The Power Mac G4 (AGP Graphics), introduced in 1999, was historically significant because it was the first Macintosh to use Apple’s new “Sawtooth” tower design, which became one of the company’s most recognizable professional desktop forms of the early 2000s. It also marked Apple’s push to position the G4 as a high-performance machine for graphics, video, and creative work, helping define the Mac as the preferred platform for many design and publishing professionals at the turn of the century.
