Apple debuted the new MacBook Pro in October with an OLED strip of app specific controls called the Touch Bar. This replaces the function keys with a row of context-sensitive shortcuts.
The Force Touch trackpad was made larger to provide more room for gestures, and the keyboard was also updated with a second-generation version of the butterfly keys found in the 12-inch MacBook. Memory speed in all models except the entry-level 13-inch was upgraded to 2133MHz, and all new models are thinner and lighter.
The ports saw substantive changes, too. You’ll now get either two or four Thunderbolt 3 ports (depending on the model), which are also compatible with USB-C devices, and through which you charge the MacBook Pro. The 13-inch and 15-inch sizes remain, although the entry-level 13-inch lacks a Touch Bar.
