To answer your question: YES an NO! It is partly possible. Cause my program uses ADB the transfer would work. But the whole suveillance of the folder (managing the transfer of new files) is written in a language (autoit) that isn't compatible with mac. Currently there exist some "ports" to transfer a program to mac-code but they don't work.
But I think I can help you.
There are three ways:
1.
If you have some experience in programming I can give you a commented version of the program code and you can translate it by yourself into Mac-code.
2.
I could write the program in C, C++ or Java and try to get it running on Macs. But this would take some time cause I don't have many experience with Mac and have to do some other stuff too.
3.
You could try to run the program in some kind of emulator (don't know if there is one that works) and hopefully connect it to Calibre.
The third way would be the fastest but probably not manageable one. The second way takes at least 3 months and the first is only possible if you are a programmer.
In future I would like to port the whole program to C or Java, cause the liability of this program-languages is much higher. But this will take very long. (Currently I have not so many time. Still have to do something for school)
I hope you are able to find a way that suits your expectations.
