Today, Apple released a small update to macOS Big Sur, numbered 11.2.1. Primarily, it fixes a problem affecting some MacBook Pro models that prevented their batteries from charging properly.

The update also fixed a sudo bug that could in some cases play a part in allowing an attacker to gain root access to the device, plus some other security-related updates.

Apple also released supplemental updates for Catalina 10.15.7 and Mojave 10.14.6 to address the same security issues.

Apple's very short release notes for this update are as follows:

macOS Big Sur 11.2.1 addresses an issue that may prevent the battery from charging in some 2016 and 2017 MacBook Pro models.

Some features may not be available for all regions, or on all Apple devices.
