Out of the box macOS doesn't have a button to maximize the way Windows does. The green button in modern macOS is for full-screen and option-clicking that button will bring back the old "zoom" behavior which expands the window to fit the content being displayed. It's a lot less frustrating of an experience when you realize that the button doesn't do what you assume it does.

I'm not talking about macOS's green button. That doesn't maximize windows: it creates a dedicated workspace which might have one or two windows.

I've referred to macOS's "maximize window" feature, which you trigger by double-clicking a window's title bar.
