How to delete pdf files in iBooks on mac?
Accidently, I added hundreds of pdf files from my dropbox into iBooks.
I manually tried to delete pdf files, and I found that some of them were deleted, but the rest of them haven't been deleted.
I tried and tried, but failed.
I couldn't even open the pdf files at all.
I accessed the "library folder >>> ..... >>> ibooks" and deleted all the files their, but still the "ghost" pdf files are shown in iBooks.
Any idea?
Thanks!!
