Apple's Mac startup chime dates back to earlier Macintosh models, but the company removed it from most Macs released after 2016. The sound returned with macOS Big Sur in 2020 and was featured on the M1 iMac introduced in 2021, the first colorful all in one built around Apple Silicon. Recordings clipped from boot up videos and reviews spread quickly on YouTube and soundboards, where the short chime became shorthand for starting a computer, waking up technology, or signaling a fresh beginning in edits.
