Apple has very skilled engineers, makes great strides in security, and I'm impressed by their hardware skills.

However, UX is their weakness. I don't know why we keep pretending that UX is Apple's strength. Have you used their window manager? Have you used their workspace implementation? Clearly they haven't used it themselves. Everything about the Mac UI is geared toward just having a pile of windows in one workspace.

Their window switcher by default requires switching between applications then switching between the windows of that application. Why?

Rearranging the contents of workspaces is a complicated dance of swipes and drags and other mouse-heavy movements. On a decent window manager, this can all be done with keyboard shortcuts.

They neglect power-users. They neglect usability for those with limited range of motion.
