I usually mark my own stuff as PC/Mac if I know that all the files can be used on a MAC. In the readme, I know you can unzip the critter to the Poser Directory and it'll all drop off where it is supposed to go. However, if I'm not sure, then I'll mark it PC Only until a MAC user can tell me differently. 'sides, neither MAC or Windows folks have a thing on us *ix guys for specialization requirements. (Had Poser running on Linux w/ WINE for awhile... it's full directory path was /usr/local/WINE/c/Poser4/ - and it still unzipped freebies properly. read PNG's like a mofo; just couldn't get it to read .rsr files for some odd reason. It ran about as stable as the San Andreas Fault on a bad day, though. :) /P
