Apple's announcement of macOS Mojave introduces several new features and enhancements aimed at improving user experience and security. The operating system includes a dark mode and Desktop Stacks for organizing files, dynamic desktop backgrounds, and an updated Finder with enhanced file handling capabilities. Mojave also brings a redesigned Mac App Store similar to iOS, updated screenshot tools allowing for screen recording, and significant security improvements, such as limiting data access by third-party companies and enhancing Safari's protection against cross-site tracking. While integrating some iOS frameworks into macOS, Apple maintains that a full merger of iOS and macOS is not planned, but classic iOS apps like News and Stocks are now available on Mojave. Additionally, the release excites iOS developers, as testing on macOS Mojave is facilitated by platforms like LambdaTest, which promises support within three weeks.
