Macbook Pro Aluminum Case Views

Electronics

There have been three separate designs of the MacBook: the original model uses a combination of polycarbonate and fibreglass casing that was modelled after the iBook G4. The second type, introduced in October 2008 alongside the 15-inch MacBook Pro, used a similar unibody aluminum casing to the 15-inch Pro, and was updated and rebranded as the 13-inch MacBook Pro at the 2009 Apple Worldwide Developers Conference in June 2009.[3] A third design, introduced in October 2009, uses a unibody polycarbonate shell as aluminum is now reserved for the higher-end MacBook Pro.

The original MacBook, available in black and white cases, was released on May 16, 2006, and used the Intel Core Duo processor and 945GM chipset, with Intel's GMA 950 integrated graphics on a 667- MHz front side bus. Later revisions of the MacBook moved to the Core 2 Duo processor and the GM965 chipset, with Intel's GMA X3100 integrated graphics on an 800t MHz system bus.[4] Sale of the black polycarbonate MacBook ceased in October 2008 after the introduction of the aluminum MacBook.

The design had stylistic traits of the MacBook Air which were also implemented into the design of the MacBook Pro. This model was thinner than the original polycarbonate MacBooks, and it made use of a unibody aluminum case with tapered edges. The keyboard of the higher-end model was offered with a backlight.

On October 20, 2009, Apple released a MacBook that introduced a new polycarbonate (plastic) unibody design,[35] faster DDR3 memory, a multi-touch trackpad, an LED-backlit display, and a built-in seven hour battery. The polycarbonate unibody MacBook, like its aluminum predecessor, lacks FireWire and, like the 13-inch MacBook Pro, has a combined audio in/out port. On May 18, 2010, the MacBook was refreshed with an updated processor, a faster graphics card, and improved battery life.
