Probably. How else would Psystar (a company that's claimed to the courts that they don't have any accounts or even bank statements to disclose!) get the expensive lawyers they have. But who pays the lawyers fee is conveniently a matter of client confidentiality. Most likely a Chinese PC maker with no high margin business alongside its PC hardware offering.
@Iam Me: Not likely to be bankrolled by MS. Why would MS want competition for OEM OS supply? And no, they couldn't buy Apple several times over. Apple even has more cash than MS, and none of that funky nonexistent "goodwill" stuff so prominent in the balance sheets of MS, HP etc.
@Jimmy Floyd: Sorry to hear about Apple forcing hardware on you. How does that work exactly?
Apple doesn't actually hinder hackintosh activity if its not for commercial gain, although it is deprecated, and outside the license terms. Be grateful there's no serialisation, compulsory registration, or product activation for OSX. Much greater benefits if you want to "try" OSX on your standard PC hardware than Microsoft's Windows Product Activation if you want to "try" Vista. So, Apple haters, be careful what you wish for when you say OSX should be legally installable on your PC.
The real issue Apple is defending here is not the existence of tinpot cottage industries turning out Mac clones round the world, it's ensuring the big players can't bundle OSX on their HP's, Dells, Acers etc.
