Touch Bar

Touch Bar (2016–2021)

Apple unveiled Touch Bar 13-and-15-inch (330 and 380 mm)ch MacBook Pro models during a press event at their headquarters on October 27, 2016. All models, except for the baseline 13-inch (330 mm) model, featured the Touch Bar, a new multi-touch-enabled OLED strip built into the top of the keyboard in place of the function keys. The Touch Bar is abutted on its right by a sapphire-glass button that doubles as a Touch ID sensor and a power button. The models also introduced a "second-generation" butterfly-mechanism keyboard whose keys have more travel than the first iteration in the Retina MacBook. The 13-inch (330 mm) model has a trackpad that is 46% larger than its predecessor while the 15-inch (380 mm) model has a trackpad twice as large as the Retina models.
