What are the system requirements, beyond Mac OS X ?
The requirement is a credit card with a U.S. address, Mac OS X 10.2.5 or later, a connection to the Internet (broadband recommended), 256MB RAM (recommended), and iTunes 4 or later (a free download from Appleās website). Quicktime 6.2 (free download) is required to fully exploit the AAC capabilities of iTunes 4. Apple intends to expand iTMS to Microsoft Windows clients later this year, and is working toward opening the service to the rest of North America and the world at some unspecified point in the future. The latter intention is dependent on music industry cooperation, since the copyright laws are different in other countries than the U.S. From the main iTunes Music Store menu, you can click on “Requests & Feedback” and submit either (but not both at the same time).
