not entirely sure, as I am a windows user… sorry – but I found this in the knowledgebase:
Note: If you’ve saved your EndNote library as a package file (.enlp extension), you’ll need to extract the package library’s internal .enl file and Data folder before recovering:
- Quit EndNote.
- Use Finder to navigate to the folder where your .enlp library file exists.
- Hold down the “control” key on your keyboard while clicking the package library file. Choose “Show Package Contents” from the resulting menu.
- Now that you’re looking at the contents of your package library, drag and drop the .enl file and .Data folder from this Finder window and place the two library components elsewhere, such as your Desktop.
- Proceed with the library recovery process as listed above by selecting the .enl file that you dragged out of the package library.
