The new release, called OS X Yosemite after the famed national park, includes a largely redesigned user interface more closely aligned with the look of its mobile iOS software. Craig Federighi, Apple’s software engineering chief, took the stage of the firm’s annual [Worldwide Developer’s Conference](http://fortune.com/2014/06/02/apple-wwdc-liveblog/?xid=timerail "undefined") to show off the software. The new version, which features a sharper, flatter look, is more similar to the iOS software that runs on iPhones and iPads than any previous version of the Mac operating system. OS X Yosemite also includes a “Dark Mode” that minimizes the translucency effect and introduces a darker color palette. Executives previewed changes to the software’s Notification Center, Spotlight search, Maps, Calendar, Messages, and Safari web browser. A system dubbed “continuity” is intended to allow iOS devices and Macs to communicate seamlessly. A user can, for example, begin composing an email on an iPhone and automatically finish writing it on a nearby desktop computer. The system can also be used to place and answer phone calls and text messages that come to a phone on a nearby computer. To show off the feature, Federighi placed a call from his desktop to new Apple employee Dr. Dre. “How you doing this is Dre,” said the rapper who is joining the company as part of a [$3 billion deal](http://time.com/132644/apple-beats-electronics-headphones/ "undefined") for headphone-maker Beats Electronics. “Thanks for creating such amazing apps,” he said. “Say, what time should I show up for work?” Apple made a developer preview available to conference attendees today. It will be available for free to all users this fall. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/2809853/apple-mac-os-x-yosemite/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/2809853/apple-mac-os-x-yosemite/"},"headline":"Apple Unveils New Operating System Dubbed \"Yosemite\"","datePublished":"2014-06-02T17:48:35.000Z","dateModified":"2026-04-13T08:02:22.540Z","description":"Apple today unveiled the next version of its Mac OS X operating system.
