The PopSugar website summarizes the six new features of the MacBook Pro:
New design:
The new MacBook Pro is expected to be rather thin, but not as thin as a MacBook Air or a 12-inch MacBook. The current model has a 13-inch MacBook Pro thickness of 0.71 inches (1.8 cm).
Farewell function key:
It is said that Apple will use the touch screen instead of a line of function keys at the top of the keyboard. The new MacBook Pro will use OLED screens (possibly for future iphones) to display function keys, such as play keys--related to the software that the user is running.
Using Touch ID fingerprint sensor:
The Touch ID is the fingerprint sensor technology on the iphone and ipad and will be landing MacBook Pro. This means that users use only their fingers to unlock their notebooks without having to enter a password, and it's easier to use the Apple Pay mobile payment.
Faster processors and video cards:
The new MacBook Pro has a much higher processor speed than the 2012 model, and will also configure AMD's Polaris graphics card.
Welcome to USB-C Interface:
The Usb-c interface, which has appeared on the 12-inch MacBook, will be landing MacBook Pro. The Usb-c interface provides a variety of functions: charging, connecting USB and other monitors, and transmitting data.
New color:
The new MacBook Pro will have more colors such as gray, tyrants gold and silver grey.
