2.4. Mac OS installation

This section describes how to install Neo4j on Mac OS.

2.4.1. Unix console application

  1. Download the latest release from Neo4j Download Center.

    Select the appropriate tar.gz distribution for your platform.

  2. Check that the SHA hash of the downloaded file is correct:

    1. To find the correct SHA hash, go to Neo4j Download Center and click on SHA-256 which will be located below your downloaded file.
    2. Using the appropriate commands for your platform, display the SHA-256 hash for the file that you downloaded.
    3. Ensure that the two are identical.
  3. Extract the contents of the archive, using tar -xf <filename>

    Refer to the top-level extracted directory as: NEO4J_HOME

  4. Change directory to: $NEO4J_HOME

    Run ./bin/neo4j console

  5. Stop the server by typing Ctrl-C in the console.

When Neo4j runs in console mode, logs are printed to the terminal.

2.4.2. Mac OS service

Use the standard Mac OS system tools to create a service based on the neo4j command.

2.4.3. Mac OS file descriptor limits

The limit of open file descriptors may have to be increased if a database has many indexes or if there are many connections to the database. The currently configured open file descriptor limitation on your Mac OS system can be inspected with the launchctl limit maxfiles command. The method for changing the limit may differ depending on the version of Mac OS. Consult the documentation for your operating system in order to find out the appropriate command.

If you raise the limit above 10240, then you must also add the following setting to your neo4j.conf file:

dbms.jvm.additional=-XX:-MaxFDLimit

Without this setting, the file descriptor limit for the JVM will not be increased beyond 10240. Note, however, that this only applies to Mac OS. On all other operating systems, you should always leave the MaxFDLimit JVM setting enabled.
