I thought I was done with the “macOS user interface isn’t touch-friendly” debate but tonight, I’m reading this piece from Jack Wellborn (emphasis is mine):

The Mac was also built for a mouse, and while I would argue macOS is more usable than Windows, there is no getting around the fact that controls optimized for pointers are inherently unfriendly to touch input. It’s foolishly optimistic to think that Microsoft or even Apple can make pointer interfaces as touch friendly as iPadOS without also destroying the very thing that makes them more productive than iPadOS — information density. Smaller controls means these platforms can disclose more information and interactivity to their users at once. That’s why a bunch of windows on even a 11″ MacBook Air feels natural while only four windows on a “large” 13″ iPad feels ungainly.

Conversely, it’s impossible to make iPadOS more information dense without sacrificing the very thing that makes it the best tablet OS — touch friendliness. iPad users want more information on screen because that will help them be more productive, but the only way to present more information in iPadOS without sacrificing touch friendliness is a larger display. Not only is a larger display not portable, iPadOS’s support for larger displays still sucks. There’s nothing Apple can do about large displays not being portable, but better support for larger displays? That’s a problem Apple can solve.

I don’t agree with the author’s suggestions at the end, but it shows that the debate about macOS being touch-friendly or not is still raging and far from being settled.
