Are you facing the following problems with iTunes on Mac OS X Mavericks (10.9.1)
- Books is missing under the Library section on iTunes App.
- Any PDF’s added via File -> Add to Library in iTunes is not available for device sync.
This means that you will not be able to sync any newly added PDF books to your iPad or iPhone. One possible solution to resolve the above issues is use iBooks on Mac. It is strange but you need to add PDF’s and other file formats related with Book to iBook App. Launching iBooks should copy all the existing Books from iTunes to iBooks.
Now to add new PDF files, click File menu and select Add to Library.
Now navigate back to iTunes then to your device. Books section should show the newly added PDF’s and it is available for Sync with your device.
