I am trying to delete the facebook & twitter apps I have on my imac I downloaded from the app store. I have moved the icons to trash and then emptied trash. However the icons are still present in my app folder. It was suggested to me that I check to make sure permissions are set at read and write. I do that and it automatically reverts back to read only for everyone but the admin which is me. Ive tried repairing permissions and that doesn't work either. I'm running Lion if that helps. Does anyone know anything else I can try. Any advice is appreciated
