Psystar copies the hard drive of a Macintosh computer containing Mac OS X (as depicted above on the left side of the diagram) onto its "imaging station" computer (shown in the middle of the diagram). This is the first unlawful copy.
Psystar then modifies this copy of Mac OS X to create a "master copy" that wil run on non-Apple computers. Psystar next uses "hard drive imaging" to install copies of its "master copy" of Mac OS X from the imaging station onto each computer it assembles. This is the second unlawful copy (a process repeated many times).
Finally, every time Psystar turns on any of the Psystar computers running Mac OS X, which it does before shipping each computer, Psystar necessarily makes a separate modified copy of Mac OS X in Random Access Memory, or "RAM." This is the third unlawful copy.
