The Touch Bar replaces the function keys that have long occupied the top of your keyboard with something much more versatile and capable. The multi-touch, Retina-quality display changes automatically based on what you're doing, from showing traditional system controls, such as volume and brightness, to more directly interacting with or browsing through content. Intelligent typing features like emoji and predictive text improve the typing experience, and you'll be able to customize the Touch Bar to fit your needs. The Touch Bar can also adapt to apps, such as Mail, Safari, Messages, and even third-party apps like Adobe Photoshop, so you'll have access to useful functions previously hidden in menus.

A Touch ID sensor has been integrated into the power button, so you can quickly log into your account, even when another user is logged in. You can also use it with Apple Pay to securely purchase things over the web.

With the Apple T2 chip, the MacBook Pro delivers enhanced system security with support for secure boot and on-the-fly encrypted storage, and also brings "Hey Siri" to the Mac.
