Apple has seeded OS X Yosemite Developer Preview 7 to developers today, coming two weeks after the sixth Developer Preview. The new operating system debuted three months ago at Apple’s annual Worldwide Developers Conference.
The update is available only to registered developers via the Mac App Store, and the Mac Developer Center. A new version of Xcode 7, an OS X Server 4.0 Developer Preview, and an updated version of Apple Configurator 1.7 were also released.
