Maybe someone can help me. I'm trying to download firmware updates for the Panasonic 35-100. I have the downloads on my Mac Mini (10.7.5) but the files won't open when I click them. My mac says I need an App. Can I just drag the files to my memory card and proceed? The panasonic site says I should open them 1st and that my OS should do it. Any help would be much appreciated!!
