How to prevent Terminal.app from displaying a tab bar when there is only one tab open The image below is the header that appears when I open Terminal.app.  As you can see, only one tab is open, but a tab bar still shows (just has one tab that says "bash").  How can I prevent the tab bar from showing unless there are >= 2 tabs?  It was working correctly until recently but I can't figure out what changed or how to fix.
Click "View" / "Hide Tab Bar" and the tab bar will go away and come back only when there is more than one tab open.
