Apple has seeded a new beta of its upcoming OS X Yosemite 10.10.2 this evening. The update, labeled build 14C99d, is available through the Update tab in the Mac App Store and the Dev Center for all registered Mac developers.
Today’s release comes just a week after the previous OS X 10.10.2 beta, and Apple has again asked developers to focus their testing efforts on Wi-Fi connectivity—a long-standing Yosemite issue—as well as Mail and VoiceOver.
