Apple just released macOS Big Sur 11.2.1, and also released macOS Catalina 10.15.7 and macOS Mojave 10.14.6 updates at the same time. The focus of this system update is believed to be to fix the sudo bug that was discovered last week. Simply put, this bug allows hackers to use malicious programs and other tools to gain root access to the computer.
For some users who use the 2016 or 2017 version of MacBook Pro, their computer may not be able to charge normally. After completing this system update, the problem should be resolved. In addition, the macOS Big Sur and macOS Catalina updates also fixed security issues related to the Intel Graphics Driver for two months.
Users can check and update through the “System Preferences” in the Apple menu, and then click “Software Update”.
