In two years, the Mac, iPhone, and iPad will be able to run the same apps | Macworld

Apple announced that the company has no plans to merge iOS and macOS during its Worldwide Developers Conference last year, but it also said it’s working on a way for developers to write apps that work on both operating systems. Project Marzipan, as Apple calls it, wasn’t discussed in much detail at WWDC, but Apple described the News, Stocks, Home, and Voice Memos apps that come with macOS Mojave as examples of Marzipan at work. And we haven’t heard a lot about Marzipan since WWDC.
