Most of the time it should be OK. I'm on a Mac and I've purchased a few items labeled as "PC Only." I bought one item from BAT Labs' store and it worked fine. One of Richabri's building packs did require me to edit the cr2 file and shorten the name of the obj that it referenced. The path name was too long apparently and certain items wouldn't load. Once I got that fixed however, things seemed to work fine. I have that problem with the occassional d/l from Poserworld as well. Sometimes a product is labeled "PC Only" because the merchant doesn't have the ability to test on a Mac and probably doesn't want to deal with pissed off customers screaming about problems. Anyway the short answer based on my experience so far is: Most figures should work. No guarantees though.
