Just did a quick check, TC2 not for Mac. So much for that idea. As for using A3 on V3 the texture maps are the same but A3 has two material zones for the legs where V3 only has one. This means that if you try to apply a mat pose from A3 to V3 the legs will not have the texture applied. Just go to the material room, copy the Image Map node from SkinTorso to SkinLeg and you should be good to go. Hope this helps.
