macOS 12.3 and iPadOS 15.4 have been released and at long last Apple added Universal Control, the much-anticipated feature that was revealed at WWDC 2021. Late last year, Apple announced that the release of Universal Control would be delayed to this spring, and now it’s finally here.

During the demo in the WWDC keynote, Apple VP Craig Federighi merely placed the iPad next to his Mac, and it worked. No cables to connect, no restarting, no need to click anything or say “please.” After some brief setup, it really does work like magic.
