Use the laptop identification system to help you identify your machine. MacBooks tend to look very similar, and it's important to know which machine you have before ordering any replacement parts.

The MacBook Pro 17" Mid 2011 Unibody's case is composed of a single block of aluminum, following the same process of the MacBook Unibody and the MacBook Pro 15" Unibody. The Unibody revision also introduced some features that were never before seen on an Apple laptop: the inclusion of dual video cards (one for regular use, one for graphics intensive applications), the Mini DisplayPort (which replaced the full-size DVI display connector), and larger hard drive and RAM capacities.

The MacBook Pro 17" Mid 2011 is one of the first Apple laptops powered by an Intel quad-core i7. It features an AMD Radeon HD graphics processor. The newest addition to the family is Intel's new high-speed connector technology called Thunderbolt. Thunderbolt is supposed to transfer data at a rate of 10 gigabits per second. It can also be used to connect computers to external monitors and transfer data at the same time, all with a single cable.
