Saying Apple Software is 'terrible' is a blatant hyperbole. Has it degraded meaningfully over the last decade in terms of stability? Yes. Has it's capability increased though? Yes. Has it become more secure by design? Yes. Is the UX better than anything else in market? By a country mile.
The UX used to be better by a country mile. The liquid glass update was a genuinely serious regression. Is Windows or Android now better? At least those operating systems don't have constant contrast issues and flickering. At this point they probably have more consistency.
MacOS reliability has slowly gotten worse and worse, but the UX drop with liquid glass was profound.
