Apple introduced macOS Big Sur 11.2.1 to the public on Tuesday, taking care of a bug that prevented some MacBook Pro models from charging.
The update also removes security problems. Plus, Apple also released updates for macOS Catalina and Mojave to remove the same security bugs.
What’s new in macOS Big Sur 11.2.1
Given the tiny jump from version 11.2, it’s not surprising there are no new features. And Apple’s official release notes for the latest version mention only one bug, stating “macOS Big Sur 11.2.1 addresses an issue that may prevent the battery from charging in some 2018 and 2017 MacBook Pro models.“
But there are also multiple security fixes. There are two in the Intel Graphics Driver and one in Sudo. Visit Apple’s support website for more details.
Apple doesn’t overlook those who are unable or unwilling to upgrade to Big Sur. On Tuesday, the company also released macOS Catalina 10.15.7 Supplemental Update and macOS Mojave 10.14.6 Security Update 2021-002 with the aforementioned security holes closed.

Anyone running macOS Mojave or later can get the latest version of macOS Big Sur via Software Update: Go to the Apple menu > System Preferences, then click Software Update. Another option is to install the new version from the App Store.
This release comes just a week after the launch of macOS Big Sur 11.2, which took care of a Bluetooth bug.
