Power Macintosh, later Power Mac, is a line of Apple Macintosh workstation-class personal computers based on various models of PowerPC microprocessors that was developed, marketed, and supported by Apple Inc. from March 1994 until August 2006. The first models were the Power Macintosh 6100, 7100, and 8100, which offered speeds ranging from 60 to 110 MHz. These machines replaced Apple's Quadra series of personal computers, and were housed in cases very similar to systems sold by Apple up to that point. The Power Mac went on to become the mainstay of Apple's top-end offerings for twelve years, through a succession of case designs, four major generations of PowerPC chips, and a great deal of press coverage, design accolades, and technical controversy. In August 2006, the Power Mac's retirement was announced at Apple's Worldwide Developers Conference by Steve Jobs and Phil Schiller, making way for its replacement, the Mac Pro.

[edit] Naming

All Power Macs prior to 1997 used PowerPC 60x-series processors, and 4-digit model numbers (e.g. Power Mac 8600). In 1997 the first third-generation ("G3") Power Macintosh was introduced, using the PowerPC 750 processor. From this model onward, Apple no longer used a numbering scheme to identify their Power Mac models, but instead referred to them by their PowerPC processor generation number (i.e. G3, G4, and G5). Later models based on the same generation of PowerPC processor relied on descriptive characteristics to differentiate them, e.g. the color scheme ("Power Macintosh G3 - Blue and White") or a technical feature of a particular model ("Power Mac G4 - Gigabit Ethernet"). This same identification scheme was used in the iMac, PowerBook, and iBook lines of Macintosh computers.

The marketing name was changed from Power Macintosh to Power Mac with the introduction of the G4 models, meaning all G3 and earlier models are Power Macintoshes, while all G4 and G5 models are Power Macs. Not all Apple documentation follows this rule, but the vast majority does.

[edit] Usage

The "Power Mac" brand name was used for Apple's high-end tower style computers, targeted primarily at businesses and creative professionals, in differentiation to their more compact "iMac" line (intended for home use) and the "eMac" line (for the education markets). They were usually equipped with Apple's newest technologies, and commanded the highest prices among Apple desktop models. Some Power Mac G4 and G5 models were offered in dual-processor configurations. Other past Macintosh lines that have used PowerPC processors include the Macintosh Performa, iMac, iBook, and PowerBook 5300 and later models.

[edit] Advertising and marketing

Apple introduced the Power Mac series of high-end personal computers aimed at businesses and creative professionals in 1994 with an advertising campaign consisting of several television commercials and print ads. The television commercials used the slogan "The Future Is Better Than You Expected", featuring the first three Power Macintosh computers to showcase special features such as networking and MS-DOS compatibility.

[edit] Processor and software

The ROM and Mac OS operating system released with the new Power Mac machines included an Mac 68K emulator to enable programs written for Motorola 68k series CPUs, including nearly all prior Mac software, to run without changes. (A similar scheme is employed to run 68K software on modern x86 Alpha Microsystems machines.) As the Power Mac was originally intended to be a part of the high end of Apple's product line, for a number of years the company continued to offer less expensive 68k-based computers alongside the more expensive Power Mac lineup. However, for many of these so-called 68K transition Macs, Apple offered an upgrade path in the form of a PowerPC Macintosh Processor Upgrade Card and aggressively marketed it to assure a wary consumer of their investment. In April 1996, Apple discontinued the Macintosh LC 580 (released in 1995), the last remaining desktop model of the 68k-based Macintosh line. The PowerBook 190cs, the last 68k-based PowerBook, was discontinued in October of 1996. All subsequent Macintosh computers would be based on PowerPC processors until 2006, when Apple switched to Intel processors.

[edit] Successor

The Intel-based successor of the Power Mac is named the Mac Pro, in line with the renaming of their professional notebooks from PowerBook to MacBook Pro.
