zblur plugin for osX?

Are there anyone who could use zblur plugin for OSX?
Of cource I tried “Iris + Zbuffer”, I got only red screen.
Is there a new version of plugin?

I find DoF to be much easier to do in an image editing program - Photoshop for example. I’m on OS X as well, and don’t have a lot of luck with scripts.
