I've created a very simple one-window macOS app. All the help text for the app is contained in a single plain text file of less than 500 words. I've set up an action and a view controller to display that text when the Help-AppHelp menu item is clicked. But there's a search field that appears above that menu item. The search field serves no purpose whatsoever, but I can't get rid of it.
I tried deleting the default Help menu and substituting one of my own in the storyboard. But the search field appears again, unbidden. Is there a setting somewhere that will let me disable it?
