Apple released macOS Monterey to the public last month with new features like focus modes, shortcuts, and more. But for older Mac users, the update has disabled their devices and prevented them from booting.
The company now says it has identified an issue affecting the T2 security chip that caused this issue. You fix it to prevent it from happening in the future. The T2 chip is present in most Macs released between 2018 and 2020.
The company did not say which systems are likely to be affected. However, she said that a very small number of users encountered the problem.
« We’ve identified and fixed a firmware issue with the Apple T2 security chip that prevented a very small number of users from booting their Mac after updating macOS, » the company said in a statement. Updated firmware is now included in current macOS updates. Any user affected by this issue can contact support for assistance.
To prevent this issue from occurring for additional users, the company has released an updated version of BridgeOS firmware that runs over the T2 security chip. Affected users are asked to contact technical support for assistance.
This means that the updated version of the released T2 chip firmware is not intended to resolve the issue for affected users. Instead, it is intended to prevent the problem from occurring to any additional users. The company says that the firmware for the T2 security chip is now included in existing macOS updates.
There is no easy way to recover if the device crashes as a result of the update:
