I switched from Linux to Mac OSX when they started to use Darwin Kernel.
I liked the screen quality, user experience and longevity. I could keep my iMac for ten years without problem.
But it recently broke and fixing it is a nightmare 
Not so user friendly when it comes to change internal components.
As I don’t use any Mac software, don’t play music, don’t edit video I am completely at ease on Linux, and will wait if new chipset is worth on desktop Mac too.
