Any library created or updated with EndNote for Windows can be used by EndNote X and later for the Macintosh. No conversion is necessary. However, make sure the name of the library includes the .enl extension (for example, Medicine.enl) and include the associated .DATA folder.
If you are on a network, copy the library from the PC to the Macintosh. Otherwise, use Windows Explorer to copy the library to a removable storage disk. Use your Macintosh to copy the library from the removable storage disk to the Macintosh. Make sure you also copy the DATA folder found in the same folder as the library.
Note: If you plan to send an EndNote library to another EndNote X or later user, there is an easy way to compress all of your library files and folders into a single file. See Saving a Compressed Copy of a Library.
Start the EndNote program on the Macintosh. If you see a dialog prompting you for a reference library file, select Cancel.
From the File menu, select Open Library. Navigate to the location of the library you want to open.
As long as the library has the ".ENL" extension, EndNote can display it. If the library does not have the ".ENL extension as part of the file name, EndNote will not recognize it.
Select the library and click Open.
Once the library has been opened in EndNote on a Macintosh, it maintains the EndNote Macintosh icon and can be opened just like any other library created by EndNote on the Macintosh.
