Apple really needs to spend a whole release cycle just fixing existing bugs instead of making new features.
Even simple things are faltering, like when logging in, macOS stops registering keypresses in the middle of entering my password. Switching screens around when docking my MacBook Pro. Important features like Time Machine silently corrupting your files.
It's such a shame that macOS just keeps getting more buggy. I've read from multiple (ex) employees that there's no real incentive to fix bugs, since employees seem only to be rewarded when they're working on prestige projects.
What good is investing so much R&D into new hardware like Mac Pro when the operating system is the limiting factor?
