was attempting to do a firmware update, and it showed an error, “The installed hard drive is incompatible." Same thing while in Safe Mode. Doing a SRAM reset did not help any. Despite this problem, I was able to boot up normally into Big Sur.
So Apple authorized taking it to Argosy West for repairs. The only way they could fix the problem and save my data was to uninstall the SSD, install a blank SSD, go into Recovery Mode, finish the firmware update, put my SSD back in, and then Monterey installed normally.
I suspect that the machines that are bricked after attempting to install Monterey is a firmware issue and not a software issue. Possibly installing a blank drive would get past that problem like it did for my MacBook Pro.
I had no problems installing Monterey on my 2020 M1 Mac Mini.
So now I’m selling my MacBook Pro even though it is working normally. I no longer need a laptop.
