Why Use Homebrew for Installation?

Homebrew is a popular package manager for macOS that simplifies the installation process of software. By using Homebrew, you don’t have to worry about manual setups, dependencies, or conflicting software. Homebrew handles everything for you, making it the ideal way to set up software like Ollama effortlessly.

Prerequisites for Installing Ollama

Before we dive into the installation process, make sure you have:

A Mac running macOS 11 Big Sur or higher. If you're not sure about your macOS version, click on the Apple logo in the top-left corner of your screen, then select About This Mac.
Homebrew installed. If you haven't installed Homebrew yet, follow the instructions on the official Homebrew website. In a Terminal window, run:
1 2bash /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
An active internet connection for downloading Ollama & any required dependencies.

Step-by-Step Guide to Installing Ollama Using Homebrew

Step 1: Open Terminal

To get started, you'll need to open your Terminal application. You can do this by either searching for 'Terminal' in Spotlight or navigating to Applications > Utilities > Terminal.

Step 2: Update Homebrew

Before installing any new software, it’s a good idea to ensure your Homebrew is up to date. In Terminal, run:

1
2

bash  
brew update

This command updates Homebrew itself along with its formulae, ensuring you have the latest available versions of software.

Step 3: Install Ollama

Now it’s time to install Ollama! In your Terminal, enter one of the following commands:

1
2

bash  
brew install ollama

OR, if you prefer using the Cask version:

1
2

bash  
brew install --cask ollama

This will automatically download & install Ollama along with any dependencies required for it to run smoothly.

Step 4: Verifying the Installation

To check if Ollama was installed successfully, type:

1
2

bash  
ollama --version

You should see the version number printed in the terminal. If you don’t see this, double-check your previous steps.

Step 5: Initializing Ollama

Once you've installed Ollama, it’s time to get it up & running. Type:

1
2

bash  
ollama serve

This command starts the server, enabling you to start interacting with the models.

Pulling and Running Language Models

With Ollama installed, you're now ready to pull & use powerful language models.

Step 6: Find Available Models

Ollama supports a wide range of models. To find a list of available models, you can visit the Ollama library page. Popular models include:

Llama 3.1
Mistral
Code Llama

Step 7: Pull a Model

Once you’ve chosen a model, you can pull it using the following command. For example, if you want to pull the latest version of the Mistral model, run:

1
2

bash  
ollama pull mistral:latest

This downloads the selected model to your local machine for use.

Step 8: Running the Model

Now, you can interact with the model! To run your pulled model, use the command:

1
2

bash  
ollama run mistral:latest

You can type in prompts to see how the model responds. For example:

1
2

bash  
ollama run mistral:latest "What's the capital of Spain?"

This will return the answer instantly.

Troubleshooting Common Issues

Error: Permission Denied
If you encounter a permission issue, ensure you're not trying to execute commands that require root access. Sometimes, Homebrew can have permission conflicts. You can resolve these either by checking your file permissions or using
1sudo
if absolutely necessary.
Model Loading Issues
If models won’t load, ensure they’re compatible with your version of Ollama. An occasional error might suggest that the model has updates. When this happens, run:
1 2bash ollama pull [model-name]:latest
This will ensure you have the up-to-date version of the model waiting for you.
