OS X 10.10, code-named Syrah, us currently sprinting its way towards developer beta for WWDC 2014, which kicks off June 2. Syrah is rumored to be getting a Jony Ive-led interface refresh this year, like iOS 7 got last year. That makes a lot of sense, since part of the opportunity cost of iOS 7 getting all that attention was that there wasn't much left for OS X Mavericks. It shipped with a few rough edges, like stitched leather, shaved off but others, like green felt, remaining. 2014 should see a reversal of those fortunes, with iOS 8 getting refined but Syrah getting a more significant visual upgrade. But how far will it go?
