iTunes Sync – The light grey tracks have failed to copy across to an iPhone. If the above screen is a familiar sight, then you’ll be painfully aware that since Apple updated its iTunes software to version 11.1.3 there have been problems syncing music to an iOS device. Don’t worry, you’re not alone. The web is currently awash with people bemoaning the fact they can’t change the music on their iPhone. Indeed, my iPhone 5 was affected by this. Thankfully, after blood, sweat, and a few tears, I managed to find a solution. First, connect your iOS device to iTunes. At the bottom of the Summary page you’ll see a multi-coloured bar. This illustrates how your iOS device’s memory is being used. As you can see from the screen below Audio and Other were the most prominent on my iPhone.
