How to find the Pages plugin to make it work with EndNote
A Pages Bundle should be located in the Cite While You Write Folder in your Applications / EndNote X9 folder.
If you have downloaded Pages '09 from the Mac App Store, and do not see the Pages Bundle in the Cite While You Write Folder, you will need to install the Pages EndNote Plug-in from the Apple website: https://support.apple.com/en-au/HT204395
