Apple encountered its one and only setback in its court victory over Psystar Tuesday after Judge William Alsup ruled that it couldn't keep secret details about how Mac OS X worked. Apple couldn't order sealed documents about the boot-up checks to verify Mac OS X, its integrity checks, and its heat sensor management. Apple tried to argue that information it hadn't confirmed itself still had to be secret to avoid , but Alsup countered that trade secret laws couldn't be used simply to avoid confirmation of details already available in books and published code.
