One of the biggest announcements primed for Apple’s WWDC 2014 keynote today is the latest update for OS X. Thanks to Mashable’s Lance Ulanoff, we have been given an enticing preview of the real OS X 10.10 ahead of the keynote as he managed to snap a photo of the iMacs Apple will be using to demonstrate the new software. As expected, Apple has seemingly begun to merge the design of iOS with OS X for its latest desktop software, complete with a new dock that should look very familiar to any iPhone owners. We expect to hear plenty more after 1pm once the keynote is underway.
