Mostly Mac. If apple were to come out tomorrow with friendly repair, driver support, and can be deployed on any hardware - Microsoft would be done. It would only be Google and apple. If I could simply just install osx on my desktop PC, I'd use it.
macOS (and Apple's macOS applications) have been on a slowly accelerating downward spiral too for the last 5..7 years, maybe not as obvious as Windows, but for a long time Apple user it's definitely noticeable.
