If you're using a USB hub/dock (the author says he isn't), you should upgrade to macOS 11.2.2 because:
> 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.
> For commercial kegs, these sales are usually announced word of mouth, and I am not well connected enough to be in the loop
I’d have thought if you had to be “in the loop” to know if something’s for sale, it means there’s a possible market for that knowledge, which a website can step in to provide.
