Step 3:


n the Finder, to Go->Utilities, then find the Terminal application (or do a Spotlight search for “Terminal”) and start it.
In the new Terminal window (the “prompt”), type java -jar (note trailing space after “-jar”).
Drag the epubcheck .jar file from the unzipped folder in the Finder into the Terminal window (the location of the file [“path”] should be copied).
Type another space in the terminal window after the .jar filename.
Similarly, drag the EPUB file from wherever in the Finder into the Terminal window (it’s path should also be copied).
Press Return.
Note the results in the Terminal window (No errors or warnings detected means it passed).
