Previewed at WWDC, launching in the fall.
Apple Seeds Second Beta of macOS 10.14 Mojave to Developers
macOS Mojave introduces a new method of installing software updates, so after you've installed the first beta from the Apple Developer Center, additional betas can be downloaded clicking on the Apple in the menu bar, choosing "About This Mac" and clicking "Software Update." Alternatively, open System Preferences and choose the "Software Update" icon.
The macOS Mojave update introduces a long-awaited and much-desired systemwide Dark Mode, with Mojave users able to choose between a light theme or the new dark theme. Dark Mode is accompanied by Dynamic Desktops, aka wallpapers that subtly change throughout the day.
Stacks, a new Desktop organization system, keeps all of your desktop files nice and neat, while Finder has been enhanced with a Gallery View, a Sidebar, a revamped Quick Look option and Quick Actions, so you can do more in the Finder window than ever before.
Screenshots can now be edited using Markup tools, while Continuity camera, a new feature, lets you import photos and document scans directly from the iPhone to the Mac.
Apple News, Stocks, Home, and Voice Memos apps have been ported from iOS to macOS as part of a multiyear project Apple is working on to make it easier to port iOS apps to Macs, and Apple has introduced several privacy protections to keep your data safer.
Apple is also making it harder for websites to track you with a range of new tools, plus there's an entirely revamped Mac App Store that makes it easier to discover apps.
macOS Mojave will be beta tested by developers and eventually public beta testers for several months so Apple can work out bugs and other issues before releasing the software to the public in the fall.
