The issue is with a couple of hair props and their MATs not applying properly. It may be a Win/Mac problem, I don't know. But I think potential buyers should be aware that all is not smooth sailing, at least for Mac users. I actually did contact the vendor, and he/she gave me a list of what tex/trans to apply where, manually, but frankly it's a pain in the ass--the props keep making you find texture after texture every time you load them, which is time-consuming and annoying, and makes the items more trouble than they're worth-- especially given all the great free hair that's available these days. Some items I've bought in the marketplace have worked perfectly, some have needed tweaking (actually had to edit the obj files for a couple of Billy-T's things), and some have been real disappointments. I think that information should be available to other potential buyers--otherwise "customer feedback" should be called "testimonials" or "happy campers" or something.
