Apple today seeded the third beta of macOS Sequoia to developers. The third beta comes two weeks after the release of the second beta, which brought iPhone Mirroring support.
The developer build of macOS Sequoia can be downloaded by developers through the Apple Developer Center and once the correct profile is installed, succeeding betas will be available through the Software Update mechanism in System Preferences.
iPhone Mirroring allows users to fully control their iPhones via their Mac, providing access to apps, interacting with notifications, and more. A user’s custom wallpaper and icons appear just like on their iPhone, and they can swipe between pages on their Home Screen, or launch and browse any of their favorite apps. The keyboard, trackpad, and mouse on Mac also let a user interact with their iPhone, and audio even comes through. Users can seamlessly drag and drop between iPhone and Mac, and a user’s iPhone remains locked, so nobody else can access or see what the user is doing. It also works great with StandBy, which stays visible, so users can get information at a glance. Additionally, users can review and respond to iPhone notifications directly from their Mac.
All of the Apple Intelligence features coming to iOS 18 will also be available in macOS Sequoia, but Apple does not plan to add these until later in the beta testing process.
As usual, both MacTrast and Apple warn users to not install any betas on their daily driver Mac, instead only installing betas on devices set aside for testing purposes.
