Uninstall CouchDB Completely Mac OSX

I've played around with my couchdb configuration and I would like to start fresh again, remove the app and downloading a new one didn't seem to remove the configuration completely, where I still have to access with my username and password, and my dbs are still there.

Looking around on internet, I don't seem to find a solution to fix the issue on mac os x (mavericks)

Well, I've done some things like:

• removing the cache folder from ~/Library/Caches
• removing any related file/folder in ~/Library/Application Support/CouchDB
• checking the config file from ~/Library/Preferences/couchdb-server.ini seems to be an alias to config file in Application Support CouchDB folder
• I also removed a couple of files that I don't remember their names

Still installing a fresh download couchdb is not working application and now I am getting the json message: {"error":"unauthorized","reason":"Name or password is incorrect."}

P.S: My System is Mac OS X Mavericks and Couchdb 1.5.1

Well, it seems I've found the missing file very soon, after I posted my question, so for anyone who gets this problem in future, this is the culprit file:

/Users/kouiti/Library/Preferences/org.apache.couchdb.plist
