Keeping your Homebrew packages up to date is essential for security, performance, and accessing the latest features. This guide covers everything you need to know about updating Homebrew and its packages on macOS.
What is Homebrew?
Homebrew is the most popular package manager for macOS, making it easy for developers to install and manage command-line tools and applications. Regular updates ensure you're running the latest, most secure versions of your installed software.
Update Homebrew Itself
Before updating packages, update Homebrew to its latest version:
brew update
This command fetches the newest version of Homebrew and updates the formulae (package definitions) from the Homebrew repository.
Update All Installed Packages
To upgrade all outdated packages at once:
brew upgrade
This command will update every package that has a newer version available.
Update a Specific Package
If you only want to update one specific package:
brew upgrade <package-name>
For example, to update Node.js:
brew upgrade node
Check for Outdated Packages
Before updating, see which packages have available updates:
brew outdated
This displays a list of all installed packages with newer versions available.
Prevent Specific Packages from Updating
Sometimes you need to keep a package at a specific version. Pin it to prevent automatic updates:
brew pin <package-name>
To allow updates again:
brew unpin <package-name>
Clean Up Old Versions
After updating, remove old package versions to free up disk space:
brew cleanup
To see what would be removed without actually deleting:
brew cleanup -n
Complete Update Workflow
Here's the recommended sequence for maintaining your Homebrew installation:
# Update Homebrew itself
brew update
# Check what's outdated
brew outdated
# Update all packages
brew upgrade
# Remove old versions
brew cleanup
# Verify installation health
brew doctor
Troubleshooting Common Issues
Permission Errors: If you encounter permission issues, avoid using sudo with Homebrew. Instead, fix the ownership:
sudo chown -R $(whoami) /usr/local/bin /usr/local/share
Formula Not Found: Run brew update to refresh the formula list.
Broken Links: Fix broken symlinks with:
brew link <package-name>
