1.2 Installing Homebrew on Mac

Homebrew is a package manager for macOS that makes it easy to install software. Follow these instructions to install Homebrew on your Mac.

1.2.1 Steps to Install Homebrew

Open Terminal: You can find the Terminal application in the Utilities folder under Applications, or by searching for it using Spotlight (Cmd + Space and type “Terminal”).
Run the Installation Command: Copy and paste the following command into your Terminal and press Enter:
```
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
```
Enter Your Password: During the installation, Homebrew will use sudo to gain the necessary permissions to install software. You will be prompted to enter your Mac password. Type your password and press Enter.

Note: You won’t be able to see your password as you type. This is a security feature. Just type it carefully and press Enter.
Press Enter When Prompted: The installation script may prompt you to press Enter to continue at various stages. Follow the instructions and press Enter when prompted.
Add Homebrew to Your Shell Environment: Once the installation is complete, run the following command to echo and append the Homebrew shell environment setup to your .zprofile (if you’re using Zsh, the default shell on newer macOS versions):
```
echo 'eval "$(/opt/homebrew/bin/brew shellenv)"' >> ~/.zprofile
```
Apply the Changes to the Current Terminal Session: To apply the changes to your current terminal session, run:
```
source ~/.zprofile
```

1.2.2 Verification

To verify that Homebrew was installed correctly, you can run:

brew --version

You should see the Homebrew version number, indicating that the installation was successful.

That’s it! You now have Homebrew installed on your Mac and can use it to easily install and manage software packages.
