Apple has improved the integration of iTunes with Apple TV by making it possible now to share photos from any computer in the house and not just the one used as a synchronization device.
Previously, it was only possible to sync the iPhoto or Aperture library for the computer designated as the sync drive with the Apple TV.
For US users, the update incorporates all the necessary options for activating the iPhone, as well as the synchronization of different types of content with the Apple mobile phone.
The system requirements are Mac OS X 10.3.9, or Mac OS X 10.4.7 or later. The update is available through the Software Update feature of Mac OS X.
