Although the concept is cool it does tend to run into problems at times, freezing or misbehaving until you’re forced to restart it. If you run into one of these problems, it doesn’t take much to quickly restart the Touch Bar with a Terminal command. If done successfully, the Touch Bar will blink, and then restart, hopefully operating normally once it does. 

  1. Click the Finder icon to open a Finder window.
  2. In Applications, search Terminal.
  3. In the search results, select Terminal.
  4. In the Terminal window, type pkill “Touch Bar agent”.
  5. Press Enter to run the command.
