i can't add pdfs to ibooks
I have a mac pro , using a network cable to attach to my macbook pro. I am moving my pdfs over to ibooks. All has been fine but suddenly i get this message 'couldn’t be moved to “Books” because either the former doesn't exist, or the folder containing the latter doesn't exist' ? I have added a hundred already with no issue whatsoever but suddenly this ?
Tried moving the pdfs to the local drive then adding but same ? This is really bizarre as it was working and suddenly not with nothing changed
Mac Pro, OS X Yosemite (10.10.3)
