Don't worry about criticisms...I'm fully confident that if you tried the product all criticism would go right out the window :D

Pose Magic is a non-rendering PP2.  You load the prop, it attaches itself to your figure, then you inject the pose magic code into the figure.  There would be no way to have it auto-load, except for this...don't you tend to get your figure ready and save it as a pz2 you use to open poser directly?  That's how I work, at least...I've got my favorite character saved at a baseline with all my preferred settings and options etc and use that Pz3 to load poser.  In this scenario, you would already have PoseMagic loaded whenever you open your pz3.

Since it is a prop (so to speak) you would still be using the parameter panel.

Since it is a prop and a pose it should work on a Mac, as long as that mac is running Poser 8 or Poser Pro 2010.

There is a python script included that turns PoseMagic settings into regular pz2 files.

I will check the archives and see if previous PoseMagic editions have worked on a mac (I honestly can't remember)
