Catalina does not support the version of EndNote currently available from ITAC. You will need to update your Endnote software to 9.3.1 prior to upgrading your OS to Catalina. EndNote 9.3.1 will be available for download around the middle of November.
NOTE: EndNote cannot export citation information directly from the Westlaw Academic or Nexis Uni databases. References from these databases must be entered into EndNote manually.
Please Ask a Librarian for assistance.
