Apple today released macOS Big Sur 11.2.2, the fourth update to the operating system it launched in November. MacOS Big Sur 11.2.2 was released two weeks after macOS Big Sur 11.2.1 was released as a bug fix update.
According to Apple’s release notes, The macOS Big Sur 11.2.2 update prevents 2019 or later MacBook Pro models and 2020 or later MacBook AIr models from being damaged when connected to certain third party, nonconforming USB-C hubs and docks.
I learned that there have been several reports on Reddit from Mac users who claim that connecting usB-C hubs and docks to their devices makes them unusable. Affected Macs seem to go blank and unresponsive shortly after connecting to the base. Many of the users who encountered problems were using hubs and docking stations that were not purchased from reputable companies.
Many of the complaints came from M1 Mac users who own a MacBook Pro or MacBook AIr, but Apple’s release notes show that other models are also affected.
