Following Apple's announcement last month that it would be updating its 12-inch Retina MacBook line, the company is now reportedly set to refresh its MacBook Pro range with a thinner and lighter design, as well as introducing some surprising new hardware features.

According to respected Apple analyst Ming-Chi Kuo at KGI Securities (via 9to5Mac), Apple plans to introduce 13-inch and 15-inch MacBook Pro models in the fourth quarter that will see the physical function keys along the top of the keyboard replaced with a new "OLED display touch bar." The laptops will also feature a new, smaller metal-injection molded hinge.

Additionally, Apple is said to be introducing its fingerprint scanning Touch ID feature - currently only available on iOS devices - to its new family of MacBook Pros. Not only would this remove the need to type in a password, but it could also have other uses, such as making online purchases with Apple Pay.

The new MacBook Pro line will take some design cues from the 12-inch MacBooks, and support the USB-C standard. But unlike those 12-inch laptops, the new Pros will come with Thunderbolt 3 support.

There are also reports that Apple will introduce a new 13-inch MacBook similar to the recently upgraded Retina models. According 9to5Mac, Apple "plans to make the MacBook Air the entry-level option, while the MacBook will become the mid-tier choice and the MacBook Pro will remain the high-end variant."

Apple hasn't updated its MacBook Pro range since 2012, so a refresh is long overdue. While the rumored updates do seem quite major, much of Kuo's Apple-related news has proved accurate in the past.
