Hey!
I've sent you the two first objects you asked for on your profile activities. I don't think everybody would be happy about sharing the game files so you should remove it after downloading.
I don't know anything about OSX computers, but isn't there a way to emulate Windows environment and use S4S for Windows somehow? I can't really help you with that, but if you want objects then that might make it easier than asking for them. At least you're just doing poses and you don't need to turn them back into the package.
Good Luck with the poses!
