macOS Big Sur 11.2.2 prevents damage from non-compliant USB-C accessories
The update addresses an issue that could cause a 2019 or later MacBook Pro, or a current MacBook Air, to be damaged by non-standard USB-C accessories.
Apple writes about this:
macOS Big Sur 11.2.2 prevents the MacBook Pro (2019 or later) and MacBook Air (2020 or later) from becoming damaged when connected to certain non-compliant third-party USB-C hubs and docks.
Various reported users for example, that their MacBooks became unusable shortly after they were connected to a USB-C dock. MacBooks with an M1 CPU appear to be particularly affected, but Intel Macs also receive today’s update. Have you ever been affected by this disorder?
It is unknown whether the update also fixes problems where MacBooks no longer load reliably.
