Apple just announced that it will give the public an opportunity to test out OS X 10.10 Yosemite before its official release later this fall. By signing up for the OS X Preview Seed program, you'll receive access to a number of beta versions scheduled to roll out "throughout the summer" according to SVP Craig Federighi. OS X 10.10 features a redesigned user interface partly inspired by iOS, and also packs in several new features including iCloud Drive, MailDrop, and a new continuous client experience between iOS and OS X that Apple calls "Continuity." It will be available for free to consumers in the fall. When Apple unveiled the Beta Seed Program in April, many wondered if it would include test builds of brand new OS X releases. Thankfully for Apple's biggest fans, the answer seems to be a resounding yes.
