Psystar is a company that makes, among other things, PCs with Apple's Mac OS pre-installed (otherwise known as a hackintosh), has filed for Chapter 11 bankruptcy protection.
This move coincides with ongoing legal action brought against it by Apple, which doesn't like Mac OS being installed on non-Apple systems.
While the case doesn't seem to have been specifically referred to as the reason for the filing (there's currently no information about this on the Psystar website), it's not inconceivable that Psystar is looking to protect itself from the damages award that would come from losing the Apple case.
Chapter 11 bankruptcy allows businesses to continue trading while protecting them from creditors. It could be that Psystar is hoping the case comes to a conclusion while the protection is in place and that Apple has to join the creditor queue to get its damages, if which it's likely to get a fraction.
Psystar appears to still be selling PCs with Mac OS installed.
