At the company's Worldwide Developer Conference on Monday, Apple software engineering chief Craig Federighi unveiled technology that will make it easier for people who've written software for iPhones and iPads to bring those apps to Macs. It's only a peek for now, but Apple's four apps built with the technology -- News, Stocks, Voice Memos and Home -- will arrive later this year with MacOS 10.14 Mojave. And in 2019, Apple will bring the technology to outside developers, too.

The result could mean a massive infusion of new software. In the personal computer market, Macs are scarcer than machines powered by Microsoft Windows, and the rising use of Google's Chrome OS-powered Chromebooks isn't doing Apple any favors, either. Opening Macs up to the enormous number of iPhone and iPad software developers, though, could make Macs much richer.
