Removing Steam and Steam games

Just dragging the Steam program to the Trash will not fully uninstall Steam. The additional steps below are required.

With the Steam application active, click the Steam menu and Quit Steam to exit Steam.

1. Open Applications and drag Steam to the Trash.
   
2. Click Go in the menu bar, hold down the option key until you see the Library folder, and open that folder from the drop-down.
   
3. Navigate to Library/Application Support/Steam
   
4. Delete Steam data from your computer with one of the following options:
   
   If you don't want to lose any game data: delete all files and folders in /Steam EXCEPT FOR the /SteamApps folder (this contains your game downloads and any local save files.)
   
   If you're removing all Steam data from your computer: delete the entire Steam folder.
   
   
5. Empty the Trash by selecting Finder -> Empty Trash
   

With these files deleted, you can reinstall Steam if you are troubleshooting a problem.
