Here is a thread for Frequently Asked Questions about the Aspyr-published Civ4 and Warlords products for Mac OS X. For completeness, it also includes questions about running Windows versions of the Civ4 software range on Mac hardware using Apple's Bootcamp, or using virtualization software such as Parallels Desktop or VMWare Fusion.

I'll start it off with the questions I've seen most often. If I've missed a question (or got the answer wrong) then feel free to add it, and the answer, as a post in this thread, and I'll put a link to it here. I'm optimistically reserving a second post as a continuation of the index.

The format for each FAQ post should be:

Product: (Civ4, Warlords, BtS or All)

Platform: (OS X, Windows, Parallels, Fusion ...)

Question: ....

Answer: ....

If you have an unanswered question that you think others would also like answered then post it here as well. If it gets a definitive answer I'll consolidate it into a single post in the above format.

Question:
What are the current versions of Civ4, Warlords and BtS for Mac OS X?

Answer:
Civilization IV with the Rev C patch is at version 1.74 (52473a). This is the same as the current PC version 1.74.

Warlords with the Rev C patch is at version 2.13 (63968a). This is the same as the current PC version 2.13.

Beyond the Sword with the latest patch (Aug.25) is at version 3.19 (92131). This is the same as the current Windows version 3.19.

The main version number corresponds with the Firaxis version number for the PC version. The numbers in brackets are Aspyr build numbers.

Platform: OS X

Question:
How can I change display settings to switch between Windowed and Full Screen modes, or to change window size, or to choose the screen to use?

Answer:
A. Hold the Command (Apple) key down while launching Civ4 or Warlords to display a dialog box where you can set up the display configuration.

... or ...

B. While the game software is running, at the main menu select Advanced, or in the game hit Escape. Then, select Options from the next menu, and click the Graphics tab. You can change resolution and switch Full Screen mode on or off in this panel. You can't use it to change screens on a multi-screen Mac.

Question:
Can I change other settings that are controlled by the CivilizationIV.ini file?

Answer:
Yes. This file is in ~/Documents/Civilization IV/, or ~/Documents/Civilization IV Warlords/, or ~/Documents/Beyond the Sword/ and there are lots of settings you can adjust by editing it using TextEdit or another plain text editor.

Platform: OS X

Question:
Can I use mods that have been developed for the Windows version of the software?

Answer:
Maybe. There are several reasons why a mod may not work on the Mac version.

1. If a mod has been developed using the Windows Software Development Kit (SDK) to create a custom version of the game core DLL then it will not work as expected with the Mac version. There is currently no work around for this. We have to wait for Aspyr to create an SDK for the Mac version, and then recompile the mods to run in OS X. [Update: Brad Oliver of Aspyr has indicated that this capability is under development ].

2. Some mods contain incorrectly formatted XML text files, which Windows will still read but OS X doesn't. It is usually possible to edit these files to make them work on the Mac. Search this forum for people who have already done this, or post a request for assistance if your favorite mod hasn't been converted.

3. Some mods include Python code, and this may rely on the Windows Registry to find specific folders on the host computer. This code can be modified to work on the Mac.

Question:
When I select Check for Updates it says there is a new version and downloads a patch file. What should I do with this file?

Answer:
You can't use it. It is a Windows patch file, and will not work for the Mac version. You will have to use Aspyr's update for the Mac product, to vanilla v.1.74 or Warlords v.2.13 or BtS v3.19. You can find links for these in the sticky threads at the top of this forum list, or you can subscribe to Inside Mac Games to get a more direct notification.

Question:
Can I play other users in Multiplayer mode?

Answer:
Yes. You should be able to play Mac or Windows users by setting up a "Direct IP" connection to the computer that starts the game. You can also play by email, or use the Hotseat mode.

To play Windows players you must use the same versions on both platforms. The latest versions of Civ4 and Warlords include GameSpy compatibility for cross-platform play via the GameSpy servers.

You can use GameRanger to connect to other Mac users, or you can use Direct IP if you know the host computer's real IP address. For GameRanger, the host system may need to have port mapping set up to allow port #2056 through its firewall or Internet router.

Product: Civ4 for Windows (any version or module, include Warlords, Beyond the Sword, Gold, Chronicles, etc.)

Platform: Windows XP or Vista, via OS X and Boot Camp

Question: Can I run [fill the blank] on a new Mac?

Answer: Yes!

You will need [fill in the blank], a recent Windows install disc (post XP service pack 2 or later), and Boot Camp (http://www.apple.com/macosx/bootcamp/) (free). Please reference the Apple resources for installing Boot Camp, and the Microsoft instructions that came with your XP or Vista disc for installing Windows.

As an added bonus (should you have both versions of Civ4), you will find that the performance of Civ4 for Windows under Boot Camp out-performs Civ4 for Macintosh under OS X on the same machine. Please resist the temptation to tease us about that.

Yes, this true for the “low end” Macs. This advise also holds for all models of the Intel based Macs, even the first generation ones.

Question:
... from NinjaSmurf: greetings. when you say that you must play windows users with "the same version" does that mean you must be in bootcamp+xp+"same pc version of civ 4"? or can you run a mac version that is the same version number as the pc one? thanks in advance.

... and from rosynelson: Using a "Direct IP" connection between a Mac and Windows machine what versions of Civ IV Warlords should both platforms be running in order to play multiplayer?

Answer: The Mac player(s) and the Windows player(s) must all have software at the same versions.

Currently, most Windows players will have updated their Civ4 to version 1.73 and their Warlords to version 2.13. Mac players must have the same version of the corresponding software, whether they are playing the Mac software in OS X, or the Windows software in BootCamp or a Windows virtual machine. OS X BtS is currently version 3.17, so Mac OS X players will have to wait for a patch to version 3.19 in order to play against Windows players.

Product: All

Platform: Mac OS X

Question: Why are there almost NO mods for mac? oh and is there anyplace there are more mods?

Answer: There are a lot of mods for Civ4, Warlords and BtS. Check out the Creation and Customization forums. They are almost universally created by Windows players because there are far fewer Civ4 players on Mac than on Windows. In addition, the tools for graphics modding are almost non-existent on the Mac, and there is no SDK for the Mac versions.

In theory, mods should not be platform-specific. In a perfect world there would be the same number of mods for Mac as for Windows, and you wouldn't have to ask your question. In practice, every mod has to be tested with the Mac versions of Civ4 because they are often incompatible. The incompatibilities are typically:

- Text encoding errors in the XML files, usually by foreign language translators

- Use of Python calls that are not handled by the Mac - Windows registry calls, or v2.4 calls

- Use of the SDK to create a custom CvGameCoreDLL.dll file that alters game rules. The CvGameCoreDLL code is integrated into the Mac versions, so they simply don't work with a custom dll ... yet. Aspyr are said to be working on this.

We don't know how many of the mods that have been created are compatible with the Mac, because not many of them have been tested and reported here. That probably comes back to the fact that there are not many Mac Civ4 players. The compatible ones we do know about are reported in the other thread, where you posted about a mod that you have tested.

Question: Why has it stopped working? It just bounces in the dock, then ... nothing.

Answer: This appears to be related to the upgrade to QuickTime version 7.6 in January 2009. Various solutions have been posted here. They either involve reinstalling an earlier version of QuickTime, or the current version of QuickTIme, or reinstalling OS X using Archive/Install. At the time of this post, Aspyr are reported to be working with Apple to resolve the issue.

Question: If I'm buying BTS, do I need Warlords first? Does BTS include all of the differences that Warlords brought?

Answer: No, you don't need Warlords to install or run BtS.

Yes, BtS includes the game play changes that were introduced in Warlords, but you don't get the scenarios that shipped with Warlords.

Hi, don't know if it's the right place to post but I'm trying to play saved gamed posted on strategy & tips forum (ex: Emperor Cookbook...) but BTS says that the save is only for 3.2 version !!! Any ideas on how to use these kind of saves?

BtS version 3.2 doesn't exit as far as I know, on any platform.

Are you sure it says 3.2 and not 302? 302 is the saved game file version number for BtS 3.19. If you are running version 3.17 or earlier then you will need to upgrade BtS, as they only know how to read saved games at version 301.

Thanks Alan, it's exactly that. It says 302, my bad.

So I need to play 3.19.

I'm so bored, I bought BTS for mac and the DVD is not working anymore (don't know why!) so I downgraded to 3.17 as I'm forced to use a no-DVD tools that only applies to 3.17!

I'll send back the DVD to the shop see what they can do.

Thanks for the reply.

Question:
Can I upgrade the version of Rhye's & Fall or The Road the War that was installed with Beyond the Sword? Can I install the Windows versions of these mods?

Answer:
No.

These two mods Have custom DLLs in their Windows versions. The Mac BtS software does not support custom DLLs, so in order to deliver the mods, Aspyr had to compile special BtS applications with the DLLs embedded in them. The Windows versions will therefore not work.

I have Windows XP Professional installed on Parallels (running Snow Leopard), but I'm having trouble getting my custom mod to show up (a mod of Rhye's that required recompiling the DLL)...before I go through the trouble of installing Boot Camp and setting it up JUST to play that Civ mod, can anyone confirm if running it through Boot Camp will be just like running it on a PC? I'd really rather not invest the time only to find that it doesn't work if someone else already knows one way or the other...

Switching to Bootcamp *might* solve your problems, but I'm not optimistic. What happens when you try to run it in Parallels?

Have you run your mod successfully on a native PC? If so, it is surprising that it doesn't run in Parallels. The recompiled DLL should behave identically, and the only issues are likely to be with your mod's graphics.

the only native PC at my disposal is my girlfriend's 2003 IBM Thinkpad, which seems to display the start screen info correctly (my first clue on my own that it wasn't reading the new dll), but even with the sliders all the way down, it's a bit sloooooow to test the thing fully. Still, a step in the right direction.

I'd really rather not put boot camp on...if you or someone else has advice for making it work in parallels I'd really appreciate that. It's not that the mod doesn't run in Parallels, it's that it doesn't show up in the menu.

In XP on Parallels I'm going to put it in C:\Program Files\Firaxis Games\Sid Meyer's Civilization 4\Beyond the Sword\Mods, but it just doesn't appear at all.

DELETED. One person asking the same question in several places doesn't make it an FAQ.

no dice, I've spent the last four weeks learning C++ and altering Rhye's and Fall of Civilization to add the Celts as a playable civ.

Apparently, Macs won't run anything that doesn't use the unaltered DLL...this is because the original DLL (and Rhye's DLL) are included just for the checksum, and are not actually used by the Mac. The info from the DLLs are hard coded somehow in a workaround on the Mac install, so my choices are to use something that involves the original DLL (not possible as the mod has to exceed 18 civs) or Rhye's original (no good because all the stability info and stuff for the civ I created are in CvRhyes.cpp and necessitate a recompiled DLL to take effect...using the original DLL makes the Celts think they're Carthaginians and insisting on colonizing North Africa while ignoring Gaul and the British Isles...in addition to other issues).

This basically leaves me only the alternatives of getting it running in the PC install on XP Pro (running conveniently in Parallels 5.0 ...but i'm not having much luck so far) or installing a partition and Boot Camp with XP Pro and hope that after all that it finally works, even though it requires a separate startup to access.

...sigh...

Hmm. If the mod doesn't even show up in the menu when you select Load a Mod then there's something very odd going on. All it needs to see is the folder in the Mods folder. At that stage it doesn't even care if there's anything inside the folder.

I just created an empty folder called "Test Mod" in C:\Program Files\2K Games\Firaxis Games\Sid Meier's Civilization 4 Complete\Beyond the Sword\Mods\ in my copy of BtS in Parallels/WinXP. I started up BtS and selected Advanced->Load A Mod. The displayed list of mods included "Test Mod".

So I suspect BtS is not correctly installed, or you have not put the mod in the place you think you put it.

Alright, I've got it now (I think), it was just a matter of finding the right "Mods" folder (there are several), and making sure there were no old copies lurking around in wrong places. I got it to show up, the dll I've made appears to be working properly. On the first go around, the game crashed after I'd played a few turns, but I'm going to try it on chrystal mode without other things running on OS X...naturally, it only does me good if the system can handle it, but I do remember playing civ bts on Parallels 3 a year ago, albeit with the sliders down...

Sorry if this is the wrong place to post, but is there any information on how CIV BtS performs on the iMacs that use the ATI Radeon HD 4670 (256MB) graphics card?

When I check the Aspyr website for support info, that card isn't listed (the only cards listed are: 9600, 9650, 9700, 9800, X600, X800, X1600, X1900, HD 2400, 2600, 3870)

Question: So I am a simple player and don't know how to convert Windows-based scenarios and mods to Mac. So I was wondering if anybody has tested any of the popular World War II scenarios for Mac.

you cannot convert any one that uses a modified DLL (most of the good ones). The Mac has a DLL as a placeholder in the regular game and in rhye's, but it doesn't acutally read it for the game. Any altered dll will cause the game to use the default one anyway and crash the mod. The mac version is hard-coded with a workaround for the dll in the vanilla game(s) and rhye's mod ONLY.

on the upside, I bought the pc version and Crossover Games (a version of Wine for intel macs) and it works FANTASTICALLY...runs other pc programs too without requiring a windows install.

I can now run any mod or SDK software to mod my own...it's fast, it's stable and...well...i have not words for its awesomeness.

plus, the latest patch for the pc means no cd is required to run the game.

Will there be a civ 5 for mac?

Then, i load the mod and it loads fine but then i don't know which to select, play game, load game, warlords scenarios, scenarios, custom games or custom scenarios. If i play a scenario it either makes me instantly lose or only have workers in ancient times. please help.

I play Warlords on Mac. Is there a way to upload a saved game in a format that a Windows user can open? Somebody asked me to upload my game position for comments, and I have no clue how to do it. Thanks!:)

If you have not run with a mod then your Mac Warlords saves should be compatible with Windows Warlords. It's safest if you are both running the same version - v2.13 is the current version of Warlords on both platforms.

You can upload your save by clicking the "Go Advanced" button at the bottom of the appropriate thread. Type your message in the "Reply to Thread" editing area, and then click "Manage Attachments" in the "Additional Options" panel below it. Choose your Warlords save, click the "Upload" button, and then close the "Manage Attachments" window. Your uploaded file should be shown next to the "Manage Attachments" button. Click "Submit Reply" to post your message with its attached file.

I have a question about installing Warlords. Everytime I attempt to do so, it says that Civ 4 is not in a valid location. Where should I put it so that it is in a valid location?

Run the application installer program. It automatically puts all files where they belong.:)

This is on our "Current Patches" thread:



Please note that all Aspyr patches update the Civilization IV application. If a patch claims it can't find your Civ4 to update, click the "Other" button and navigate to the Civilization IV application you want it to work on.

Maybe this applies to the Warlords installer as well.

Well I tried moving it to the applications folder, but it still said it was in an invalid location.

I dont exactly know what the application installer program is lol.

It keeps telling me now that Civ 4 was installed incorrectly, and I have to uninstall it and install it again.

Ive already done that, haha.

If you have bought the vanilla DVD, there isn't an installer program. You just drag the Civ4 folder from the DVD onto your hard disk, usually to the /Applications folder.

When you run the Warlords installer, please can you say *exactly* what you see, in what order?

Ok, so I've done that first part for Civ 4.

When I double click the Warlords Installer, the following pop-up appears:

"Civilization 4 does not appear to be installed correctly. (Thats sort of the headline at the top)"

Then it says:

"The installation of Civilization IV (located at /Applications) is not valid. Install Civilization IV again to fix this problem."

Only thing is I did uninstall and reinstall, yet the same thing is popping up.

Have you run Civ4 vanilla since you installed it?

I guess I also have to ask: Are you sure you copied the entire Civ4 application FOLDER across from the DVD to /Applications, not just (a) the application file, or (b) a shortcut.

Hi, I understand that BTS on PC no longer requires a cd to be present in the drive, does anyone know if the same is true of the Mac version of BTS? I would buy it just for this! thanks

When I load up mods with custom leaderheads, everything seems to be running smoothly, but then I try to look at one of them (the leaderheads), and the program quits on me. I've recently been trying to use History Rewritten, but this problem has occurred. Is this something I can fix?

Does the game run with no problems without any custom leaders?

Is Antialiasing samples set to zero in the Options->Graphics screen? If not, try that. Non-zero values are known to cause display problems, though I haven't heard of it resulting in crashes, so this may not be the problem.

Other than that, I suggest you go into the Console application and open the CrashReporter log for BtS. You should have some crash reports from these events. If you post them here you may get some suggestions as to the cause.

By the way, how can I use other custom leaderheads in my game? I know how to download them, but I don't know how to actually use them. Of course, I should probably work out this problem first.

Shall we assume the answers to the other questions were yes/no/maybe?

That isn't the CrashReporter log. You need to use the menu on the left of the Monitor screen and navigate to FILES -> ~/Library/Logs -> CrashReporter, then click on a file called:

Civilization IV Beyond the Sword_[date-time when it crashed with this problem]-[your computer name].crash

Question: How do I take screenshots on Mac OS X?

Answer:

Command-Shift-3 saves a .png image file of your entire screen on your desktop.
Command-Shift-4 gives you a cross-hair cursor that you can use to select a rectangular area to save instead of the full screen.
Use Control with the above combinations to put the image on the Clipboard instead of straight into a file.
You can then use Preview's File->New with Clipboard to make an image document you can crop and edit and save in any format. Or you can paste it into another application window.

There is also a Grab utility in /Applications/Utilities/ that you can use to achieve these actions and more.

Mac OS has used the same key combinations for screenshots since 1984.

Here's a graphics issue I am having. All the Civs have the same yellow flag and no logo. Whether I am playing as the Ottomans (green flag) or Rome (purple), I still get the yellow flag with no logo.

Question: How can I play mods with more than 18 civs in the Mac version?

Answer:
Adding more than 18 civilizations in a third party mod requires a custom DLL, and the Mac versions of Civ4/Warlords/BTS/Colonization do not support these at all. The only way to play more than 18 civs is to run the recompiled versions of BtS supplied by Aspyr, which have the modified DLL code code built in. Road to War is an example.

Sorry if this has been answered elsewhere, i couldn't find it, but how can I stop Civ4 BtS from creating a folder in Documents (i.e. is there a way to move it somewhere else)?

Sorry if this has been answered elsewhere, i couldn't find it, but how can I stop Civ4 BtS from creating a folder in Documents (i.e. is there a way to move it somewhere else)?

Sadly no, at least not that I've found.

If you move it somewhere else, CIV will just create a new folder in Documents the next time that you launch it. I know because I have tried to move it. Some bright guy at Aspyr, most likely emulating a similar genius at Firaxis, hard coded it that way.

The road to war mod with
1936 - Global Assault (Hitler - Hirohito).CivBeyondSwordWBSave or
1936 - Global Assault.CivBeyondSwordWBSave
both have 30 playable civs.

That's correct. But those are recompiled versions of Civ4 created by Aspyr specifically including the Road to War DLL code. I have clarified my post to say you can't install a third party mod to play more than 18 civs.
