How to Install XQuartz on Mac?
Installing XQuartz is quick and straightforward.
- Download the latest version of XQuartz for Mac.
- Open the downloaded .pkg installer.
- Double-click the installation package.
- Follow the installation wizard to complete the setup.
- Restart your Mac if prompted.
- Launch XQuartz from the Applications folder.
- Configure your display or SSH settings if required.
If you use Homebrew, you can install XQuartz from the terminal instead, using `brew install --cask xquartz`. This installs the same official release without needing to open a .pkg file manually.
After installation, you can run local X11 applications or connect to remote Linux and Unix systems using X11 forwarding.
How to Uninstall XQuartz on Mac?
Since XQuartz installs system-level components outside your Applications folder, simply dragging it to Trash leaves files behind. To fully delete XQuartz from your Mac:
- Quit XQuartz if it's currently running.
- Open Terminal from Applications > Utilities.
- Run `launchctl unload /Library/LaunchAgents/org.xquartz.startx.plist`
- Run `sudo launchctl unload /Library/LaunchDaemons/org.xquartz.privileged_startx.plist`
- Run `sudo rm -rf /opt/X11* /Library/Launch*/org.xquartz.* /Applications/Utilities/XQuartz.app /etc/*paths.d/*XQuartz`
- Run `sudo pkgutil --forget org.xquartz.X11` to clear the installer record.
If you installed XQuartz through Homebrew instead, run `brew uninstall --cask xquartz` to remove it cleanly.
