The Power Macintosh (later Power Mac) is a family of personal computers that were designed, manufactured, and sold by Apple Computer as part of its Macintosh brand from March 1994 until August 2006.


Described by Macworld magazine as "The most important technical evolution of the Macintosh since the Mac II debuted in 1987," the Power Macintosh was Apple's first computer to use a PowerPC RISC processor. Existing software written for 68k processors that were used in earlier Macintoshes would not run on the PowerPC natively, so a Mac 68k emulator was included, starting with System 7.1.2. While the emulator provided good compatibility with existing Macintosh software, initial performance was about one-third slower than comparable Macintosh Quadra systems. The Power Macintosh replaced the Quadra at the high end of Apple's lineup, and were initially sold in similar enclosures, but with 4-digit model numbers. As PowerPC-native software began to appear, significant performance improvements were realized.

Photoshop 3.0 was the first PowerPC-native application from Adobe.

Evolution and discontinuation[]

Over the next twelve years, the Power Macintosh evolved through a succession of enclosure designs, a rename to "Power Mac", five major generations of PowerPC chips, and a great deal of press coverage, design accolades, and controversy about performance claims. The Power Mac was discontinued as part of Apple's transition to Intel processors,[1] which occurred while Macromedia was being acquired by Adobe Systems in 2005.[2] Adobe Creative Suite 3 added support for multi-core Intel-based Macs, and Creative Suite 4 dropped support for PowerPC entirely.
