Apple has released macOS Big Sur update 11.2.2 with a fix that prevents certain non-compliant USB-C hubs and docks from damaging some models of the MacBook Pro and MacBook Air.

The update is available to users manually by opening System Preferences then selecting Software Update. It will also be installed automatically on systems for users who enabled that setting.

This update is especially useful for people who bought USB-C cables from 3rd party vendors that offer cables with sub par quality and also to those who have damaged cables due to prolonged usage. We always recommend buying from reputable brands as investing in cheap cables can damage your expensive laptops or phones.

Not all Macs will see the update. The release notes say that the update will prevent non-standards compliant powered USB-C hubs and docks from damaging MacBook Pro models 2019 or later and MacBook Air models 2020 and later. We don’t know what specific technology Apple employs to detect these cables and what the parameters they place to know if the cables are indeed damaging your computer. We are hoping to see similar technology to be applied to future charging cables for our iPhones and iPads.

This update follows the macOS 11.2.1 update that fixed an issue with MacBook Pro charging and closed a Sudo vulnerability.

We recommend installing this update to prevent your computer’s internal chip board and battery from being damaged.
