Apple seeds macOS Big Sur 11.2.2 to prevent MacBook Air and Pro from getting damaged by third-party docks

Apple has released the macOS Big Sur 11.2.2 update, just two weeks after the launch of macOS Big Sur 11.2.1. The new update brings damage protection for MacBook Air and Pro models from third-party docks and USB-C hubs.

The previous macOS Big Sur 11.2.1 update included bug fixes as well like it fixed a security bug with sudo, a vulnerability that could give root access to hackers.

Sudo is used in macOS, Unix, and Linux operating systems, and allows users to run apps with superuser privileges. With the vulnerability, attackers with access to the system could gain root access through the use of malware or accounts with non-admin access.

In addition, it also fixed a battery charging bug that did not allow some 2016 and 2017 MacBook Pro models to charge. Prior to that macOS Big Sur 11.2 update was released with bug fixes for Bluetooth reliability, external display connectivity with M1 Macs, iCloud Drive, System Preferences, keyboard globe key, and more.

macOS Big Sur 11.2.2 update for 2019 MacBook Pro and 2020 MacBook Air models

Release note reads;

• macOS Big Sur 11.2.2 prevents MacBook Pro (2019 or later) and MacBook Air (2020 or later) models from incurring damage when they are connected to certain third-party, non-compliant powered USB-C hubs and docks.

However, the company has not issued a statement on the fate of the MacBook models which have already been damaged due to third-party docks and USB-C cables. The next software upgrade macOS Big Sur 11.3 Beta 2 is already seeded to developers for testing.
