MongoDB Atlas is a hosted MongoDB service option in the cloud which requires no installation overhead and offers a free tier to get started.
Use this tutorial to install MongoDB 4.4 Community Edition on macOS using the third-party Homebrew package manager.
This tutorial installs MongoDB 4.4 Community Edition. To install a different version of MongoDB Community, use the version drop-down menu in the upper-left corner of this page to select the documentation for that version.
MongoDB 4.4 Community Edition supports macOS 10.13 or later.
See Platform Support Notes for more information.
Before deploying MongoDB in a production environment, consider the Production Notes document which offers performance considerations and configuration recommendations for production MongoDB deployments.
Ensure your system meets each of the following prerequisites. You only need to perform each prerequisite step once on your system. If you have already performed the prerequisite steps as part of an earlier MongoDB installation using Homebrew, you can skip to the installation procedure.
Homebrew requires the Xcode command-line tools from Apple's Xcode.
Install the Xcode command-line tools by running the following command in your macOS Terminal:
macOS does not include the Homebrew
brew package by default.
brewusing the official Homebrew installation instructions.
Follow these steps to install MongoDB Community Edition using Homebrew's
brew package manager. Be sure that you have followed the
installation prerequisites above before proceeding.
Tap the MongoDB Homebrew Tap to download the official Homebrew formula for MongoDB and the Database Tools, by running the following command in your macOS Terminal:
brew tap mongodb/brew
If you have already done this for a previous installation of MongoDB, you can skip this step.
To update Homebrew and all existing formulae:
To install MongoDB, run the following command in your macOS Terminal application:
brew install firstname.lastname@example.org
Alternatively, you can specify a previous version of MongoDB if desired. You can also maintain multiple versions of MongoDB side by side in this manner.
If you have previously installed an older version of the formula, you may encounter a ChecksumMismatchError. To resolve, see Troubleshooting ChecksumMismatchError.
The installation includes the following binaries:
In addition, the installation creates the following files and directories at the location specified below, depending on your Apple hardware:
See Apple's documentation
for the current list of Apple hardware using the M1 processor. You can
also run the following command to check where
brew has installed
these files and directories:
Follow these steps to run MongoDB Community Edition. These instructions assume that you are using the default settings.
You can run MongoDB as a macOS service using
brew, or you can run
MongoDB manually as a background process. It is recommended to run
MongoDB as a macOS service, as doing so sets the correct system
ulimit values automatically (see
ulimit settings for more information).
To run MongoDB (i.e. the
mongodprocess) as a macOS service, issue the following:
brew services start email@example.com
To stop a
mongodrunning as a macOS service, use the following command as needed:
brew services stop firstname.lastname@example.org
To run MongoDB (i.e. the
mongodprocess) manually as a background process, issue the following:
For macOS running Intel processors:
mongod --config /usr/local/etc/mongod.conf --fork
For macOS running on Apple M1 processors:
mongod --config /opt/homebrew/etc/mongod.conf --fork
Both methods use the
mongod.conf file created
during the install. You can add your own MongoDB
configuration options to
this file as well.
macOS Prevents mongod From Opening
macOS may prevent
mongod from running after installation. If
you receive a security error when starting
indicating that the developer could not be identified or verified,
do the following to grant
mongod access to run:
Open System Preferences
Select the Security and Privacy pane.
Under the General tab, click the button to the right of the message about
mongod, labelled either Open Anyway or Allow Anyway depending on your version of macOS.
To verify that MongoDB is running, perform one of the following:
If you started MongoDB as a macOS service:
brew services list
You should see the service
If you started MongoDB manually as a background process:
ps aux | grep -v grep | grep mongod
You should see your
mongodprocess in the output.
You can also view the log file to see the current status of your
To begin using MongoDB, connect a
mongo shell to the
running instance. From a new terminal, issue the following:

Starting in MongoDB 4.4.1, installing MongoDB via
brew also installs
the MongoDB Database Tools.
The MongoDB Database Tools are a collection of
command-line utilities for working with a MongoDB deployment,
including data backup and import/export tools like
mongodump as well as monitoring
Once you have installed the MongoDB Server in the steps above, the
Database Tools are available directly from the command line in your
macOS Terminal application. For example you could run
against your running MongoDB instance by invoking it in your
macOS Terminal like so:
It should start up, connect to your running
mongod, and start
reporting usage statistics.
See the MongoDB Database Tools Documentation for usage information for each of the Database Tools.
By default, MongoDB launches with
bindIp set to
127.0.0.1, which binds to the localhost network interface. This
means that the
mongod can only accept connections from
clients that are running on the same machine. Remote clients will not be
able to connect to the
mongod, and the
not be able to initialize a replica set unless this value is set
to a valid network interface which is accessible from the remote clients.
This value can be configured either:
If you have previously installed an older version of the formula,
you may encounter a
ChecksumMismatchError resembling the following:
