On macOS High Sierra I have install the "emacs-mac" Emacs port via homebrew. The Emacs version now is 25.3.3.

When starting up Emacs I get this strange tab in my Emacs frame:

Useless tab in Emacs frame

I have set the Document tab setting "Prefer tabs when opening documents" in the Dock Preference pane to "Manually". I still have this useless tab.

How can I get rid of it?


A similar question has been posted and solved before here.

More info on the issue can be found under this Github ticket.

So, to answer your question, you can do M-x mac-toggle-tab-bar and toggle with this the tab off.

  • Thanks for the pointer, @spav. However, as a detail mac-toggle-tab-bar is a function, not a variable. I have edited your answer accordingly. (The edit is now in the review queue.) – halloleo Mar 9 '18 at 3:31
