I ran it on a MacBook Pro Retina running Mavericks 10.9.1 with no troubles. Recovered video files as well as JPG pictures. Over 209 files in total recovered. Some new photos had been taken on the card after he deleted the others (assuming he formatted the card, but I'm not sure, may have just done a delete all on the camera).
So you can add the Panasonic DMC-ZS30 to the list of compatible cameras on your page

The file format I selected was the Fat 16/32 etc option.
Thank you.
