Apple recently rolled out public beta versions of its various operating system updates, including macOS. macOS Monterey version 12.3 brings Universal Control — one of the most awaited features — but it also reportedly gets ultra wideband or UWB to MacBooks.
According to a report by 9to5Mac, macOS Monterey 12.3 beta version has frameworks and daemons that are required to support UWB tech. The report says that these are the exact same tools that are used for UWB support on iOS devices.

What is UWB technology and its advantages?

Ultra wideband is a wireless protocol that uses radio waves for communications. For the uninitiated, Apple had first introduced UWB with the iPhone 11 two years ago. Apple put the U1 chip in the iPhone to make UWB work. The tech has made its way to Apple Watch, AirTags and HomePod mini.
UWB is used for precisely tracking location of devices that have support UWB. It also helps in faster AirDrop, AirPlay transfers and in countries where it supports, users can get CarKey authentication without taking the iPhone out of their pockets. Also, it helps in tracking the precise location of devices using the Find My network.
It will be interesting to see how Apple incorporates UWB in Mac computers. The new iPad models also don’t feature ultra wideband technology. So we can’t say whether the next MacBooks will have the U1 chip or what other plans Apple may have for UWB for its computers. Also, keep in mind that it is a feature that is found in the beta version and may not be rolled out for the public version at all. It gives an indicator that the Macs too could get the UWB in some form or the other in future.
