MacOS 10.15: Slow by Design (2020)
What a nightmare. My previous two jobs had me use macOS, specifically Macbook Pros, and it was a nightmare. Slow, difficult to even use the computer due to all sorts of hidden behaviors and blocks, and a terrible mess when it came to my external monitor, webcam, keyboard, and mouse (from major brands in Dell and Logitech). I got to choose for my new job and chose Windows, and it's night and day in terms of productivity.
