=== The Power Mac G5 and the end of Power (2003–2006) ===
By the time the [[Power Mac G5]] was unveiled at Apple's [[Worldwide Developers Conference]] in July 2003, Apple's desktop range had fallen significantly behind competing computers in performance.  The G5 closed much of this gap by moving to the [[PowerPC 970]] processor with clock speeds up to 2.0&nbsp;GHz, and a full 64-bit architecture. It also introduced a significantly revised enclosure design, replacing the use of plastics with [[Anodizing|anodized aluminum]] alloy.

Reviews were generally positive. InfoWorld described the G5 as "Apple's best work yet", and said it "delivers on the present need for rapid computing, deep multitasking, and responsive user interfaces — as well as the future need for mainstream computers that rapidly process and analyze massive data sets."<ref>{{cite web

This resulted in the [[Advertising Standards Authority (United Kingdom)|Advertising Standards Authority]] for the United Kingdom banning Apple from using the phrase "the world's fastest, most powerful personal computer" to describe the Power Mac G5 after independent tests carried out by the [[Broadcast Advertising Clearance Centre]] determined the claim to be false.<ref>{{Cite web

Three generations of Power Mac G5 were released before it was discontinued during the [[Mac transition to Intel processors]]. The announcement of the transition came in mid-2005, but the third generation of G5 systems was introduced towards the end of 2005. Most notably in this generation was the introduction of a Quad-core 2.5&nbsp;GHz system. Not only was this the first Apple computer with four processing cores, it was the first to incorporate [[PCI Express]] instead of [[PCI-X]] for internal expansion.<ref>{{cite web

The official end to the Power Macintosh line came at the 2006 Worldwide Developers Conference, where [[Phil Schiller]] introduced its replacement, the [[Mac Pro]].  The G5's enclosure design was retained for the Mac Pro and continued to be used for seven more years, making it among the longest-lived designs in Apple's history.<ref>{{cite web
