But those who are using macOS Catalina or above are not allowed to use MongoDB default data directory of /data/db because Apple restricted access so, you need to create a different data directory and you are allowed to keep that directory wherever you want in your system.

I had to reconfigure my Macbook after sending it for repairs. During the reconfiguration period, I noticed the instructions I linked to in “Setting up a local MongoDB connection” were outdated.

Here’s an updated version on how to install MongoDB on a Mac.

  1. Installing MongoDB on Mac (Catalina and non-Catalina) 14th Feb 2020. I had to reconfigure my Macbook after sending it for repairs. During the reconfiguration period, I noticed the instructions I linked to in “Setting up a local MongoDB connection” were outdated. Here’s an updated version on how to install MongoDB on a Mac. There are a few.
  2. # install homebrew (and run the following commands sudo chown -R $(whoami) $(brew -prefix)/. brew tap mongodb/brew brew install mongodb-community@4.2 ## - aliases to set in your zshrc file # open your zshrc file open /.zshrc # copy and paste shorcuts in the end of the file alias mongod='brew services run mongodb-community.

There are a few steps:

Catalina

First, you install Homebrew. If you’re curious about what Homebrew is, read this article.

Second, find the MongoDB tap.

Third, install MongoDB.

MongoDB is now installed on your computer.

Preparations (Before MacOS Catalina)

Before you can use MongoDB, you need to create a /data/db folder on your computer to use MongoDB. You can create this folder with the following command:

You also need to give permissions to use it:

Now you can follow the rest of the article to set up your MongoDB connection.

Preparations (MacOS Catalina onwards)

Install Mongodb In Mac Catalina

Apple created a new Volume in Catalina for security purposes. If you’re on Catalina, you need to create the /data/db folder in System/Volumes/Data.

Use this command:

Then, use this command to give permissions:

Using MongoDB

In the past, I can run the mongod command to start MongoDB. This no longer works out for the box from MongoDB v4.2.3 onwards.

The best way to start MongoDB now is via brew services.

Starting MongoDB

Use this command:

MongoDB will start as a background service. Here’s what you’ll see:

You can use start instead of run. start will start MongoDB automatically when you login into your Macbook. I prefer run since I don’t want MongoDB to be running all the time.

Checking if MongoDB is running

Use this command:

Homebrew will list all running services. If MongoDB is running, mongodb-community will have a status set to started.

The Mongo Shell

If MongoDB is running, you should be able to access the Mongo shell with the mongo command.

Stopping MongoDB

Use this command:

Homebrew will stop MongoDB and let you know.

Aliases to make these easier

It’s a chore typing brew services run mongodb-community every time I want to start MongoDB.

I created some aliases to make things easier for me. Here are my aliases:

In this tutorial I am going to talk about how you can install MongoDB on MacOS in an easy way. I have gone through many tutorials online, but I have been really upset with those tutorials. Most of the tutorials are outdated and old. So I decided to create this tutorial in which i can show you a better and easy way to setup MongoDB on MacOS.

Install MongoDB on MacOS using Homebrew

In order to install MongoDB on MacOs, I would suggest using Homebrew.

Please open up the MacOs command line tool and paste the following command to setup MongoDB on MacOS.

Install mongodb osx catalina

Install Mongodb Osx Catalina

Install mongodb in mac catalina os

Install Mongodb In Mac Catalina Operating System

Once you entered the given above command, your MacOS terminal will start some process. Those processes are nothing but related to creating some folder in your local machine where all the Homebrew related settings are kept.

After finishing the installation process, check your Homebrew dependencies.

Hit the below commands to install MongoDB

After MongoDB successfully installed in your machine, then create a folder to store MongoDB data using given below command

Use the given below command to assign the proper permission to MongoDB data folder.

We’ve successfully installed the MongoDB on MacOS also assigned the proper permission. Now it’s time to run mongo daemon service. This service makes the connection and performs the task in the background. Hit the following command to run MongoDB.

Now your apps are all set to communicate with MongoDB. Mongo is correctly working in the background with the help of mongo daemon. You might also check which MongoDB version you are working on, just hit the below command in the terminal.

mongo --version output

Above command will tell you which MongoDB version is running in your local machine. Using the latest version has always been a good practice. It protects you from compatibility chaos with client-side app.

However, if you are using latest Mac version Catalina then the root folder is no longer writable.

Brew has an updated version of mongodb to use a new path (which it creates itself), /usr/local/var/mongodb and following these instructions will fix the issue:
