Note that in actual usage, the Touch Bar will only be changing substantially when you switch between apps/contexts or are interacting with it. From the Touch Bar HIG at https://developer.apple.com/library/content/documentation/UserExperience/Conceptual/OSXHIGuidelines/AbouttheTouchBar.html https://developer.apple.com/library/content/documentation/Us...: Use the Touch Bar as an extension of the keyboard and trackpad, not as a display. Although technically it’s a screen, the Touch Bar functions as an input device, not a secondary display. The user may glance at the Touch Bar to locate or use a control, but their primary focus is the main screen. The Touch Bar shouldn’t display alerts, messages, scrolling content, static content, or anything else that commands the user’s attention or distracts from their work on the main screen.
