Apple Fixes Bug That Bricked Some Intel Macs After macOS Monterey Install
Apple has fixed an issue that could cause some Intel Macs with a T2 chip to fail to boot up after macOS Monterey was installed, Apple said in a statement. There was a problem with the firmware on the Apple T2 security chip that prevented some users from being able start their Macs after updating to the macOS Monterey software.
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.
Following the launch of macOS Monterey, there were
multiple reports from users who found their Macs bricked after updating. Affected users were unable to turn their Macs on, an issue that affected models with a T2 security chip that powers things like
Touch ID. Macs with M-series chips were not affected as they do not have a separate T2 chip. Macs with a T2 chip were manufactured between 2017 and 2020, with a list available below.
- iMac (Retina 5K, 27-inch, 2020)
- iMac Pro
- Mac Pro (2019)
- Mac Pro (Rack, 2019)
- Mac mini (2018)
- MacBook Air (Retina, 13-inch, 2020)
- MacBook Air (Retina, 13-inch, 2019)
