Apple has been successful in shutting down two websites that report on efforts to make Mac OS X run on non-Apple computers. The company cited violations of the US Digital Millennium Copyright Act (DMCA). Seemingly, the sites featured details on how to hack the Intel-compatible version of Apple's operating system, to get Mac OS X to run on unsanctioned hardware.

Under a controversial clause of the DMCA it is illegal to circumvent or provide information about how to circumvent digital rights management technology designed to prevent the unauthorised use of copyright-protected material.
The maintainers of the websites claimed that they would be working with Apple to ensure that they complied properly with the company’s wishes.
