As earlier leaks already revealed, the new MacBook has an OLED touch panel on top of the keyboard. This "Magic Toolbar" replaces the traditional function keys and it also seems to have an integrated fingerprint scanner.
Thickness can't be determined from the orientation of the MacBook Pro in the images, but rumors suggest the new machine is thinner and lighter weight than existing models. A redesigned hinge can be seen in the images, suggesting it is indeed quite a bit thinner. Also visible are much flatter keys, similar in design to the keys of the Retina MacBook, which use a new butterfly mechanism.
Ports are not visible, but based on past part leaks, we're expecting four USB-C ports and a headphone jack, with the HDMI port, MagSafe port, and SD card slot being eliminated.
