Apple Unveils New Operating System Dubbed “Yosemite”

Apple today unveiled the next version of its Mac OS X operating system. 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 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 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.
