im running on PC and it is one of the worst running aps i've ever had. its been on three comps and wont work smooth on any of them it locks up it locks you out of it. it gets fickele as ot what files it runs it has been reinstalled weekly even dailey it hates PhillC's MMonroe file(maby those refs to files and texs placed in drives or dir on his which arent there on mine have something to do with that) i have a utility dir that is two screens long and well used. with poserloader and p3do pluss cr2edit being used to get the pieces straight to run for a day or two allover itr seems worth it's trouble except fot that tatoo of the s.n. on my hand from righting it there so mutch when it works i like what it dose
