Browsers and terminals have "normal menus". Some examples would include Vivaldi and iTerm.

I agree though that placing it on top of the screen (as opposed to the window to which it applies) doesn't make any sense. Windows actually got that right with MDI way back in the day, if you remember how menu merging worked there.

However, there is an unexpected upside to having the menubar there even so. Because macOS apps can't not have a menu bar, they are forced to expose their commands there. Which usually ends up being a more stable UX compared to all the moving around of buttons in the window itself, plus you can search the menus.
