I've been testing sextante plugin on Mac with much pleasure and relative success. Some ftools modules work (centroids, line to polygons, polygons to line, voronoi polygons) as expected where other produce not visible results (e.g. basic statics or nna, that pop up a new window but with anything visible in there), but others complaint about python (e.g. sextante help, or line intersections). I can provide a more complete report if needed. As far as I can't red the instructions under sextante help, maybe my settings are wrong.<div>
Tested in both 1.7.4 and 1.9alpha<br><div>
