any lack of ability to find something in the most efficient way is always 100% the user not knowing the system.
A mac is no more intuitive, it's all about what you're used to.
Sorry, but if you can find something because YOU KNOW where it is, doesn't mean a thing. It's about being able to find shit when you have no idea where it is, but the interface is designed in such way that enables you to find it quickly. Control panel in windows is a massive mess of links, help tips and descriptions that is only comparable to windows registry.
Preferences in OS X don't have submenus that go in 5 levels deep and show you 'helpful' tips, that's why it's easier to use. If you need advanced settings, you have command line for it. Command line in windows is an abomination since it's birth so all configuration has go through those poorly designed, 15 years old settings screens that never show you what you need and won't ever be streamlined because microsoft doesn't give a fudge.
Your way of thinking is that "If you can't find something then you're clearly too stupid to use it anyway". Stick to it, it will serve you well.
I, myself, prefer "If you can't find something then clearly I've done a poor job designing it. I'll do it better next time". I'll stick to that.
The primary function of the design engineer is to make things difficult for the fabricator and impossible for the serviceman.
