imageThey’re baaaack. Mac cloner Psystar has been granted an extension for filing an opening brief in its appeal against Apple. The company now has until May 17th, 2010 to file said brief, and Apple’s reply will be due on June 16th, “World of Apple” ( reports.

In January Psystar officially filed its Notice of Appeal in the copyright suit it lost against Apple. The appeal involved a copyright infringement suit Apple brought against Psystar to stop the Florida company from selling Psystar computers with Mac OS X installed.

In December 2009 Apple won as permanent injunction against Psystar. Granted by Judge William Alsup of the US District Court for the Northern District of California, it prevents the Mac cloner from selling clones, installing Mac OS X on any hardware, and selling or copying Mac OS X.

Psystar also can’t manufacture, import, offer to the public, provide or otherwise traffic in any technology, product, service, device, component, “or part thereof that is primarily designed or produced for the purpose of circumventing a technological measure.As for Rebel EFI, the judge while expressing that Psystar was not very clear about what it does, refused to exclude it from the injunction, and says Psystar continues to sell it “at its peril” at the risk of “finding itself in contempt if its new venture falls within the scope of the injunction.”
