I think the larger concern is that the world's most valuable company can't find the time to fix their window manager.

It’s not ‘broken’ just because it’s not quite designed as you’d like.

Sorry, would "functionally inferior" be a more suitable name for it? I've come to expect robust and fully-featured WMs from years of using Windows and Linux, it's a bit funny to me that Apple has just given up in this respect.

Lack of cruft and fuss is a feature though. And how's it not 'robust'?

Lack of cruft is a feature on Linux boxes, where people care about running a lean machine. My Mac is a slow, hulking trash box that runs Telegram and slurps bandwidth through a swizzle-straw. I frankly don't care about how little cruft my WM has when my system idles at 4 gigs of memory usage.

Apple needs a few things to make their WM competitive out of the box: 4/6 corner tiling would probably be a good place to start: split-screen is useless. Hopefully they would have an auto-tile functionality like Yabai, Pop Shell or i3-gaps, since I've come to expect that on my high-res devices too. They should also copy Microsoft's FancyZones, which let you quickly draft window presets to keep your screen divided the way you like it. Any of these would be welcome additions, because currently it feels like my Retina display is being put to waste with only two or three apps all fighting for attention.

They clearly don't need this stuff and they clearly are competitive already, given their market share with developers. I'd hate to see Apple cram in all these wacky features you're describing - I much prefer a simpler system.

It's not really broken, it's just not meant for power users

Broken might be a bit heavy-handed, but it's not like I'm chiding some tiny mom-and-pop store for writing bad software. This is Apple, a company that has been developing their current operating system for nearly a decade. In that time, the closest their window manager got to a glow-up was the introduction of split-screen tiling. Pretty pathetic if you ask me, which is why I have to install Yabai on every godforsaken Mac I own. I'm not following them into the ARM transition if they don't fix the basics of their OS.

You mean you find it ridiculous that you need extra software to make macOS input bad?

HID (be it my mouse or trackpad, on either my Mac mini or MacBook) input works excellent on my Mac's. Nothing wrong here.

Not working how you prefer it doesn't make something unusable or broken...

BTW your supposed Mac mini has serious hardware problems, get that thing RMA'd ASAP! And man, why did you not RMA your MacBook Pro you bought a few years ago?? It was also just as broke!
