I have been using story on my old windows laptop. I just got a new mac & can't manage to get epub (adobe) books onto the story. i am not great on computer but on pc it was easy as story showd up in adobe digital editions. On mac it just shows on desktop> I've tried clicking & dragging what I think is book across & it shows on story sometimes but when I try it, it just says "failed to open file"
All help gratefully received.
