Apple has released an update for OS X Mountain Lion, bringing the latest version of the software to 10.8.3. The new version of the OS brings a number of bug fixes for problems users have been experiencing in 10.8.2 and earlier but also adds new features. The first is that Mac users can now redeem iTunes gift cards using an iSight camera. Now if you take a snapshot of the card in the Mac App Store you can have the system identify its number and redeem it instead of having to type the numbers yourself.
