Added to the MacBook Pro in 2016, the Touch Bar is a small touch screen panel on the keyboard of both the 13-inch and 15-inch MacBook Pro models. The Touch Bar entirely replaced the function keys found on previous models keyboards and can be used for shortcuts in programs that support this feature.
While not all Mac users miss function keys, many people dislike the Touch Bar because of the missing Esc key and the frequent occurrence of mistakenly pressing a button like the Siri button.
