where is menu bar
In the Macintosh operating systems, the menu bar is a horizontal bar anchored to the top of the screen. In macOS, the left side contains the Apple menu, the Application menu (its name will match the name of the current application) and the currently focused application's menus (e.g. File, Edit, View, Window, Help).
The menu bar in Microsoft Windows is usually anchored to the top of a window under the title bar; therefore, there can be many menu bars on screen at one time. Menus in the menu bar can be accessed through shortcuts involving the Alt key and the mnemonic letter that appears underlined in the menu title.
