The company says it has identified and addressed a case with firmware on a T2 security chip that prevented a “small number of users” from booting their Macs after an update to macOS Monterey.
Apple has solved an issue that could brick some Intel-based Mac models equipped with T2 chips on the installation of macOS Monterey.
In a statement, Apple said that the firmware update is now included with the available macOS updates.
Apple also advises users who have been affected by the problem to contact Apple Support.
Earlier this week, rumors began circulating that macOS Monterey was causing some Intel-based Macs to become responsive after the update.
The issue appears to be related to Intel’s T2 security breach on Macs, which drives features such as Touch ID.
Mac models equipped with Apple’s M1 are not affected by a particular case, because they do not have T2 chips, the report said.
Any firmware update is somewhat risky, though, and the issue can be resolved using the Apple Configurator application, if it comes out, it adds.
In addition to the boot problem, a small number of users have also complained about memory leaks after the update to macOS Monterey.
