Some games will not ask you and simply move on to the install, but luckily these ones tend to see the file in the new location and do the right thing. This will be a pop-up listing the two folders, the original and the new one. Most games will ask you where you would like to install it.Right click on the game again, select 'Install Game.'.In the Library, Right-click on a game and select 'Delete Local Content.'.In the finder, copy the SteamApps folder from your Library/Application Support folder to the new folder you added in step (5).Select the new folder, it will be added to the list.Click on the 'STEAM LIBRARY FOLDERS' button in the Downloads page.Click on the 'Downloads' tab in Preferences.

I made one called 'Steam Games' at the root of my big drive.

Create a symbolic link in this folder pointing to the place you moved the SteamApps folder to:.

Open up Terminal and change to the Steam folder by typing:.

Move the ~/Library/Application Support/Steam/SteamApps/ folder to wherever you want it to be.

If you really want to keep game data out of your home directory, you can make a symbolic link at ~/Library/Application Support/SteamApps/ pointing to somewhere else on your disk, perhaps in /Users/Shared/. Save files are kept elsewhere in your home directory, depending on the game. It's safe to exclude ~/Library/Application Support/Steam/SteamApps/ from your backups since no user data is kept there, only the game installs. Because of this, it's not really possible (or a good idea) to trick Steam into putting the game data in /Applications/ instead. It does this because different games may have different directory structures-unfortunately, not all Mac games come in neatly-packaged app bundles.

When you install a game, Steam places it in ~/Library/Application Support/Steam/SteamApps/ and creates an alias in ~/Applications/ which you can use to launch the game.
