# How to install Homebrew, Composer, Git and WGET on macOS Sonoma, Sequoia and Apple Silicon (M1) Macs

NOTE: This post is a few years old and may be outdated, but I did just install the following on a new iMac M1 in 2022 and here’s what worked:

First, Git comes installed by default on most Mac and Linux machines.

To **check if you have Git installed**, open your Terminal and type

```
git --version
```

Hit return. If you don’t see a Git version follow these instructions to **install Git** on your Mac: [https://git-scm.com/install/mac](https://git-scm.com/install/mac)

Then **configure Git** with your email and name:

```
git config --global user.email "your@email.com"
```

```
git config --global user.name "Your Name"
```

Before installing Homebrew, you should ensure the Apple Command Line Tools are installed:

```
xcode-select --install
```

Then **install Homebrew** (see https://brew.sh/ for more detail, but this will get you there):

```
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
```

Add Homebrew to your PATH:

```
echo 'eval $(/opt/homebrew/bin/brew shellenv)' >> $HOME/.zprofile
```

```
eval "$(/opt/homebrew/bin/brew shellenv)"
```

Then **restart your Terminal** and run the following commands:

```
brew doctor
```

```
brew update
```

```
brew install git php composer wget
```

## Bonus: Generate a Modern SSH Key

In 2026, we recommend using **Ed25519** instead of the older RSA format. It is more secure, generates shorter strings, and is supported by virtually all modern hosting providers (GitHub, GitLab, Bitbucket, etc.).

**1. Generate the key:**

Open your Terminal and run the following command, replacing the email with your own:

```
ssh-keygen -t ed25519 -C "your@email.com"
```

*When prompted to “Enter a file in which to save the key,” just hit **Return** to use the default location.*

**2. Add your key to the SSH Agent:**

To ensure macOS remembers your key and doesn’t ask for your passphrase every time you reboot, run:

```
eval "$(ssh-agent -s)"
```

**3. Configure your SSH config file:**

Modern macOS versions require a small configuration change to persist the key in your Apple Keychain. Open (or create) your config file:

```
nano ~/.ssh/config
```

Paste the following into the file:

```
Host *
  AddKeysToAgent yes
  UseKeychain yes
  IdentityFile ~/.ssh/id_ed25519
```

*(Press **Control+O**, then **Return** to save, and **Control+X** to exit).*

**4. Add the key to your Keychain:**

```
ssh-add --apple-use-keychain ~/.ssh/id_ed25519
```

**5. Copy the key to your clipboard:**

Finally, copy your public key so you can paste it into GitHub or your server dashboard:

```
pbcopy < ~/.ssh/id_ed25519.pub
```

The key is now on your clipboard and ready to be pasted!
