Hi everyone, thanks for your help. The EPubZip does the trick!
Here is what I had to do for anyone else interested.
--Install the ePub Zip app.
--Launch iBooks.
--Drag the iBook icon (from inside iBooks) on top of the ePub Zip app.
Note: you do not double click the ePub Zip app to launch it, you just drag the icon onto the app file. Also, you are not dragging the epub file from the finder folder, you are dragging the actual icon of the book from inside iBooks.
If you cannot install ePub Zip because of security, then do the following: Apple, System Preferences, Security & Privacy, General tab, select to allow from this developer.
Here is the link to the ePubZip again:
