I'm working on a pc so I can only assume the situations are the same. Essentially with the standard P5 and Vue4 updates you can only load a single frame at a time. With Mover you can load an animation from the Poser file. I can't vouch for the compatabiliy of P5 hair and cloth in just a single frame without the Mover plugin as I do have Mover but P5 dynamic animations does indeed work on the pc with the latest updates for P5, V4 and Mover.
