Exif Editor para Mac

I downloaded and paid for Exif Editor a couple of days ago. I wish you had a trial period, a “try before you buy” policy. Or, baring that, screen shots that show all the available fields and menus and the missing ones like print and export. That said, I’m impressed with the program: it’s well thought out and well designed. It looks great as well and will no doubt meet the needs of many people. But I’m looking for more camera information, like hyperfocal distance, and more flexibility in how I use the data. I need to be able to export the data to use in a spreadsheet so I can see the collected information from a group of photos. I will sometimes need to print. It was good to have taken a look at the program but if this was a trial period, I would not have bought it and I will not be using it. For those reasons, I’d like my charge refunded. I’m posting here because entries in messages section on the developer's website support page don’t go through but generate a 502 Bad Gateway response.
