Apple has announced that it has fixed an issue that could cause some Intel Macs with a T2 chip to fail to boot up after macOS Monterey was installed. This was coming after some users have a complaint to be encountering problems with the firmware on the Apple T2 security chip that prevented them from being able to start their Macs after updating to the macOS Monterey software.
In the announcement, Apple says that a BridgeOS firmware update is now included with the existing macOS updates to prevent further failures, and users already impacted by the issue should contact Apple Support for assistance with their machines.
Apple has fixed the bug that could cause macOS Monterey to cause a brick on Macs with a T2 security chip and if your computer failed to boot after updating, contact Apple Support.
It should be recalled that since the macOS Monterey was released, there have been several Apple users who said that installing the update bricked their computers. It was unclear what might have caused the issue. Apple made this announcement that it is an issue with the firmware of its T2 security chip.
There aren’t any specifics on the models affected, possible settings or configurations that are vulnerable, or exactly what a “small number of users” adds up to. However, reports show that quite some of M k, MacBook Pro, and iMac owners said that their devices didn’t boot up after the update. They tried to reach Apple Support for assistance but it is unclear if those people will be able to retain any data locked in affected devices.
The T2 security chip has appeared in several Apple computers since it was introduced in 2018. Apple says that updated firmware to eliminate the issue is now included in existing macOS updates (some trackers noted a refreshed version of the bridges 6.0 software that runs on the T2 going out today), so it shouldn’t be an issue on any of those machines from now on.
