macOS 12.3 hints at ultra-wideband technology for Macs

Apple released the first beta of macOS Monterey 12.3 this week, with new features like universal controls and secure notes in the Safari password manager. The update also prepares new technology for Apple's desktop operating system, as internal system documents hint that ultra-wideband (or UWB) is coming to Macs.

The latest beta version of macOS 12 includes the frameworks and daemons (they are part of the system that runs in the background) required to support Ultra Wideband technology. These tools are already used to provide UWB support on iOS devices with U1 chips.

For those unfamiliar, ultra-wideband technology is a short-range wireless communication protocol used for spatial awareness. In this way, two or more UWB devices in the same room can be precisely positioned with respect to each other.

Apple first introduced UWB technology to its devices with iPhone 11 in 2019, then expanded it to Apple Watch, HomePod mini, and AirTags. Within Apple's ecosystem, it enables faster AirDrop, CarKey authentication without even taking your iPhone out of your pocket, fast AirPlay transfers, and precise location using the Find My network.

These advantages may extend to Macs if Apple decides to introduce the U1 chip into its computers. However, it's worth noting that even the latest iPad models don't feature UWB technology, so the only thing we know for sure now is that Apple is already experimenting with UWB technology on more devices. It's unclear when we'll see Macs and iPads with U1 chips.
