My Keychron Q1 keyboard pairs nicely with the Mac Studio and the the iPad Pro M4 13", fn-1 Mac, fn-2 iPad. The other part was the pointer, mouse, trackball ??? My Logitech MX Ergo Wireless trackball paired up OK with the iPad but not easily like the Keyboard. It is rather large to have 2 of them on a desktop. Finally with some knowledgeable advice I purchased the latest Apple Magic Trackpad-Black Multi-touch Surface. It instantly paired with the iPad, and it works great. The KeyChron Q1 about the same price as the Apple Magic keyboard but being totally customizable incomparably better.
