Adjust application menu on to MacOS

[PhilippMa]

Is your feature request related to a problem? Please describe.
On MacOS, the menu behind the application name usually contains some standard menu items such as "About" or "Quit". However, we currently have the "File" menu sort of hidden here.

Describe the solution you'd like
Add a standard menu behind the app name menu item and have the "File" menu separately next to it.
