Updated from 12:39 p.m. to include announcements. NEW YORK ( TheStreet ) Apple ( AAPL ) kicked off its Worldwide Developer Conference today, where it made several big software announcements, but no new hardware announcements, in light of a major product refresh and update later this year. This year's WWDC, held in the Moscone Center West in San Francisco, focused on iOS 8, as well as Mac OS X, codenamed Yosemite. Yosemite continues to converge with iOS, looking more like Apple's mobile operating system, but it's still separate enough to be distinct. As part of OS X Yosemite, Apple announced new features like Spotlight search, making online and offline search easy, straight from the operating system. It also enhances iCloud for Mac OS X using iCloud Drive, which allows users to store files of any type, and find them anywhere, including iOS, Mac OS, and even Microsoft ( MSFT ) Windows.
