They may own the rights to the OS, but that shouldn't matter in this case. From what I know, PsyStar was simply buying legal, retail copies of the MacOS and installing them on their products. I see nothing wrong with this.
The doctrine of first sale should, in a good world, trump any of Apple's claims.
I never bought a copy of a Mac OS, but I would bet you dollars to donuts that the restrictions on the purchaser are spelled out in abundantly clear language.
I just nipped over to the Apple store web-page, and the Software License Agreement is right there, spelled out in black-and-white. It permits the purchaser to install the software on “Apple-labeled” computers. Seems pretty clear to me.

Maybe not. That software license they bought has stipulations you must agree to before using it. That said, I also think most software licenses are bogus as they are written because they inside the package, make claims they are not entitled, and restrict usage beyond what I would consider reasonable.
