> There's no Altivec in the G4 processor that drives the mac mini. According to Apple, the mini's do have a "Velocity Engine" aka Altivec. However, PyMOL doesn't itself use it, though we seriously considering writing some Ativec code for MacPyMOL back when the G5 came out. With Apple now going to Intel chips, I'm glad now that we didn't waste our time on that.
