Mac clone-maker Psystar countersued Apple this week and charged it with violating antitrust law, PC Magazine reports. The battle centers on a provision in Apple’s end user agreement that prohibits non-Mac hardware from running its operating system. Psystar admits to selling computers with such hardware, and says they can be sold for hundreds of dollars cheaper than Apple's MacBook.
Apple sued Psystar 4 months ago on several charges including copyright infringement and breach of contract. Psystar's countersuit accuses Apple of anti-competitive behavior, keeping prices artificially high, and forcing OS X users to buy Apple hardware. Psystar is seeking damages and a court injunction to stop Apple's alleged anticompetitive behavior.
