# Install Brew on a M1 Mac

> How to install Homebrew on macOS Monterey with a M1 chip.

```sh
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
echo 'eval "$(/opt/homebrew/bin/brew shellenv)"' >> ~/.zprofile
eval "$(/opt/homebrew/bin/brew shellenv)"
```

## Usage

1. Run `uname -m` in the Terminal of your choice and verify it outputs `arm64`
2. Run the command above
3. If you have not installed the Xcode Command Line Tools, brew will automatically install them for you
4. After the installation completes, run `brew doctor`
5. If the output of `brew doctor` is `Your system is ready to brew.`, you are done
6. If `brew doctor` returns issues, resolve them according to the provided instructions
7. You may want to set up Homebrew's shell-completion at this time
