I put Windows 10 on my old MacBook Pro and was shocked by how much more responsive it felt in Windows than in macOS. I thought the hardware was just too old because it was starting to feel sluggish in macOS, but Windows runs perfectly well on it.
Maybe Apple can continue to evolve their hardware fast enough that their software doesn’t need to be as efficient, but share your feelings that we’d all be better off if Apple had made responsiveness a priority.
