Oh your hypothesis is correct. I ran fdbcli and ran the status command which outputted:
Could not communicate with a quorum of coordination servers:
127.0.0.1:4000 (unreachable)
After doing some more searching, according to this post, I should start up the server by running ./bin/fdbserver. However, it seems like I do not have fdbserver at that location. Is there someplace I should go to install this or is it possible that it is located in a different path? The confusing thing to me is that I already installed the FoundationDB Client & Server Package for macOS which I assume should install fdbserver for me?
