Apple's latest updates, iPadOS 16.4 and macOS Ventura 13.3, have reportedly broken Universal Control and Handoff features for many users. Universal Control allows users to control multiple iPads and Macs using a single mouse, keyboard, and trackpad, while Handoff technology allows users to start work on one device and switch to another nearby device. Users have reported that these features are nonfunctional after updating to the latest versions. Apple is rumored to be releasing iOS 16.4.1 and iPadOS 16.4.1 to fix the bugs.
