Apple Fixes macOS Monterey Bug That Left Macs With T2 Chip Bricked
Apple, in a statement has said that a critical bug within macOS Monterey which rendered MacBooks, iMacs and Mac Pros with the T2 chip to not boot or soft-bricked, has now been fixed.
Since its release, many users of Apple’s Touch ID-powered Macs were popping up complaining that their machines were effectively bricked.
The issue it appears, is exclusive to all Macs featuring the T2 chip, which powers things like the Touch ID.
In a statement issued to Rene Ritchie, Apple said that the issue was found in the T2 security chip’s bridgeOS firmware, but it has since been fixed. The bridgeOS firmware update is now part of every macOS Monterey update.
That said, this does not help users that have already been effected by this bug. Those users will have to contact Apple Support to fix their machines.
If you haven’t already updated to macOS Monterey yet, please do make sure that your Mac does not feature a T2 chip. You can refer to the list below to see if your Mac packs the T2 security chip.
