Misc FAQs
*Where Is The Mac's Library Folder? "Library" used to be located in the User's folder but as of MacOS7 and newer, it is now invisible. You can either MacWorld link or find it by typing "Library" in the Help window and that should make it temporarily appear as a selection in the "Go" menu.
*Where is the Steam Apps Folder? For Mac: Library>Application Support>Steam>SteamApps. For PC it is located inside the Steam Application folder. If you have a Steam shortcut on your desktop, right click it, and select Open File Location to quickly navigate to the Steam folder.
*Where are my Steam Games Saved Games? That depends on the Game. See Misc Game Links for some Save Game Location links. For the Mac, if you dont know, a good place to look for a game folder for your specific game is in the Application Support (Library>Application Support).
Installing Steam on Your Mac
*Install Mac Steam- This link will immediately download Mac Steam: http://store.steampowered.com/public/client/steam.dmg. If the link expires go to Store.Steampowered.com and locate the "Install Steam Now" link on the right side of the page.
The default install location is to place Steam in your Applications folder. However, you can put it anywhere you want. When using my MacBookPro, I placed Mac Steam on my external drive. So I downloaded Mac Steam, opened the .dmg file and installed it there by simply dragging the Steam application from the .dmg file to the desired location.
*Launch Steam- Establish a Steam account if you have not done so all ready. By default it is going to automatically install the SteamApps folder in your Library>Application Support>Steam Folder. If you have a teeny weenie hard drive and need to move Steam Game content out of your home drive/partition, see the next section.
Specific Game Help
Vampire The Masquerade: Bloodlines
*The game will not run under Mac Steam. For information on running this game under Bootcamp/Windows/Steam see Windows Gaming On A Mac FAQ and look for the Specific Game Help Section of that guide. It is found in Part 2 of this Guide. This link needs an update.

*How to Save Game Data When Reinstalling Steam From Scratch- In other words how to avoid having to re-download your Game Library? Before reinstalling Steam navigate to the Steam Folder (Library>Application Support>Steam) and copy the SteamApps and UserData Folder to another location. After reinstalling Steam, put these folders back into the Steam folder. After these steps, if it says a game is not ready to play, tell it to download and hopefully it will sense the content is all ready there and quickly validate it.

Part 3: Establishing Additional Steam Libraries and/or Moving Mac Steam Content
When Steam is installed it automatically places a Steam Application Folder in your Library>Application Support>Steam>SteamApps. Inside the SteamApps folder, game installs will be located inside the common folder. BTW, the Steam folder is not to be confused with the Steam Application which by default resides in the Application folder or wherever you installed it.
Due to space requirements, if you desire to keep your Steam installed games in another location, Steam now allows you to have multiple active Steam libraries. Follow these Steps:
Establish Additional Steam Libraries
The advantage of this method, as compared to the old (symbolic link) method is that you don't have to move all of your games to the new location. If you for instance want to keep a few games on your internal MacBook drive, but move others to an external drive, this will work completely fine. Also, Steam won't freak out when you launch it without the external drive, as it would with the symbolic link method. BTW, the symbolic link info has been moved to the archived section of this guide.
- Create a folder- with an appropriate name at your desired location (partition or hard drive) for a new Steam Library.
- Create a new Steam Library- Within Steam (Preferences > Download > Steam Library Folders), designate this folder as a new library. Steam will automatically put a SteamApp Folder in this location.
- When you purchase/download a game from Steam, there will be a box that allows you to choose which Steam Library location to install the game.
- Very simple!
*Moving A Steam Installation and Games- PC Centric Link
*Mac Info:
- Activate a new Steam Library as described in the previous section.
- Navigate to the new Steam Library Folder- Navigate to the folder you designated as a new Steam library folder. Look inside the "SteamApps" folder and verify, that a folder named common exists. If no games have been downloaded to that location common may not exist. If its not there, create it.
- Move the game folders from the original SteamApps/common folder to the Steam Apps/common folder in the new location.
- Help Steam Find This Game- Remember the moved game was not download through Steam to this location. Instead it was manually moved over.
- Find the Steam AppID of the games moved game. It can be identified in the URL of the Steam Store page of the game (for Civ V that would be "http://store.steampowered.com/app/8930/", where "8930" is the AppID) or look it up here.
*The appmanifest file identifies the game for Steam- Move the "appmanifest" file with the same number from the old SteamApps library folder to the new SteamApps folder (not to the "common" folder). For Civ V, that file is called "appmanifest_8930.acf".
- Remove the game data from the original SteamApps/common folder. Throw it in the trash, but dont delete until its verified that the desired result has been achieved.
[*]Launch Steam. If all is well, the game status will be Play.

Part 4: Archived Info
Stop!
This section includes old info that was originally included in this guide. There is no need to review it, unless you want see how to make a symbolic link related to Steam or to be nostalgic.
Old Links
*Have not verified this content since 2013- Source Finagler- a 3rd party app by Mark Douma that will assist you in moving your Steam game content (the SteamApps folder) out of your Steam folder and on to an external drive or a different partition without having to use the Terminal. Separate Link.
*A Brief Tutorial on Symbolic Links- MacOSXHints.com. (Note Aug 2014: Symbolic Links are no longer required to add or move a Steam library.)
Old Updates
Steam Change: 26June2010 Alert A fundamental change in the physical organization of Steam on your Mac took place in 2010. Via the update, the "Steam Content" folder was renamed, the "SteamApps" folder and moved to the Library>ApplicationSupport>Steam folder.
* Warning! If you previously moved your Steam Content using this guide before June 2010 and decide to rename your "Steam Content" folder to "SteamApps" you will break the symbolic link you previously created. Either leave it alone or start from scratch and create a new symbolic link using the Terminal as per this guide.
* For Those of You Who Used This Guide to Create A Symbolic Link Prior to 26Jun10
...back in the beginning of June2010, when Steam game content was located in the Steam Content folder and kept in the Documents folder, your Steam setup should still work. As of 26Jun2010 if you previously used the symbolic link instructions to move Steam content out of your Documents folder, you will now see that the Steam Content link is no longer in your Documents folder. It has been moved to the Library>Application Support>Steam folder and it has automatically been renamed SteamApps. At least that is what happened in my case. In addition it points to the "Steam Content folder" you previously moved to another location and most importantly, your Mac Steam application should still be working!
Instructions for Creating a Symbolic Link to Relocate Steam Game Content
*The Problem: As of 26June2010, Mac Steam automatically installs games into your Library>Application Support> Steam folder in a folder called "SteamApps" and you don't have enough internal drive space to install games there.
*The Solution: The current work around is to put these games on an external drive or another partition by moving the SteamApps folder, and create a symbolic unix link in the Steam folder that points to the new location. When Steam launches, it looks for the SteamApps folder in the Steam folder, but there it is directed to the SteamApps folder in the new location.
*MacOS Note: Don't get confused if you are new to the Mac. The "Steam Application" is different than the Steam Folder that sits in the Application Support folder. The Steam Application (that launches Steam) is a MacOS Package. It is an application folder that is made to look like an application icon. If you click it, it acts like an application and will launch Steam. If you right-click it, a menu will open with a choice to show contents. Unlike Windows, the MacOS is very forgiving for dragging applications and content around. As you move things around, do not place the Steam application inside the Steam folder. Although I have not verified, I think this would be asking for trouble.
*My instructions are for specifically creating a SteamApps folder on an external drive, but you could do the same thing on another partition. Please note that Valve has indicated it will fix this problem in the future. When exactly? I don't know. -Hunt'n.
*You may have experience creating an "alias" within OSX, and may have used an alias to to point at another file in a similar manner to this. However for this situation, an OSX alias will not work. Instead you must create a symbolic link using a helper program (listed below) or the Terminal.
*Caution Some serious ***** can happen in the Terminal if you really mess it up, but on the other hand entering Terminal commands is not that hard. How is that for waffling?
Archived Guide Updates
*Mar 2013 Update Valve confirmed that the Mac version of Steam does not allow for creating a new Steam Library on another partion/hard drive from within the Steam application. The instructions for creating a symbolic link in this guide still applies for Mac Steam.
*Feb 2013 Update: As a reminder, this discussion focused on Mac Steam. Steam is now supposed to allow you to establish a new Steam App folder on any drive you desire, except in practice it does not work (for me). If you want to see, launch Steam, select Prefences>Download+Cloud tab (Preferences found under Steam menu, top of Finder window, not within Steam App Window.) An establish "Steam Library Folder" menu choice is located in a box that makes reference to "adding new steam folders on multiple drives" but if clicked on, it appears not to allow navigation to another drive. I've submitted a ticket to Valve and am awaiting a reply.- Huntn.
*Sept 2012 Update: FOR PC: The Steam Beta allows you to choose Steam Install Locations. See this PC centric RockPaperShotgun link. It speaks of adding "-dev" description to the Steam.exe application. Note, we don't have .exe applications on the Mac. And I don't know how this applies to moving Steam game content after the initial Steam install on your Mac. I assume that what you can do in Windows Steam will be about the same as Mac Steam, but I know where assumptions have gotten me in the past. As I become aware of more info, I'll post it. As far as I know, the instructions in this guide still apply. -Huntn 020913.
Original Instruction on How to Move Steam Content.
For moving Steam content the following info is outdated, although the process still works. Create a Symbolic Link to connect Steam to a Steam Library in a location different from the default library>SteamApps location. The downside of this process is that it only allows for one Steam Library, while the current method described previously allows for multiple Steam libraries. In addition I have not verified that Source Finagler still functions properly and the other old method, working with the Terminal is a pain.
You have two choices:
*Choice Number One: is to download MarkDouma.com's Source Finagler, download link: SourceFinagler app and follow the directions. The idea is that you are 1)moving your Steam Apps folder to a new location and then 2) using this app to create a symbolic link that goes into your Steam folder. I tested this application in June 2011 and it worked well. This is by far the easiest and quickest method.
*Choice Number Two: Is to use the Mac's Terminal Application to create a symbolic link, telling Mac Steam where to find the new location of the SteamApps folder. See the next section.
Using the Terminal
The SteamApps folder is where Steam stores game content. These steps creates a new unix symbolic link in your Steam folder (where the Steam Application sits) that points to the SteamApps folder location some place other than the default location (Default Location: Library>Application Support>Steam>Steam App folder). In my case, I want my Steam game content to be on my external drive.
WarningProceed at your own risk!!!
- To start out, install Mac Steam. This link will immediately download Mac Steam: Steam Client. If the link expires go to Store.Steampowered.com and locate the "Install Steam Now" link on the right side of the page. The default install location is to place Steam in your Applications folder. However, you can put it anywhere you want. When using my MacBookPro, I placed Mac Steam on my external drive. So I downloaded Mac Steam, opened the .dmg file and installed it there by simply dragging the Steam application from the .dmg file to the desired location.
- Launch Steam. Establish a Steam account if you have not done so all ready. By default it is going to automatically install the SteamApps folder in your Library>Application Support>Steam Folder. Shut down Steam.
- Locate the "SteamApps" folder in your Steam folder and drag this to the new desired location, where it will be copied. The assumption is that you are moving this folder to a different drive/partition. Therefore the folder will be copied and the original folder will remain in the Steam folder. But we don't want the original SteamApps folder sitting in the Steam folder, so move the original SteamApps folder from your Steam folder to the trash. Hold off on emptying the trash until you know you have a working copy of Mac Steam with the content in the new location.
- Open the Terminal application, located in your Utility folder. (In your Mac Finder along the top look for the "Go" pulldown menu> Utilities>Terminal). When you launch the Terminal a window opens that has a command line that starts with something like: MyMac:~ jharris$ (where jharris is the user).
- Type in this command ln -s (with a space between "ln" and "-s", followed by a space. Don't forget the space after the "-s"! If this space is not there, the command will not work. Note the command "ln" consists of the small letters LN, not IN). Your Terminal command line should look something like this:
MyMac:~ jharris$ ln -s
- Open the window that shows the new location of your SteamApps folder (the one you just moved). Left click on this folder and drag it to the Terminal Window then release it. This will copy a path to your Steam Content folder. (In my case "/Volumes/WDMac2/" is a partition on my external drive. The folder name is SteamApps. Your command line should look something like this now:
MyMac:~ jharris$ ln -s /Volumes/WDMac2/SteamApps
[*] Open your Steam folder. (In the Finder along the top look for the "Go" pulldown menu> Home>Library>Application Support folder). The "Steam" folder is in your Application Support folder. Click on the Steam folder, drag it to the Terminal Window, and release it. The path to your Steam folder will automatically pop in with a space between it and the previous part. After you've finished this step, you may notice a back slash (\) between Application and Support. This is normal. In the Terminal for the folder named "Application Support" it indicates there is a space between the two words. Your Terminal command window should now look something like this:
MyMac:~ jharris$ ln -s /Volumes/WDMac2/Steam\ Content /Users/jharris/Library/Application\ Support/Steam
[*] On the Terminal command line, type in the name of the link that will be placed into the Steam folder (by using this Terminal command). Right after the word "Steam" type in this syntax with no space: /SteamApps. Your terminal command line should now look something like this:
MyMac:~ jharris$ ln -s /Volumes/WDMac2/Steam\ Content /Users/jharris/Library/Application\ Support/Steam/SteamApps
[*] Select the Terminal Window, and now hit the "Return" key to enter the command. A new command line will appear that looks like:
MyMac:~ jharris$
Quit the Terminal. If you have formatted this command correctly, a new alias of your SteamApps folder should show up in your Steam folder. Verify. Now launch Steam and see if it worked.
