EndNote X9 for macOS Customers
EndNote X9 for macOS has been updated for compatibility with Catalina. If you already have EndNote X9, please install all updates as they become available to avoid interruption in your workflow. You can access the updates here.
However, if you have already upgraded to Catalina OS before updating your EndNote program to EndNote X9.3.1, the EndNote app will be disabled in the Applications folder. To fix this, you would need to reinstall the EndNote X9 version with the latest update (EndNote X9.3.1).
You can download the EndNote X9.3.1 updated installer file from here
Once downloaded, double click the installer file to proceed with installation. During installation, click OK when asked to overwrite the existing application.
For Single User Licenses: You will need to enter the EndNote X9 Product Key to complete the installation.
Note: If you are part of a site license, please check your university or company web site to update to EndNote X9.3.1.
EndNote X8 and earlier for macOS Users
Since Apple has made the decision to drop all 32-bit application support, we expect that macOS 10.15 Catalina will not run EndNote X8 and earlier. However, we want to continue to support you. We recommend contacting Product Support or Sales for details.

- If you’d prefer not to upgrade to EndNote X9, you may keep working on your current macOS. We do not recommend upgrading to Catalina with EndNote X8 and earlier as we expect major compatibility issues.
If I don’t have EndNote X9, can I keep using my existing version?
Yes, you may continue using your older version of EndNote with macOS Mojave or earlier. However, if you upgrade to macOS Catalina, your older version of EndNote is not going to work.
If I have EndNote X9, how will I know if it’s ok to upgrade to macOS Catalina?
EndNote X9 for macOS has been updated for compatibility with Catalina. The new version will be called EndNote X9.3.1. Once you have installed X9.3.1 you can upgrade to macOS Catalina.
To check what version of EndNote X9 you have installed, please launch EndNote and then click on the EndNote menu on the top right. A Catalina-ready version of EndNote will read “About EndNote X9.3.1” If X9.2 or any other version of EndNote is listed here, it will not be compatible with Catalina.
In addition, macOS Catalina will warn you during installation about applications that are not compatible with their new restrictions. If EndNote is listed here, it will not work. We recommend cancelling the installation at that point and rolling back to your previous operating system.
