When you buy a MacBook Pro you get a narrow touchscreen display at the top of your keyboard that charges as you move between apps. You can customize this Touch Bar to have it display things like F-keys, system controls, desktop switching and more. Even some of the app-specific controls themselves can be customized.
I've a new MacBook for 9 months. It has been more perplexing than useful. I need this video 9 months ago. Thanks!
Excellent instructional video Gary. I had no idea that the functionality and customization of the touch bar was so vast.
