macOS Mojave Coming This Fall

The new Stacks feature organizes messy desktops by automatically stacking files into neat groups. Familiar iOS apps, including News, Stocks, Voice Memos and Home, are now available on the Mac for the first time. FaceTime now adds support for group calling, and the Mac App Store gets a full redesign featuring rich editorial content and the addition of apps from top developers, including Microsoft and Adobe.
