Note: The menus are actually there and can be clicked, they just have not labels.

I believe this is because on OS X, menu items in the main menu bar actually display their submenu's title instead of their own title. In other words menuItem.title is ignored, and meniItem.submenu.title is displayed. The following comment, found online, seems to confirm this:

// The titles of the menu items are for identification purposes only and shouldn't be localized.
// The strings in the menu bar come from the submenu titles,
// except for the application menu, whose title is ignored at runtime.

We would need to implement the same in Cocotron.

Somebody, please check if this is also the case for other submenus (that are not direct children of the menu bar menu).

Checked myself, and it's not the case.
