Apple Releases macOS Big Sur 11.2.2 with Safeguards Against Non-Compliant Docks

Member of the AppleVis Editorial Team

Apple has today released macOS Big Sur 11.2.2, introducing safeguards to prevent MacBooks from being damaged by non-compliant USB-C hubs and docks.

As macOS Big Sur 11.2.2 appears to have been released to address a specific issue, our expectation is that it does not contain any accessibility changes for blind and low vision users; however, if you notice any changes, improvements or regressions in your own use of this release, please post a comment with your findings.

macOS Big Sur 11.2.2 release notes

macOS Big Sur 11.2.2 prevents MacBook Pro (2019 or later) and MacBook Air (2020 or later) models from incurring damage when they are connected to certain third-party, non-compliant powered USB-C hubs and docks.

How to update

To install macOS Big Sur 11.2.2, choose System Preferences from the Apple menu, then click the Software Update preference pane to check for updates. If any updates are available, click the Update Now button to install them. Or click ”More info” to see details about each update and select specific updates to install.

More information on how to update the software on your Mac is available on this Apple Support page.
