Apple has confirmed a fix for bricked Intel-based Macs after the devices were updated to macOS Monterey. Previously, some owners of Intel-based MacBook Pro and iMac models complained that they could not turn on their Macs after installing macOS Monterey. It was accurately estimated that the issue was related to BridgeOS which is a part of T2 chips.
Apple released macOS Monterey to the public in October with redesigned Safari and new features like Live Text, Focus mode, iCloud+, AirPlay support, improvements to built-in apps such as Messages, Notes, Apple Maps, and more.
Apple patches issue with T2 security chip on Intel-based Macs to run macOS Monterey
@Rene Ritchie shared Apple’s statement on his Twitter account, it reads:
We have identified and fixed an issue with the firmware on the Apple T2 security chip that prevented a very small number of users from booting up their Mac after updating macOS. The updated firmware is now included with the existing macOS updates. Any users impacted by this issue can contact Apple Support for assistance.
In addition to this boot fix, Apple has to patch other issues as well. Several owners of M1 and Intel-based Macs are facing USB-hub connectivity issues. The built-in USB hubs and the USB devices are not working properly with updated Macs. Previously, users reported memory leak issues with the latest macOS Monterey update which makes apps use excessive memory without any limitation. Some macOS features like Control Center took up to 20 GB of RAM, which usually consumes 50MB.
