Not that I badly want to enable the classic startup chime on newer Macs, I have indeed missed this unique sound ever since Apple removed it in 2016. While a few hacks about getting the chime back on macOS surfaced online, their joy was short-lived as macOS updates rendered them useless. But guess what, an all-new Terminal command trick, which brings back the startup chime quite reliably, has been getting plenty of traction for the past few days. If you wish to get this iconic sound on your Mac, let’s unravel this hack right away!

Enable the Classic Startup Chime on Newer Macs

For those unfamiliar, the chiming startup sound was actually (C-major chord) developed to let macOS users know that the diagnostic tests didn’t find any software or hardware issues. And it had existed on almost every Mac boot since 1991.  One more thing worth noting is that the most recent F-sharp chord had first forayed into iMac G3 (1998) which was the first consumer-facing product to launch under the recently returned CEO Steve Jobs. Moreover, G3 proved to be a game-changer for Apple, saving the company from the impending financial ruin in the late 1990s. Now that you’ve got a fair amount of history behind this iconic sound, let’s get on with the quick steps!

1. Launch the Terminal app on your Mac.
