On Thursday, Apple released the latest version of QuickTime, its multimedia support system for Mac OS X and Windows. The new version, known as QuickTime 7.6.4, is available as a variably-sized download (depending on version chosen through the download page), improves compatibility with iTunes 9 and improves audio device support on Windows Vista.
The update requires Mac OS X 10.4 or later to install and run and can be located and snagged via Mac OS X’s built-in Software Update feature.
