King, I have my ipad hooked up to my macbook air (Mavericks). I am trying to transfer over 100 pdf's on my ipad to my mac with no luck.
I did this, "Mac's iTunes via File > Devices > Transfer Purchases" and they still aren't showing up in my ibooks.
These pdf's aren't showing up in itunes, within my ipad device under books, only a couple I downloaded form the itunes store???
Do the PDFs still show in the iBooks app on your iPad ?
If I select the 'Books' on my iPad 'device' on the left-hand sidebar of my Mac's iTunes then all the PDFs, as well as ibooks, that I have in the iBooks app on it show there.
And in the iBooks app on your Mac you are viewing the 'All Books' tab and have tried the File > Move Books From iTunes ?
