Universal Control
Universal Control enables you to use additional devices as second screens, smoothly transferring content between them using only one device. This long-awaited feature was originally announced as part of macOS Monterey, but was postponed until the fall, with a new timeframe indicating “this spring.” Universal Control debuted in the iOS 15.4 beta and will be made available to the public alongside the Monterey OS 12.3 and iPadOS 15.4 releases.
