How to Set Up Your Free Local N8N Engine in Mac?

N8N is an open-source workflow automation tool that helps you connect different multiple applications together inside the workflows. This platform does not require you to write any code, it offers you a visual drag-and-drop interface, supporting more than 200 different application integrations. It can be called a one-stop solution for non-technical people to synthesize the whole digital world into one single place.

Each application connection/action is called a node, such as sending an email or updating data. Multiple nodes can be connected using actions, or tools, or being processed by AI Agents. N8n marketplace also offers others’ deployment-ready templates of how they use it in their business use cases.

Because it is an easy-to-use powerful workflow automation tool, enterprises can find no difficulty to optimize their marketing and operational processes without investing heavily in complex AI products.

N8n offers us two approaches to using it.

• We can use n8n at their website: https://n8n.io/ with a free trial duration of 14 days. After that, we can continue using it by purchasing their n8n cloud services. 
• Thanks to its open-source option, we can run it locally or host it ourselves and use all its features for free.

In the following sections, you will learn how to install Docker and set up your local environment to run the n8n hosting in your machine, which is the second option.

Prerequisites

Before diving in, ensure your Mac is ready. The following list demonstrates everything you need to complete this blog guide.

• Hardware/Software:
• A Mac running macOS 10.15 or later.
• At least 4GB of RAM (8GB recommended for smooth performance).
• An internet connection for downloading Docker and n8n.
• No prior experience needed: I will guide you through everything.

Install Docker Desktop

Firstly, please download the latest version of Docker. You can do this in two ways.

The first option is to use the installer from Docker’s website.

• Go to the official website and choose the suitable version for your machine: https://www.docker.com/products/docker-desktop/
• Click on the button “Download for Mac …” to get the installer.
• Open the .dmgfile. (typically, it is downloaded and saved in the Downloads folder)
• Drag the Docker icon to your Applications folder.
• Open Docker from Applications. It might ask for your Mac password to install helpers, enter it and allow.
• Docker will start up. You'll see a whale icon in your menu bar. If it asks to sign in, you can skip or create a free account (not required for this).

The second option is using the Homebrew installation method.

• Go to the Homebrew page for Docker: https://formulae.brew.sh/formula/docker
• Copy the installation command and open a terminal window.
• Paste the command into the terminal window and wait for the completion.
• Open Docker in a similar way as the above method or using the spotlight command.

Then, verify installation:

• Open Spotlight (Cmd + Space), type "Terminal," and open it.
• In Terminal, type: docker --version
• You should see something like "Docker version x.x.x". If not, restart Docker or your Mac.

Tip: If Docker won't start, check System Settings > Security & Privacy > General for any blocked items and allow them.
