Once installed, you will want to check that you are using EndNote X9.2 using the steps above.

To install EndNote X9, click on the Download for Mac button. If you are using an older version of EndNote (such as EndNote X8 or earlier) you will need to install EndNote X9. With Endnote open, click Endnote X9 menu button.If you are using EndNote X9 but not EndNote X9.2, please update. To fix this, you will need to reinstall the EndNote X9 version with the latest update (EndNote X9.3.1) (click on the Download for Mac button). If you have already upgraded to Catalina or Big Sur before updating your EndNote program to EndNote X9.3.1, the EndNote app will be disabled in the Applications folder. Please note that when you open an existing library in X9.3 and later for Mac, it will create a converted version for use with this new database engine. Quit EndNote and run the downloaded file.Download the EndNote X9.3 update here: EndNote X9.3.1 Update Installer.zip.The first line should say About EndNote X9.2.Click on EndNote X9 menu on the top left of the page.Make sure you have EndNote X9.2 already installed.Ideally, you should manually install the update BEFORE you update to Catalina or Big Sur. EndNote has released an update to solve this problem. These new operating systems are incompatible with older versions of EndNote. Apple has released two new operating systems, Catalina and Big Sur.
