Apple today released macOS Big Sur 11.2.2, the fourth update to the macOS Big Sur operating system that launched 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 for free on all eligible Macs using the Software Update section of System Preferences.

According to Apple's release notes, the macOS Big Sur update prevents 2019 or later MacBook Pro models and 2020 or later MacBook Air models from being damaged when connected to certain third-party, non-compliant powered USB-C hubs and docks.

There have been several reports on Reddit from Mac users who have connected USB-C hubs and docks to their machines, resulting in the machine becoming non-functional. Affected Macs appear to go blank and unresponsive shortly after connecting the dock. Many of the users who experienced issues were using hubs and docks not purchased from reputable companies.

Many of the complaints were from M1 Mac users who had a MacBook Pro or a MacBook Air, but Apple's release notes suggest other models were affected as well.

So, is this only being made available for 2019 and 2020 MacBooks? What about older MacBooks? And are there any other bug fixes in this release?

As usual, it'll probably be several hours before this shows up in System Preferences despite refreshing. Just want to know whether I need to check for this at all, or not.

Give us ports back so we don't need hubs and dongles in the first place.

Post circa 1998: “Give us back the floppy drive and SCSI ports so that we don’t need hubs and dongles in the first place.”

USB-A and Thunderbolt 2 are ports of the past. The USB-C / Thunderbolt 4 connector can do literally everything that the old ports did, but with an industry standard connection.

Not too mention there are other uses for hubs (eg. docking stations) which wouldn’t be “solved” by adding in legacy ports.

My M1 has an issue with my USBC hub and frequently crashes and automatically restarts. The error log points to the USB hub. Hoping this will fix it. Having said that - no update available for me yet - still stuck on 11.2.1

Downloading on a 2015 Macbook. When updates don't show up for me, I just restart my machine and the updates then appear.
