Today Apple previewed the next major revision to its macOS operating system, macOS 10.14 Mojave. In addition to increased performance, improvements to the operating system include a systemwide dark mode and key changes to the Desktop and Finder. Mojave also has new core Apple apps such as News, Stocks, Voice Memos, and Home, which are part of a previewed multi-year project to bring native iOS apps to macOS. Other previewed updates are Dynamic desktop, desktop Stacks, Continuity camera, group FaceTime, and Siri shortcuts. Finally, Apple has completely redesigned the Mac App Store and provided new privacy and security features. A Developer Preview version will be available immediately for registered Apple Developers, with a Public Beta expected in July. The developer preview of macOS Mojave is available to Mac Developer Program members starting today. To help make macOS even better, Apple is also providing a macOS Public Beta Program, which gives customers early access to macOS Mojave and invites them to try out the release and submit their feedback. Mac users can participate in the Apple Beta Software Program for macOS Mojave this July and download the final version for free from the Mac App Store this fall. In order to download and test out macOS Mojave, you must be a registered and paid member of the Apple Developer Program. Please note, our rules prohibit discussion of the Developer Beta, but will allow discussion of the Public Beta when it is available. This site allows discussion of pre-release software (such as macOS Public Beta software builds) from the free Apple Beta Software Program. This site does NOT support pre-release Apple Developer Program Beta software, and does NOT allow the discussion of installation or use of Apple Developer Program Beta software. Repeated violations of this rule will result in a permanent ban. No Apple Developer Program Builds, Apple Beta Software Program builds only.
