In Apple Inc. v. Psystar, a California District Court granted Apple's motion for summary judgment for copyright infringement against Mac clone manufacturer Psystar, finding that Psystar had violated Apple's reproduction right, distribution right and right to create a derivative work in its Mac OS X operating system. It also dismissed Psystar's cross-motion.

Psystar developed and sold clones of Apple's Macintosh brand of computers with a modified version of Mac OS X. Psystar bought a copy of the Mac OS X and installed it on a Mac mini. It then copied the OS onto a non-Mac computer which became the imaging station. Psystar removed and replaced the Mac OS X bootloader as well as the OS X kernel extension files. The kernel extensions were responsible for locating the hardware decryption keys.
