Apple today released macOS Big Sur 11.2.2, the fourth update to the macOS Big Sur operating system that was released in November. MacOS Big Sur 11.2.2 comes two weeks after the release of macOS Big Sur 11.2.1, a bug fix update.
The new MacOS Big Sur 11.2.2 update can be downloaded free of charge on all eligible Macs through the Software Update section of System Preferences.
According to Apple’s release notes, the macOS Big Sur update prevents MacBook Pro 2019 or later and MacBook Air 2020 or later models from being damaged when connected to certain third-party unsupported powered USB-C hubs and docks. .
There have been several reports on Reddit of Mac users who have connected USB-C hubs and docks to their machines, resulting in the machine not working. Affected Macs seem to go blank and unresponsive shortly after docking is connected. Many of the users who experienced problems were using hubs and springs that were not purchased from reputable companies.
Many of the complaints were from Mac M1 users who owned a MacBook Pro or “MacBook Air,” but Apple’s release notes suggest other models were affected as well.
