App Window management in Mac OS is beyond infuriating. Time ago it was non existent so you had to download a third party app to enable a clunky version, now it exists but you have to right click on the green dot and hope the snapping menu pops up (sometimes it opens some other menu). I just want MS Windows style “move an app window to the side of the screen and have it automatically snap to take up that half (or quarter)” not the clunky idiotic implementation Apple has provided. The number of hours I have racked up wasting my time resizing and moving windows around manually is obscene.
Also hardware related: the fucking charging port on the magic mouse will go down in history as the stupidest, anti-user design decision in human history.
