Since macOS Monterey was launched, there have been a number of Apple customers who mentioned that putting in the replace bricked their computer systems. It was unclear what might need prompted the problem till in the present day, as Rene Ritchie reports, he has obtained this assertion from Apple citing a problem with the firmware of its T2 safety chip (by way of 9to5Mac).
We’ve recognized and stuck a problem with the firmware on the Apple T2 safety chip that prevented a really small variety of customers from booting up their Mac after updating macOS. The up to date firmware is now included with the present macOS updates. Any customers impacted by this concern can contact Apple Assist for help.
There aren’t any specifics on the fashions affected, potential settings or configurations which can be weak, or precisely what a “small variety of customers” provides as much as. MacRumors was capable of finding tweets from no less than 9 MacBook, MacBook Professional, and iMac house owners who mentioned their units didn’t boot up after the replace. It’s good that they’ll attain out to Apple Assist for help, but it surely’s additionally unclear if these individuals will be capable of retain any information locked in affected units.
The T2 safety chip has appeared in quite a lot of Apple computer systems (you may test the checklist right here) because it was launched in 2018. Apple says that up to date firmware to remove the problem is now included in present macOS updates (some trackers noted a refreshed version of the BridgeOS 6.0 software that runs on the T2 going out in the present day), so it shouldn’t be a problem on any of these machines to any extent further.
