Completely disable or turn off the touchbar on macbook pro

Disabling Macbook Pro's TouchBar isn't natively supported.

As JBallin can tell, the closest answer is to do the following :

• Go onto System Preferences > Keyboard
• Click on Customise Control Strip...
• Remove every item from your control strip

Then set :

• Touch Bar shows | Expanded strip
• Press Fn key to | Do nothing
• Press and hold Fn key to | Show F1, F2, etc. Keys

Now your Touch Bar should light up only after pressing the fn key.

If you still want to completely disable it, have a look at Bar None made by Shaun Inman.
