The sound is the familiar startup tone associated with MacBook laptops from the era before 2020, when Apple computers were widely recognised by that brief chime at power-on. It became a shorthand for Apple in tech videos, unboxings and parodies, where a few seconds of audio could instantly tell viewers a Mac was booting up. Even as newer Macs changed their startup behaviour, creators kept using the older chime for nostalgia, clean tech intros and jokes about Apple products, keeping it recognisable long after it stopped being the everyday sound.
