If Python works in Poser on the Mac, it should work. But python is only available in the ProPack and Poser 5. I'll chime in and say that his LightPanel is, for P5, one of the coolest tools ever -- not only can you delete all the lights, you can chose to delete only some, change them around from ray trace to shadow map, change colors, type -- basically, one panel that can change all your light settings in one nice and easy place. On the link above, you'll see his delete lights script close to the top, but the panel is a bit of the way down. And every one of these scripts is just the coolest little things. COuldn't do stuff without him :)
