Apple Unveils New IOS, OS X Software

UPDATED: The company showcased its new mobile phone software by calling its newest employee, Dr. Dre.

Apple unveiled two big updates to its desktop and mobile operating systems at its Worldwide Developers Conference in San Francisco on Monday. 

Apple CEO Tim Cook started the highly anticipated presentation by sharing some statistics about how Apple's last major software update, Mavericks, has performed. He announced that more than 40 million computers, or more than 50 percent of Apple's install base, have the software installed. According to Cook, Mavericks has performed much better than Windows 8, which has only reached 14 percent adoption. 

Cook then passed the microphone to Apple software chief Craig Federighi, who unveiled the new OS X Yosemite, a significant design update to the software that runs its Mac computers. The update, which will be available in the fall, includes a revamped Spotlight search feature and the new iCloud Drive, a file backup system that syncs with every Mac, iPhone or Windows PC that a person owns.

Federighi showcased the software's new features -- which includes syncing calls through iMessage -- by calling Apple's newest employee, Dr. Dre, who answered the phone and asked what time he should show up for work.

Apple also announced iOS 8, an updated version of the software operating system for iPhones and iPads. New features for the mobile devices include an app bundle called HealthKit that provides a complete picture of a person's vital stats, and a family sharing tool that allows people to share photos, books and movies between devices.  

Other new tools include HomeKit, which turns a mobile device into a remote control of sorts for the home, and a revamped keyboard that includes predictive typing suggestions.  

Apple shares were trading down more than $8 to just over $624 during midday trading immediately following the end of the presentation.
