The Macintosh 128K launched in January 1984 as Apple's first Macintosh, and its startup chime became one of the earliest recognisable computer sounds. As Macs spread through schools, studios, and homes, that boot tone turned into shorthand for personal computing itself. Clips and soundboards later preserved it alongside later system sounds like Windows XP error music, keeping it alive long after the hardware faded. It remains popular because a single second instantly signals retro technology, a fresh start, and the early home computer era.
