I have a Mac computer and so far I only found this download for Windows. Is there a link for Mac?
No, there is no link for Mac operating system. I have checked and the only thing you can download is the version for Windows OS. There is nothing available in terms of compatibility or system requirements.
However, you can try Wine Bottler to run the application on Mac. Wine Bottler makes it easy to load Windows apps on Mac.
