I have installed dataloader version 48 in my mac, I too have installed Zulu Java Sdk. I am trying to export Account object data from the sandbox and so far I am able to login using Password Authentication. However, when after successful login when the list of objects appears and I choose Account or any other object, my dataloader stucks there and in terminal it shows below-mentioned error.

INFO  [main] dao.DataAccessObjectFactory getDaoInstance (DataAccessObjectFactory.java:51) - Instantiating data access object: extract.csv of type: csvWrite
java.lang.NullPointerException

Really,not sure the reason behind it

When you choose Browse, to select the Target for Extraction, and you choose a proper directory, does that help? When I launched this on my mac, choosing "Browse" immediately suggested I save the file to my Downloads folder. Could folder access be the issue?
