Ok, so i recently upgraded to a 1TB hard drive in my macbook, and moved all of my music/ebooks over to new locations (local, rather than on my NAS drive), and when i go to sync my books on my iPad, in the sync ebooks tab, they are ALL checked. I dont want to sync ALL of my books. I also dont want to go through and uncheck hundreds of books one by one. How can I uncheck all without clicking each one manually?
