i been using percolate with the "app" pd0.38 (not the latest one maybe, but still) for some weeks if percolate.pd_darwin is in the extras folder and you have "-lib percolate" in your .pdrc (in your home dir) that should be enough at least it is in my machine do you get any errors in the pd window? best
