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.
