The app installation is still the same "ikea dmg app dragging", and occasional zip or pkg. The Finder window already has bookmarks in the left bar. The dock behaves identically. (They went through their weird 3D dock phase but that was... Leopard? I think?)
There is no Mac App Store but barely anyone uses this nowadays anyway... Spotlight... was new in Tiger.
It is much more recognisable than Windows XP vs 11. XP behaves very differently to 11!
