It's very diffierent in the Apple ecosystem in my opinion. People are usually nonchalant, even excited about upgrading. I think that's how Microsoft want people in the Windows ecosystem to feel, but it's just not refined enough for that to happen.
That's not my experience at all. People are just as wary about upgrading Apple devices. I've seen it among friends and family. They're afraid things will break or their device will slow down or everything will move around and they'll have to relearn how to use their device again.
And rightfully so. iOS 7 upgrade turned my iPhone 4S from blazing fast to a slow molasses, and there was no way back. At least you can downgrade most OSes (not sure about macOS).
