Starting neo4j on mac

I'm trying to, unsuccessfully, start the neo4j server. I've followed the guide, http://docs.neo4j.org/chunked/snapshot/server-installation.html#_mac_osx_service, but keep getting the following error:

Starting Neo4j Server...WARNING: not changing user
 process 开发者_运维问答[22112]... waiting for server to be ready......................................................................................................................... BAD.

Any ideas?

I was attempting to open multiple instances. Simple grep showed that the process was already running.

For reference some commands:

./bin/neo4j start 
./bin/neo4j restart
./bin/neo4j stop 
./bin/neo4j info

I closed down my node servers and it fixed this problem.
