Ok...
Today when I connect the Boox to my MacBook via usb cable, it does work
- it asks whether I want to connect to PC or not...
But I don't think I am doing anything differently...
Anyway! I'm happy!
Now, I'm gonna try the SD card again. Fingers crossed...
Funny... that was the card - I say funny, because we use it for our photo camera and it works fine...
Anyway... Case closed
