The Mac Pro is a workstation computer manufactured by Apple Inc.. The machines are based on Xeon microprocessors, but are similar to the Power Mac G5 they replaced in terms of outward appearance and expansion capabilities. The Mac Pro, in most configurations, is the fastest computer that Apple offers and one of three desktop computers in the current Macintosh lineup, the other two being the iMac and Mac Mini.

The first Mac Pro was based on dual Dual-core Xeon Woodcrest processors and formally announced on August 7, 2006 at WWDC. A new Intel Xeon-based Xserve was announced along with the Mac Pro, completing Apple's transition from the PowerPC to x86 architecture.

On April 4, 2007, a dual Quad-core Xeon Clovertown model was launched and it was replaced on January 8, 2008 by a dual Quad-core Xeon Harpertown model. The current model Mac Pro was announced on July 27, 2010 and features Intel Xeon processors based on the Nehalem microarchitecture/Westmere microarchitecture. There are options of up to 12 processing cores, up to four optional 2TB hard disk drives/512GB solid state drives and ATI Radeon HD 5770/5870 graphics.
