From its new handoff continuity features to its redesigned, widget-filled Notification Centre, Apple's OS X Yosemite update is set to be a substantial one. Giving a closer look at the touched-up icons, Finder and other features, Apple's now made public this teaser video, first shown exclusively to developers at last week's WWDC conference.
Unless you're a developer, your only hope of getting early access to Yosemite is lucking out with Apple's new OS X Beta Program. Otherwise, you'll have to wait until an unspecified time this Autumn for its full Mac App Store release. Might as well feast your eyes on this for now. [Apple (YouTube)]
