Hopefully you’ve found the answer to your question.
For future Forum searchers, I’ve found on the Mac’s one has to map the shared drive first (e.g., Finder>Go>Connect to Server, or Apple Key+k). Then in Klok you would need to enter the information as:
Mode = Network File Mode
Network Path = /Volumes/Klok (or whatever you named the share)
Then follow the install instructions to complete.
