The macOS Monterey 12.3 beta prepares the operating system for new ultra-wideband (UWB) technologies on Mac.
The latest macOS 12 beta includes the frameworks and daemon needed to support ultra-wideband technology. These are the same tools already used to provide UWB support on iOS devices using the U1 chip.
Ultra-wideband technology is a short-range wireless communication protocol that works by using radio waves to manage communications between two or more devices. In its simplest form, it can be used to transmit messages between devices, which makes it somewhat analogous to Bluetooth or Wi-Fi. Apple uses it for example to improve the iOS AirDrop function which, as you know, allows you to quickly exchange files between two compatible devices. This way, two or more UWB devices in the same room can locate each other much more accurately.
Apple first introduced UWB technology in the iPhone 11 in 2019, then rolled it into the Apple Watch, HomePod mini, and AirTag as well. In the Apple ecosystem, this technology enables better AirDrop authentication, faster AirPlay connection, greater accuracy in Find my network, and stable and fast connection in wireless CarPlay.
These advantages could be extended to the Mac, probably with future models possibly equipped with a U1-like chip. In fact, macOS 12.3 already contains everything needed to manage ultra-wideband technology.
