The Touch Bar places controls right at your fingertips and adapts to different apps to provide useful functions without having to navigate complex menus or memorize keyboard shortcuts. Replacing the function keys in the top row of the keyboard, the Touch Bar features a Retina-quality display and supports multi-touch input.
The power button has been upgraded with a Touch ID sensor, so you can quickly log into your MacBook Pro using your fingerprint. You can also use Touch ID to make purchases over the web, thanks to Apple Pay. Touch ID enables a quick, accurate reading of your fingerprint and uses sophisticated algorithms to recognize and match it with the Secure Enclave in the Apple T1 chip.
The system features a 2.7 GHz Intel Core i7 quad-core processor, 16GB of 2133 MHz LPDDR3 onboard memory, a 512GB PCIe-based SSD, four Thunderbolt 3 (USB Type-C) ports, a 50% larger Force Touch trackpad, a keyboard with a 2nd-gen butterfly mechanism, stereo speakers with double the dynamic range of its predecessor as well as improved bass, 802.11ac Wi-Fi, Bluetooth 4.2 wireless technology, and even a 3.5mm headphone jack. macOS Sierra is the installed operating system.
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, thanks to macOS Sierra.
The 15.4" Retina Display has a 2880 x 1800 resolution and features brighter LED backlighting than its predecessor as well as an increased contrast ratio, delivering deeper blacks and brighter whites. Its larger pixel aperture and variable refresh rate make it more power efficient than previous generations. It also supports the P3 color gamut, which allows for more vibrant colors. This ensures true-to-life pictures with realistically vivid details, which are essential for graphic design, color grading, and editing.
