I had this issue and followed all the instructions provided without any success. Upon investigating I found the issue with OSX is with the name of the file, when you download the file its "vericoin.conf.text" or "verium.config.text" while with windows you can just click on the file in rename it, in OSX its not that simple. The file needs to be renamed using the command line using the "MV" command. Sample command below.
#mv vericoin.config.txt vericoin.conf
This will ensure the file is renamed properly and will work once placed in the correct folder.
I hope this helps others.
