This is false. Apple's first multiprocesser G4 systems were released
nearly two years ago. Many years before that there were multiproc
PowerMac clones using PPC 604 chips.
 
Until OS X, mac systems could only handle Asymmetric Multiprocessing,
which was less efficient than the Symmetric MP that OS X and the newer
Windows systems offer, but still allowed significant speed
improvements under MP-aware applications such as Photoshop. (Only
certain operations under Photoshop benefit from multiprocessing.)
