The first menu item Delphi FMX TMainMenu is not displayed in OSX, OK in WIndows

Question

I created a Multi-Device app in Delphi Seattle and added TMainMenu with MenuItem1 and MenuItem2 (nothing more). When creating and starting OSX, only MenuItem2 is displayed. When creating and starting Windows, both menu items are displayed. I did not consider two menu items differently. Both were added and not configured in any way. Does anyone else experience this?

The top-level items on the Mac menu bar usually look like this:

Apple/system menu ('About this Mac', 'System Preferences...', etc.)
Application menu ('About XXX', 'Services', 'Hide XXX', 'Hide Others',
  'Show All', 'Quit XXX')
File menu
Edit Menu
...

FMX ( ) TMainMenu . , ( - ), OS X; Mac. , (TFileHideApp, TFileHideAppOthers, TFileExit). , :

• , TActionList

procedure TForm1.FormCreate(Sender: TObject);

end;
