I downloaded the trial version of X8, on to my Mac, and now this is a tab on Word. However, the online version will work better for me. If I uninstall X8, will this avoid any conflicts with the online version? I don’t want to install Cite While You Write until I can avoid conflicts. There is nothing in X8 that I need to keep.
You can just swap the EndNote X8 tools with the ones for EndNote online. Please see this article:
You may have to Quit and re-start Word to see the name of the tab in the Ribbon change.
