To create the symlink you will be using Terminal which can be found in Applications > Utilities. This is because you will be creating a symbolic link, also known as a symlink, to reference the file path of your user data stored in another location. By following this workaround your entire Electronic Arts folder will be stored and updated on the external drive although your game will think it is being stored locally on your Mac internal storage (for the equivalent instructions for Windows, head to Crinrict’s site here). This is for those running out of space on their Macs and wanting to save their user data – Saves/Tray/Mods etc.
