It's uncertain if the software will be released for Mac because there is nothing about it on the developer's website. Either the development has been discontinued or the software has been replaced with another application from their portfolio. Since I couldn't find anything about the software, I recommend checking their available products and eventually get in touch with them through the available channels.
