Apple has finally rolled out “Universal Control”, a feature first unveiled in the summer. The tool allows Macs and iPads to communicate with each other so they can all be controlled by the same mice and keyboards. It was first announced at Apple’s Worldwide Developer Conference in June, when Apple said it would arrive in Autumn, but then it did not turn up. A Mac’s mouse can be used to scroll on a nearby iPad, for instance. What is your experience with the new universal control feature ?
