The Touch Bar is a multi-touch enabled, interactive OLED strip that replaces the traditional function keys (F1–F12) on the keyboard of certain MacBook Pro models introduced by Apple in 2016. It provides context-specific controls and shortcuts, which change depending on the app or task you’re working on.

- Open terminal
