How do I disable the Show Tab Bar menu option in Sierra apps? : <p>I've got an app that uses a Toolbar in a NSWindow. I don't want users to be able to customize this toolbar for aesthetic reasons. In Sierra there's a new Menu option that gets inserted into "Menu > View" called <code>Show Tab Bar</code>. How do I disable this? Enabling it only seems to increase the tool bar's height as I don't have extra labels showing under the icons.</p>
