Long time Mac user here. A number of my friends in the same boat have complained the quality of the software has started to dip pretty significantly. Can’t say I’m surprised people are looking elsewhere.
I'm surprised macOS is in decline given that their product is pretty good and improving, and it's integrated with popular devices. Still a pretty healthy 16%.
The market share for Linux nearly doubling in a year in the USA is brilliant. Let's hope the trend continues worldwide.
