Apple packed so many announcements into its WWDC 2024 keynote that MacRumors condensed the lot into a nine-minute video. For the Mac, the headline was macOS Sequoia, also called macOS 15.
TechCrunch picked iPhone mirroring as one of the biggest additions. Through Continuity, the iPhone screen shows up on the Mac and can be controlled from there. Audio comes through the Mac. Notifications on the Mac bring up the mirror mode. The catch: the paired iPhone stays locked.
The rest of the list
Sequoia also adds automatic window tiling, plus a presenter preview mode for video calls that includes built-in background replacement. A new cross-platform Passwords app comes with the Keychain upgrades. MacRumors listed two privacy items: a “Rotate Wi-Fi Address” option meant to cut down on tracking, and a way for websites and apps to update existing logins to passkeys automatically.
Safari gets Highlights, which uses AI to spot interesting things on a page. Reader mode now offers AI-powered summaries and tables of contents. A Viewer option brings videos front and centre with system video controls.
Developers get Game Porting Toolkit 2, with improved Windows compatibility and better debugging tools.
Timing
The developer beta is out now. A public beta is due in July, and final releases arrive in the fall.
MacRumors also pointed readers to a separate piece on which Macs and iPads lose support under macOS Sequoia and iPadOS 18, which matters to anyone running older hardware. The keynote introduced Apple Intelligence, iOS 18, iPadOS 18, visionOS 2, watchOS 11 and tvOS 18 too.
