Apple releases macOS 11.2 update
A week following the 14.4 updates for Apple's mobile system software, Today Apple released the second major update for macOS Big Sur. Like most of Apple's updates, this addresses many bugs, security, and performance problems that are and aren't mentioned in the update notes. In particular, this update addresses issues with Bluetooth, external monitors, and problems some people have had with the new M1 Macs. My personal experience is that my computer is running much faster compared to 11.1.
To update
Click the Apple menu > System Preferences > Software Update (wait for a few seconds or press Command-R if it doesn't show).
