  def caveats; <<-EOS.undent
    On some Macs, the graphics drivers do not properly support stereo
    graphics. This will cause visual glitches and shaking that stay
    visible until X11 is completely closed. This may even require
    restarting your computer. Launch explicitly in Mono mode using:
      pymol -M
    EOS
