Installing Homebrew 🔗

Open a terminal and enter the following command.

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

During installation, follow the prompts, including confirmation requests and password entry.

Once installation finishes, run the following command to verify it.

brew --version

If installation succeeded, a version is displayed as follows.

Homebrew 4.3.18

Installing packages 🔗

Find the package you want under supported packages and install it.

For example, search for Notion, copy the command shown on the page, and paste it into the terminal.

https://formulae.brew.sh/cask/notion

brew install --cask notion

Notion installation complete

A completion message appears when installation finishes.

You can find the installed application in Launchpad.

Troubleshooting 🔗

Configuring environment variables 🔗

If brew does not work after installation, you may need to configure the environment.

Enter the following command in the terminal.

echo "eval "$(/opt/homebrew/bin/brew shellenv)"" >> ~/.zshrc
source ~/.zshrc

Reopen the terminal and run brew to check that it works.

brew --version
brew doctor # 홈브루의 상태 확인

Conclusion 🔗

Homebrew can install, uninstall, update, and search for packages.

It simplifies package management and lets you manage package versions.

You can even create packages of your own.

It is an almost indispensable tool for MacBook users, so I recommend trying it.
