black screen

Last week some users of Macs from 2018 and 2019 were to the unpleasant surprise that their computers were they blocked after upgrading to the new macOS Monterey. They were left with the black screen, unable to boot. Quite a bummer.

How could it be otherwise, quickly Apple has detected the problem and has put a solution to it. The fault was in the security chip T2 of some specific models. The firmware of this chip has already been updated, and Apple is in charge of "reviving" the affected computers.

In the past week we comment that had been spotted by some users of two- or three-year-old Mac models, a major bug. Their Macs had been frozen after upgrading to the new one macOS Monterey. Quite a nuisance for those affected, since there was no way to recover the old software, and the new one blocked the computer.

The T2 security chip

Apple quickly located the problem, and has already fixed it. The "bug" resided in the security chip T2, which prevented some 2018 and 2019 Macs might boot after upgrading to macOS Monterey. the company has updated the firmware of said chip, thus solving the problem.

Said new firmware now is included with existing macOS updates. Any user affected by this problem can contact Apple Support for help on how to "revive" their Mac.

    I have a 27 ″ 5k IMac from 2017 and exactly what you say in this article has happened to it.
    I think my IMac does not have the T2. Do you know something about this?
    Before seeing your news I had to take it to a site so that they put a new hard drive and if the IMac has started. Paying a buck.
    Can I claim this from Apple?
    Yesterday I called technical service and for now this Apple has not made it official.
