Oh your hypothesis is correct. I ran `fdbcli` and ran the `status` command which outputted:

```auto
Could not communicate with a quorum of coordination servers:
  127.0.0.1:4000 (unreachable)

```

After doing some more searching, according to this [post](https://forums.foundationdb.org/t/how-to-create-a-foundation-db/1102), 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?
