"so you mean that I must apply each option to -say V3 (apply each eye color choice to her head) and then save...?" No, don't do that because MAT poses aren't re-saveable. Poser will overwrite the useful stuff with the figure pose, which isn't what you want. Although I think Poser 6 has ways of doing this, your best bet is to contact the merchant and ask searching questions. Did they actually have it tested by a Mac user? If it ought to work, it ought to be fixable.
