Recently I bought a MBP and I'm surprised by how hard to use it is.

Printing by both sides? Not supported, you must do it by hand. And some apps print the pages in reverse order, so you end up having to sort the pages.

Use numberpad . as . instead of ,? You have to download an app to use a sane default.

Alt+. in terminal? No luck if you aren't using an English keyboard.

Run a downloaded app? Run it, accept failure, settings, security, look for blocked app, enable it. It is even worse than Windows Vista.

Give some app permissions? Yeah, you must know which permissions, as you cannot search by app...

And so on...
