Step-by-Step Installation

1. Download Miniforge3 (Conda-Forge Version)

Go to the official website: Conda-Forge Miniforge

Download the installer for macOS (ARM64), which is optimized for Apple Silicon.

2. Install Miniforge3

Once downloaded, open a terminal and run:

bash ~/Downloads/Miniforge3-MacOSX-arm64.sh
bash ~/Downloads/Miniforge3-MacOSX-arm64.sh
bash ~/Downloads/Miniforge3-MacOSX-arm64.sh

3. Verify Installation

After installation, check if Conda is installed:

/Users/your-username/miniforge3/bin/conda <span>--version</span>
/Users/your-username/miniforge3/bin/conda <span>--version</span>
/Users/your-username/miniforge3/bin/conda --version

(Replace your-username with your actual username.)

If Conda is installed correctly, you should see the version output.

Fix: “Command Not Found” Issue After Installation

If you get a “command not found” error when running conda, follow these steps:

1. Add Conda to PATH

Open your terminal and run:

<span>echo</span> <span>'export PATH="/Users/your-username/miniforge3/bin:$PATH"'</span> <span>>></span> ~/.zshrc
<span>source</span> ~/.zshrc
<span>echo</span> <span>'export PATH="/Users/your-username/miniforge3/bin:$PATH"'</span> <span>>></span> ~/.zshrc
<span>source</span> ~/.zshrc
echo 'export PATH="/Users/your-username/miniforge3/bin:$PATH"' >> ~/.zshrc
source ~/.zshrc

Enter fullscreen mode Exit fullscreen mode

If using bash instead of zsh, replace ~/.zshrc with ~/.bashrc.

2. Initialize Conda for Your Shell

Run the following command:

/Users/your-username/miniforge3/bin/conda init zsh
/Users/your-username/miniforge3/bin/conda init zsh
/Users/your-username/miniforge3/bin/conda init zsh

Enter fullscreen mode Exit fullscreen mode

For bash, use:

/Users/your-username/miniforge3/bin/conda init bash
/Users/your-username/miniforge3/bin/conda init bash
/Users/your-username/miniforge3/bin/conda init bash

Enter fullscreen mode Exit fullscreen mode

Then restart your terminal.

3. Test Conda

Try these commands:

conda <span>--version</span>
conda info
conda <span>--version</span>
conda info
conda --version
conda info

Enter fullscreen mode Exit fullscreen mode

If they work, your installation is now properly configured!
