Maybe
http://stackoverflow.com/questions/11494509/nsmenuitem-sethidden-doesnt-work has
the answer

Possible other alternatives to the one in stackoverflow:
 - perhaps disabling the item rather than setting it hidden.

 - or:
 packagedAppEditMenuItem_.reset([[[NSApp mainMenu] itemWithTag:IDC_EDIT_MENU]
copy]);
 RemoveFoo...
 hostedAppEditMenuItem_.reset([[[NSApp mainMenu] itemWithTag:IDC_EDIT_MENU]
copy]);


Try them out. It might also depend how "deep" the -[NSMenuItem copy] is. I.e. if
they point to the same subitem, disabling/hiding it might have implications for
the menu shown when a browser is active.
