In April, we reported that a company called Psystar was offering the first Mac clone. Using off the shelf PC parts and a modified version of Mac OS X Leopard, Psystar promised a cheaper alternative to an Apple Mac.

Despite some initial concerns about their legitimacy, Psystar has delivered what they have advertised and later even offered software updates and server models.

Throughout, Apple has remained quiet about the company and many have expected that they would pursue legal action. AppleInsider reports that on July 3rd, Apple filed a formal complaint against the clone manufacturer. Apple's lawsuit is said to on the ground of copyright infringement.

The Mac maker filed a formal complaint in the U.S. District Court for the Northern District of California on July 3rd, just one day after Psystar began distributing a modified version of the Mac OS X 10.5.4 Leopard update to customers who had previously purchased one of its unauthorized Mac systems.
