Because using macOS on a ****ing touch device is ****ing stupid. Have you seen microsoft surface? Tremendous hardware. They are masterpieces. Yet, people use them as excellent laptop and not use them as tablets. Why? Because the buttons, ui are so small it is damn small. Now, use macOS with your finger that has even smaller buttons and UI then Windows. I dare you, your expectation will be shattered.Apple already said there will be no macOS on iPad, but people still hope. But you have privacy and no awful flea market, trust Tim and buy these pro devices!
In short, why change the UI that is tailored for touch and cram macOS that is tailored for mouse pointer?
What we needmis adding more functionality to ipadOS and maybe ability to run mac apps by catalyst or something. Not macOS in iPad
