Q. Why won't my EndNote work anymore on a Mac running the Catalina OS?

EndNote & Mac Catalina OS

The current version of EndNote (X9.2) will not work with the new Catalina operating system for Mac.

EndNote have released a new update version (X9.3.1) for Macs to fix this problem. This version also works on older Mac operating systems.

If you have not yet upgraded to Catalina:

• A pop-up notification of the update will appear when you open EndNote.
• Close all Microsoft Office programs
• Click the Download and Install button to run the update.

If you have already upgraded to Catalina you will need to reinstall the software:

• Go to the EndNote guide > select Download EndNote
• Login and go to the Download section
• Agree to the conditions of use and choose Macintosh from the drop down menu
• Choose the version X9 from the drop down menu and click Download. This will download the new version of the software
• Once downloaded, install the program as usual.

File conversion

• Due to the change in database format, existing libraries will require conversion when first opened in X9.3.1.
• This will create a new, converted version of the library for use with X9.3.1, but will not alter the original file.
• The original file will still be able to open in X9.2 and earlier but will not contain any changes made in the newer version unless synced online.

Cross Compatibility

• EndNote X9.3.1 Mac libraries are currently not cross-platform compatible with EndNote for Windows.
• If you use your EndNote library across Mac and Windows computers you will need to use the online sync function to keep your library current on both machines.
• The X9.3.1 patch for EndNote (Windows) will be available later this year to restore cross-platform compatibility.
