The MacBook Pro is a line of Macintosh
portable computers introduced in January 2006 by Apple Inc.
It replaced the PowerBook G4 and was the second model to be announced
in the Apple–Intel transition (after the iMac). Positioned at the high end of the
MacBook family, the MacBook Pro is currently produced
in three sizes: the 13-, 15-, and 17- inch.
There have been two designs for the MacBook Pro, both using aluminum.
The first design was largely a carry-over from the PowerBook G4 and used the
Intel Corecentral processing units as opposed
to the PowerPC G4 chips used in the model it replaced.
It was first released as a 15-inch model in January 2006,
followed by a 17-inch model in April of the same year.
These original models received several updates and
were upgraded with Core 2 Duo processors in late 2006.
The second "unibody" model has a more tapered
design with most of the casing made from a single block of aluminum.
This design was introduced with the 15-inch MacBook Pro in October 2008,
along with the 13-inch aluminum unibody MacBook.
The 17-inch model was updated with the same design the following January,
also introducing the built-in battery that was later used
in the rest of the MacBook Pro line from June 2009.
Subsequent updates brought upgraded Intel Core i5 and i7processors
and introduced Intel's Thunderbolt technology.
