At its World Wide Developers Conference keynote Monday, Apple made several big announcements, most notably about the long-awaited switch from Intel chips to what the company calls “Apple Silicon.”

But another change was noticed later in the week by developers participating in the WWDC: the iconic Mac startup chime is back.

Multiple users posted to Twitter that the chime has been restored, in the new version of macOS, which is called Big Sur.

According to The Verge the startup chime, which was part of the Macintosh since early in its development, was dropped from Macs in 2016, although one MacBook Air released in 2017 did include it. However, earlier this year someone discovered a systems setting hack that allows users to turn the chime back on.

An Apple Support page also lists what different startup sounds Mac computers make, and what it might mean about something being wrong.

Big Sur, which continues Apple’s recent custom of naming macOS version after places in California, represents the end of macOS X—which had been in use since 2001—and is officially called macOS 11.0. The new operating system includes such changes as new app icons, an updated menu bar, new symbols, and changes to notifications. Big changes were also announced for Safari.

“MacOS Big Sur elevates the most advanced desktop operating system in the world to a new level of power and beauty,” the company said on the macOS website. “Experience Mac to the fullest with a refined new design. Enjoy the biggest Safari update ever. Discover new features for Maps and Messages. And get even more transparency around your privacy.”

The new macOS will be available to download this fall.

Apple’s transition away from Intel chips will take place over two years, and with Intel’s full cooperation. The first Mac computers with the Apple Silicon chips will arrive later this year, Tim Cook said at the keynote.

“With its powerful features and industry-leading performance, Apple silicon will make the Mac stronger and more capable than ever. I’ve never been more excited about the future of the Mac,” Cook said in a statement.
