The Mac startup chime is associated with Apple Macintosh computers and plays during the boot process on supported models. It became one of the most recognizable computer sounds, helping turn an otherwise ordinary startup routine into a memorable brand cue. As older Macs became nostalgic objects, recordings of the chime spread through video edits, memes, soundboards, and technology-themed posts. Its brief length and clear tone make it useful online as an audio transition, a retro-computing reference, or a quick signal that a device has powered on.
