I've recently switched from windows to Mac and it was so refreshing using a system that does not purposely work against the user. I don't agree with many design decisions in Mac (wtf is up with tabbing into apps I've closed, or not being able to tab through instances of an app without a separate shortcut?!) but at least they're not shoving telemetry and ads down your throat.
(many) apps keep running without windows — all you closed was the last open window. cmd-~ switches between windows within a running app. this has been the case since the classic Mac days, & while it seems to drive those who come from Windows bonkers, long-term Mac users (at least all I've known) appreciate this small aspect of macOS as it makes a clear distinction between apps & windows. newer apps (some from Apple) which break this model are still maddening to use.
You must be using a different macos than me, or have not attempted to connect a mouse (Scroll Reverser), an external display (BetterDisplay), wanted to have sane power management (Amphetamine), want to reach all application windows with only the keyboard, wanted to close modal popups with only the keyboard, etc...
About telemetry, and ads: It is also present in MacOS, but less invasive indeed. And about not showing something down my throat: the other day my iphone just told me in declarative, with a single accept button: now your system will be updated to ios27 (download of updates was enabled, with manual confirmation).
Also having to unlock every app after every brew update in the applications as they "have been downloaded from the internet"... it is not something i'd call refreshing and not working against me.
