An anonymous reader quotes a report from CNET: Apple on Monday announced the next version of MacOS. Called Catalina, the next major revision of the MacOS will replace the iTunes app with three dedicated media apps: Apple Music, Apple Podcasts and Apple TV. The update coming this fall will also let Mac users run iPad apps they can download through the Mac App Store. Using the new Project Catalyst development tool, third-party iPad developers will be able to easily bring their iPad apps for the Mac, Craig Federighi, Apple’s senior vice president of software engineering, said. Apple’s goal for developers is to help them build apps without a lot of extra effort that can run on both iOS and MacOS devices. And Mac users will benefit by getting access to an expanded collection of MacOS apps. MacOS Catalina will also let you use an iPad as a second screen. Developer betas for MacOS Catalina and iOS 13 will be available today. Public betas will come in July, and both desktop and mobile OSes will ship in the fall.
