Steven Moran - How to get A Game of Thrones mod for Crusader Kings II working on your Mac

How to get A Game of Thrones mod for Crusader Kings II working on your Mac

UPDATE (2018/06/17): I haven’t bothered to run the Game of Thrones mod in a few years; I find, for the hassle, it doesn’t actually make that much of a difference over the original Crusader Kings… but William recently commented on this post and suggested that this method works a charm, so give it a shot:

UPDATE (2016/08/22): Since this is such a popular post and is still one of the top results for how to install the mod, here are the updated instructions:

If you, like me, bought the game from way back in the day, they’re no longer updating the game for whatever reason. Thankfully, if you go into your purchase history, they give you a Steam key that you can redeem on Steam for the latest version of Crusader Kings II. Now onto the instructions:

Step Action
1 After you uninstall the MacGameStore version of the game (if applicable), then install the Steam version, run it for the first time so that it recreates the Paradox Interactive folder in your Documents folder then quit the game.
2 Download the latest version of the mod from here (make sure to download the Zipped Files version) and make sure to take note of which version number of the CK2 game it’s compatible with. That should match for consistent results.

You can find out which version of CK2 you have installed in the game’s launcher:

3 In Finder, go to YOUR-USER/Documents/Paradox Interactive/Crusader Kings II/ and create a folder called A Game of Thrones and another folder called mod.
4 Unzip the A Game of Thrones folder and the A Game of Thrones.mod file from the ZIP you downloaded into the newly-created mod folder.
5 Run the game and select A Game of Thrones in the mod panel of the launcher.
6 Rule.

Note: This entry does not relate to art or design, in the traditional sense of my site. I am writing this to help others that have run into similar problems.


If you’re like me, you might have heard about the game Crusader Kings II through Penny Arcade TV’s Extra Credits show in an episode called Games You Might Not Have Tried #4 and you might have thought, “hm, that looks like a really neat Civilization-type strategy game with a pretty rich story…” But then the narrator said, “Game of Thrones mod…” and you were hooked.

Now, as a primarily console-based gamer, I have to take deep breaths when I hear about a cool PC game because odds are that it won’t work on my Mac, but luckily, in this case, Crusader Kings II is available for PC and Mac, so I went ahead and bought my copy from the Mac Game Store. I downloaded my copy of the Game of Thones mod here, but you can do a quick Google search for the latest version if you’re reading this post months after I wrote it.

Because I purchased my copy of Crusader Kings II through the Mac Game Store, it was a direct download and all I had to do to install the game was drag the app from the .dmg file to my Applications folder. This is where the trouble starts, if you bought the game to play the Game of Thrones mod.

The issue

After figuring out where to put the mod, when launching the game and selecting the mod, the game crashes instantly. This is because the path specified in A Game of Thones.mod doesn’t point to the actual folder with all of the mod’s resources like it should.

The 5 minute solution

It turns out, this isn’t an incompatibility between the mod and the Mac version of the game, it’s an issue with a directory in the A Game of Thones.mod file itself, which was developed by a team who had assumed the mod would be used by a PC user and hadn’t been able to test it on a Mac. Here are my step-by-step instructions on how to get the mod working on your Mac in less than 5 minutes:

Steam users: If you bought your copy of Crusader Kings II through Steam, I’ve added steps to the instructions below to get the mod working for you as well. There may be a few extra and unnecessary steps, but I recommend you follow them all because as inelegant as they may seem, they work. Follow the steps as written originally unless you see a Steam heading below the original step.Note: The Steam portion of this guide was made in collaboration with my commenters. As I don’t own the Steam version, I can’t test these steps personally, but they have worked for others. If you find a way to optimize them at all, comment and let me know.– Steven

Step Action
1 Unzip the A Game of Thrones mod.
2 Go to your applications folder, find Crusader Kings II, right-click it and select Show Package Contents.Steam: Skip this step, go to step 3.
3 Navigate to Contents / game / mod and copy all of the files from the original ZIP here.

Steam: Navigate to Library / Application Support / Steam / Steamapps / common / crusader kings ii / mod / and copy all the files from the original ZIP there. (The copied files within the mod folder should still look the same as in the screenshot above.)

If your Library path is hidden, in the Finder, click on the Go menu and then hold down Option or Alt on your keyboard and the Library will appear in the list. Click on it to navigate to Library.

4 Open the file A Game of Thones.mod with TextEdit.
5 In the Path field, replace the directory “mod/A Game of Thones” with “/Applications/ Game of Thones” and replace user_dir with #user_dir.

Save the file and exit TextEdit. It might be locked and ask you if you want to overwrite the original or create a duplicate, make sure you overwrite the original.

Steam: In the Path field, replace the directory “mod/A Game of Thones” with “Users/YOUR USERNAME HERE/Library/Application Support/Steam/SteamApps/common/crusader kings ii/mod/A Game of Thrones” and replace user_dir with #user_dir.

Save the file and exit TextEdit. It might be locked and ask you if you want to overwrite the original or create a duplicate, make sure you overwrite the original.

6 The next time you run the game, select the A Game of Thrones in the Select mods to play field before you select Start CKII.Screenshot of Crusader Kings II launch windowNote: The game may still crash the first time you do this, but if it does, launch it again and it will work.Steam: Unzip the A Game of Thrones mod again and this time, do not modify the A Game of Thones.mod. Navigate to your Documents folder and open the Paradox Interactive folder. Open the path to Crusader Kinds II and create a new folder inside named mod. Copy the contents of the unzipped A Game of Thrones folder to this new mod folder. Perform the “normal” step 6.
7 Enjoy playing out Robert’s Rebellion, and good luck avoiding marrying one of Walder Frey’s hundred children!Screenshot of A Game of Thones Crusader Kings II mod running

    Thanks for commenting. Hopefully we can troubleshoot this and have it working for you so you can enjoy Robert’s rebellion.

    Can you share screenshots of the directories and A Game of Thones.mod in TextEdit? I can provide an extra set of eyes to make sure everything looks in order.

    Just to test, try removing the .app part of the directory in the A Game of Thones.mod file. (/Applications/CrusaderKings2/Contents/game/mod/A Game of Thones)

    We’ll figure this out.

    The mod and steps will work with the Steam version as well, but since Steam installs the game to another directory, you’d have to do some poking around and find the mod directory to copy the files to / change the directory in the mod file.

    I’m out of town at the moment, but when I get home, I’ll add a comment with the Steam information (directories).

    OK, I’m just going to keep posting.

    I finally found the proper place to put the mod. The trick was you have to go into finder click on the ‘Go’ drop down menu. Then hold down ‘option’ and ‘Library’ will appear. You can now find the steam folder and steam games in this path – /Library/Application Support/Steam/Steamapps/common/crusader kings ii/mod/A Game of Thrones v0.2″

    Still hasn’t worked for me though.

    Joseph – If the mod is showing up when you’re starting the game, that means that you’ve put the files in the right directory, so you’re on the right path. Could you post a link to a screenshot of the directory you have the .mod file in and one of the .mod file opened in TextEdit? If it’s crashing, it’s probably because the path in the .mod file is incorrect, try using the one below.

    Tim – Thanks for posting your progress. Try using this directory: “/Library/Application Support/Steam/Steamapps/common/crusader kings ii/mod/A Game of Thrones” (assuming the .mod file is named “A Game of Thones.mod”).

    I’m going to do some sleuthing this evening and will post more as well as modify the original post to include Steam instructions as well for future visitors who may not read the comments.

    I finally got it working after about ten hours of playing around with everything. Not sure why it works but it does. Quick summary is this.
    1. Use the technique I previously mentioned to find the files.
    2. I had initially just moved the whole downloaded mod folder (A Game of Thrones v0.2) into the mod fold (as above path shows) What you need to do is copy its content in to the mod folder. ( As you mentioned in the OP)
    3. This is the bit I fluked that made it work. Open the paradox Interactive folder in your document folder open the path to crusader kings II, create a mod folder.
    4. Extract the downloaded mod again and copy into this. DO NOT edit the .mod file this time.
    5 For some reason this allows it to work. God knows why. God probably doesn’t care.

    This is the edit I did to the .mod file –

    name = “A Game of Thrones”
    path = “Users/(put your user name here)/Library/Application Support/Steam/SteamApps/common/crusader kings ii/mod/A Game of Thrones”
    user_dir = “A Game of Thrones”

    I hope this helps any other poor Mac/Steam users.

    OK, two things that I notice:

    Alright, I feel like I’m getting close.

    I changed the user name, and unzipped the mod duplicate directly into the document, which took away the extra ‘2’. The game still launches to the European map, even when I click on the mod to select it.

    Eric –

    1. Did you place an UNedited .mod file in the document file path?

    2. Not sure if it was you or not but saw on another forum someone was using their Steam Username instead of the Username on the computer.

    Let us know if either of those fix the problem.

    Also, @ Drew & Tim, you mentioned putting an unmodified .mod file in the Documents folder. What ‘Documents’ folder are you speaking of? Is it a Steam thing?

    Right I think I’ve cracked it, well it works for me anyway!
    What I did was update to the latest CKII patch 1.07b and then downloaded the latest version of the mod V.0.3.2 from here:
    Then followed the instructions i.e strip out ALL of your old mod files and then copy the new ones ONLY to the Documents/paradox interactive/crusader kings II/mod

    Initially this still didn’t work so I went into the A Game of Thrones.mod file and added a # in front of user_dir so it looks like this:

    name = “A Game of Thrones”
    path = “mod/A Game of Thrones”
    #user_dir = “A Game of Thrones”
    replace_path = “history/characters”
    replace_path = “history/diplomacy”
    replace_path = “history/provinces”
    replace_path = “history/titles”
    replace_path = “history/wars”
    replace_path = “common/buildings”
    replace_path = “common/cultures”
    replace_path = “common/dynasties”
    replace_path = “common/landed_titles”
    replace_path = “common/minor_titles”
    replace_path = “common/nicknames”
    replace_path = “common/on_actions”
    replace_path = “common/opinion_modifiers”
    replace_path = “common/religions”
    replace_path = “common/traits”
    replace_path = “common/objectives”
    replace_path = “common/graphicalculturetypes”
    replace_path = “events”
    replace_path = “decisions”

    Then in mod/a game of thrones/gfx I deleted the ‘loading screens’ folder and BOOM the bastard worked!!!

    Hope that helps

    Then, just as you did in the first “A Game of Thrones” folder, delete the loadscreens files, otherwise the game will crash after the loadscreen.

Perhaps something is not translating correctly for the macs and there is nothing that can be done 🙁

    I am having a similar problem. I also bought the game for the GOT mod. Got it to run, but after a few minutes of gameplay it crashes to desktop.
    There is an error after the MOD loads, that says the checksum is wrong.
    I have noticed that it crashes when I try to do specific things, like marry – crashes every time. As long as I just poke around the map it’s fine, but if I try to advance the game at all, crash.
    I have tried running it on all the video settings, similar results.

    Anyone else experience that checksum error?
