Your right about Maconvertor, this has to be the most used utility on my Mac. As for the "PC only" tags there is a lot of confusion amoungst everyone as to what is compatible and what is not, so to be safe they just tag it Mac only or PC only. A lot of us out there are fairly new to poser and are learning all the little things that more experienced users take for granted, a never ending process as more and more people discover Poser.
