Thanks for your answer Allstar12345!
But alas, I am too inexperienced to use Virtual Box from the Terminal. If someone showed me how to do it, maybe I'd be able to on my own as well... I'm using "wine", which is also a kind of Windows-emulator. "Phoenix" fails to work on there. But I get "J.A.F" to run. It just cannot connect to my phone. And that is due to the fact that the USB-drivers in "wine" aren't exactly compatible with Mac OS, I think. Anyway, it was worth a try!
All the best!
