If I could give this -1000 stars I would.

This app simply does not work for a MAC. I have it on my old PC and it sort of works ok - it misses chapters sometimes. However on my Mac, I can never get past the login/server error. I have tried this many times and made new login and it is worthless. I am just happy one of my local libraries uses overdrive and works just fine on my Mac.
