iTunes 11.0.3 is now available. It brings a couple of new features to Apple’s media player. Thanks to the Mac App Store, iTunes is now very easy to install. It’s as simple as launching the store and clicking on updates. Here’s how to do that.
1) Launch the Mac App Store, either through the Dock or the Apple menu.
2) Click on Updates in the upper part of the window (it is usually blue when there are updates available):
3) Click on Update on the far-right. iTunes 11.0.3 will install. It takes about a minute or less on a standard home connection.
4) Once iTunes is installed, you just start listening like you always did before. Easy, right?
