It’s been a year since one of Apple’s chief techies – Scott Forstall – left Apple, and was replaced by Jony Ive and Craig Federighi, who were supposed to manage both iOS and OS X. This was meant to give Apple a chance to create a single, unified design across all operating systems. Apple followers will have expected OS X Mavericks to be quite similar to the new iOS – for the software to merge seamlessly between mobile and desktop device.
