That is an update for Magic Keyboard, Magic trackpad, and even Apple's large-capacity charger.
In an era where users are so used to having their computers, smartphones or tablets continuously receive software updates, many people may not have expected that even a seemingly smooth accessory like a charger can be updated. But that is exactly what Apple has done today, along with a new update to some other popular Mac accessories.
It is not yet clear what these updates change or add. Most likely they are aimed at increasing compatibleity with some new devices, or fixing some rare errors in special cases.
However, users may not notice any new points when typing on Magic Keyboard or Plug-in charging with a 140W charger.
The update for these accessories is automatically installed in the background, so just continue using it as usual, the device will be updated soon without manual operations.
