Touch Bar shows: Click the pop-up menu, then choose what you want the Touch Bar to show - for example, app buttons or the expanded Control Strip. On your Mac, choose Apple menu > System Preferences, click Keyboard, then click Keyboard. You can also change what happens when you press and hold the Fn key or the Globe key on the keyboard. For example, you can have the Touch Bar show just the expanded Control Strip or just app buttons. Set options to control what’s shown in the Touch Bar.
