Apple first introduced its ultrawide band chip (UWB) to the iPhone 11 series, and shortly after, the same feature made its way to the Apple Watch, HomePod mini, and AirTags. Now there is a chance that the same feature could slither into the Mac, according to macOS 12.3 Monterey beta.

Apple’s macOS 12.3 Monterey brings features like Universal Control and secure notes in Safari’s password manager. However, one addition that was not talked about was how the update could get UWB support for the Mac, as suggested by 9to5Mac, who reports this inclusion via internal system files. Currently, UWB support is unavailable for the Mac or iPad lineup, explaining that Apple could be testing the feature on these two product ranges.
