A fair number of MacBook Pro users with Touch Bar equipped Macs have discovered the Touch Bar stops working or goes black after installing a MacOS update. Given that the Touch Bar serves as Function keys, F1, F2, F3 etc keys, as well as toggles for adjusting brightness, system audio, and accessing many MacOS and app features, and even serves an Escape key for some Touch Bar Macs, having the Touch Bar vanish and fail is not particularly great. Even if you disabled the Touch Bar to have it simply display system toggles, having it disappear completely is still frustrating, because there’s no other way to access those toggles on the keyboard.
If your Touch Bar is not working or the Touch Bar vanished on your MacBook Pro, particularly after installing a system software update to MacOS, read along to troubleshoot the issue.
