Minimal Cataclysm Client (Fast):

Download 4.3.4 WoW Cataclysm Client is complete, if you have followed the steps above. After finishing, you will need to configure your file. It needs to point at the exact Cataclysm server that you would like to play on.

What is a World of Warcraft Cataclysm Client? is actually providing just that. A Cataclysm Client for World of Warcraft, made by Blizzard, is necessary in order to start playing.

Since Blizzard no longer provides the particular expansion, Cataclysm, there are many different Cataclysm Private Servers that do, in their own modified way. To connect to a World of Warcraft Cataclysm Server, you need a 4.3.4 Cataclysm Client.

Explaination of what a Cataclysm World of Warcraft Client is

At we know the importance of providing working Cataclysm Clients. That involves, no broken links or broken clients, after downloading. Therefore, we make sure to test our provided links on our site.

World of Warcraft: Cataclysm is created by Blizzard Entertainment. It’s a MMORPG game, and Cataclysm is often known as Cataclysm or Cata. It was released the 7th of December 2010. That means it’s actually over 10 years old!
Blizzard no longer provides the Cataclysm expansion anymore, resulting on it not being possible to officially play that anymore. Unofficially though, there are however many possibilities to play it.

The un-official possibility, is through Cataclysm Private Servers, which are a popular (and free) choice nowadays’. At Zremax we provide you a list of servers in general, and also a particular list of servers for Cataclysm. And in here, we provide you with the Cataclysm Client that is necessary to play on the servers.

What is a Full WoW Cataclysm Client? (Torrent)

A Full Cataclysm WoW Client is a torrent, basically providing you with a full version of the game. In theory though, the provided clients are never 100% of the game. There is usually content ‘behind’ the scenes, that is not included. The original Cataclysm version of the game by Blizzard was therefore bigger size wise. Versus a full WoW Cataclysm Client that you will find nowadays.

It’s a nice feeling knowing that you have an 1-1 version of the original Cataclysm client. But it’s not really noticeable while playing to be honest. All the regular content, is already downloaded and compressed into the Full Cataclysm WoW Client. It’s mostly data behind the scenes that may be missing, to explain it quickly.

A Full WoW Client of Cataclysm has the clear benefit that it does not download the game while playing. After you have downloaded a 4.3.4 client, it can get enjoyed in high experience. This involves reduced FPS issues or sudden drops. In that case, a full client is usually more stable than a fast minified version.

What is a Fast Cataclysm WoW Client? (Mini)

A Fast 4.3.4 Cataclysm WoW Client is a minified version of the game. Basically, it contains a “download-while-playing” concept.
This means that you can get started playing very quickly. But it also has the consequence of possible FPS issues and drops. To be very concrete, once you eg. create a Human character, it will take additional loading time. It needs to load the content, which would be the case for Elwyn Forrest in this case. That can get very disturbing for some people, whereas they should download a full client of WoW Cataclysm instead.

A Fast Cataclysm 4.3.4 Client can however be a perfect fit for those who are casually playing. As well as those who just want to get right into the game as fast as possible. This also prevents waiting a few hours for the game to complete downloading.

How do I download a WoW Cataclysm Client for Mac?

Downloading the Cataclysm WoW Client for Mac can be a little difficult in some cases. We will give you all the relevant information you need, to play Cataclysm on a Mac.
This part is only relevant for those who run Mac, and for those who want some additional knowledge. To clear it out, this part is not related to setting up Cataclysm on a Windows PC.

The procedure for setting up a WoW Cataclysm Client on a Mac, depends on your OS system.
If you run an older version of Mac OS that can also run 32 bit, the steps are reduced. If that’s the case, scroll up to the top of the Article, to the first answered question. At that location, you can download the Mac client we have provided.

UPDATE: Good news – Down below, we included a stable guide to run Cataclysm on a Mac, with an OSX like Catalina that requires 64 bit apps.

Different steps for 64 bit Cataclysm Mac Users Catalina

In case you are however using an updated OS of Mac, the steps are rather complicated. It requires the apps to be 64 bits, unfortunately, such as with Catalina OSX! We will however sum that up, and make it less complicated for you.

Cataclysm was the first expansion by Blizzard where they started working on 64 bit apps. Unfortunately, they did however not finish it fully, meaning that it can risk containing weird issues ingame.
You can download the Mac 64 bit WoW . After doing so, you will need to copy the WoW 64 bit folder into the Mac client. That was provided in the top of this article. The WoW 64 bit file you just downloaded should be used, instead of the WoW 32 bit file. The WoW 32 bit file was originally included in the Mac download.

After doing so, you can launch the game and pray that the ingame is somewhat functional. The game will show the version you are using at the bottom left hand corner of the login screen. An example of this could display like this: Version 4.3.4 (15595) (Release x64).

The reality for Mac users running Cataclysm is different

The steps above rarely provides a smooth experience for the Mac users. To achieve a proper experience while playing, the reality is different. An option is to use Parallels Desktop (Paid) for Mac. Alternatively, you can Bootcamp your Mac with Windows aside (Free) (stable).

Let me start by saying there’s no direct “64 bit Cataclysm Mac Client” that works well as of right now. Instead, we use other ways to get into the Cataclysm game on our Mac machine.

There is however a way to play Cataclysm on a Mac Catalina OSX, or similar OSX requiring 64-bit apps:

Option #1: Bootcamp. Can be a possibility, but complicated to set-up. Personally, I’ve previously used the last option where I’ve bootcamped my Mac with Windows aside. This worked well for me, meaning that I can enjoy the game smoothly again, with my Mac. It was however annoying that I had to split my resources, use disk space, use Windows and have to restart my machine every time I needed to play Cataclysm WoW on my Mac.

An option is that you to do the same. Of course, only in case you really want to play a Cataclysm Server on a Mac Machine. It can take a couple of hours to set-up the Bootcamp, and can be a little complicated. There are also other possibilities like VMWares where you can split your Mac up. This gets done when you open a program, into a selected OS like Windows, and then launch the game. But speaking from experience, it just never really provides the smooth gameplay.

Option #2: Parallels. Not recommended.

Option #3: The recommended method!

UPDATED: Option #3 – A new stable way to play WoW Cataclysm on a Mac with 64 bit / Mac Catalina on WoW Cataclysm:

You heard right! We now have a guide providing you with how you can play Cataclysm on a Mac containing Catalina or an OSX requiring 64 bit. This is the method we recommend.

Let’s get right into the guide on how to play Cataclysm 4.3.4 on your Mac Catalina OSX.

Personally, I’m using a Macbook Pro 2016, and the method works well. I have been using it for months, without any issues. Please note that this method is a paid Software that costs 40 USD lifetime. I bought it without any doubt because for me I knew it was worth it. You have to consider with yourself whether it’s worth it for you or not. I can however almost guarantee you that the Software, once buying, works flawlessly according to my tests.

1. Start by purchasing the Software, so we can proceed. You can purchase it HERE . You can choose a Trial or a Paid version. I recommend you to get the Paid version straight away because the trial contains some limited features and will stop working after 14 days. The other one will work permanently, lifetime wise, and you won’t have to set it up again after 14 days. I already tested it on several Mac machines, and haven’t had a single issue so far. Great job to the author of the software.

2. After clicking the link HERE we recommend you to get the second one, called “One Version”, like below:

You simply need to press “Add to Cart” on the One version, which costs 39.95 USD.
After you’ve paid, we can start setting it up.

3. Install and launch CrossOver. Now press on the button “Install a Windows Application”.
4. Now you have to select an Application to Install as the first step. In this field, search for “World of Warcraft”. Select it, and click continue. After doing so, click on the next tab called “Select Installer”, and then click on Choose Installer File. Now you need to browse to your WoW Cataclysm Client (For windows!), and find the WoW.exe file, and select it.
Note: If you don’t have a Cataclysm Client for Windows stored, then you can get the Cataclysm Client. Just make sure to get the Windows client version from it.

5. At the next tab (“Select Bottle Tab”), choose Windows 7, X64 Bottle.
6. Go to the Install & Finish tab and press on Install.
Now grab a cup of coffee, and let the software do its magic. It will be downloading some different tools that are necessary for the program to function properly.
After a bit, you will be prompted to agree to some installations. Simply, say yes to every prompt that comes up.

7. Give it a little patience and your WoW Cataclysm Program will finally launch on a Mac Catalina or Mac OSX that requires 64 bit apps! Notice how stable it actually runs. It’s really smooth and enjoyable. I’m in love with the software, and I’m happy to finally be able to log in and play “directly” through my Mac Catalina.

The next time you want to play Cataclysm WoW again, you can of course use the software, and you can also save the set-up, so you don’t have to do it every-time. In that case, open the CrossOver program, and then select the WoW Bottle that you created earlier, and click on “Run Command”, then select the WoW.exe from your Cataclysm WoW Directory, and press “Save Command as Launcher”, and press open.

After doing so, you will see the WoW icon below the Bottle tab. You can also drag the WoW Cataclysm Launcher from Crossover into your Desktop or Dock. This way you can get directly into WoW Cataclysm without having to open Crossover first.

Enjoy playing Cataclysm on a Mac Catalina Client now!

This gave you a few different options on how to proceed with this and play Cataclysm on a Mac. As well as how to download a WoW Cataclysm Client for Mac.

How do I download a 4.3.4 Client for Windows?

Downloading a 4.3.4 Client for Windows, is unlike Mac, very simple and straightforward. Start downloading the provided Cataclysm Client in the top of this page. Afterwards, you simply need to set it up.
You can set up your Windows 4.3.4 Client by changing your Realmlist file. The realmlist needs to be changed to the particular Cataclysm server you’re looking to play on. The file can be found at World of Warcraft\Data\enGB\ or the enUS folder.

In case you don’t know what realmlist the Cataclysm server you’re looking to play is, there’s help ahead. They usually provide it on their homepage. It always starts with set realmlist.
Alternatively, if you can’t find the realmlist for the server you’re seeking, you can attempt to find the particular server on our Cataclysm Private Server list, and then the realmlist will display at our “Details” tab.

Hopefully you now know how to play Cataclysm on a Windows Client.

Why do Cataclysm World of Warcraft Clients contain different sizes?

Usually Cataclysm Clients provided, have a different total size. There are many World of Warcraft Cata Clients around on the internet. Many of the clients are actually not the same, although that’s what you would assume. Some of the Cata Clients provide a larger size.
As a result, a higher % of the game is compressed into the client-files. Some of the clients are more stable than others.

Is it Safe to download a WoW 4.3.4 Cata Client?

There have however been reports that some users (by their ISP) however do receive copyright strikes from Blizzard. The users that actually do experience this, mostly get it from downloading the torrents. It mostly happens from the torents, which is a full client download, and not from the minimal ones. In order to secure yourself and prevent this, you can use a cloud based torrent client like Bitport.

UPDATE: I installed another 4.3.4 Windows client, this time direct from the Apollo wow website. Now I had a file without SET gxWindow “1”, so i added that line in the file.

I still get the same error message though when trying to install and launch in CrossOver… Still on a 2019 macbook pro 13″.

It only happens when loading character list with characters in it.
We got in a game only when we logged on realm, without created characters so we created one and got in. But then we could not back in because the character list again.
Please help.

It is Apollo-WOW. We downloaded their fresh client to be sure.
And we have Macbook Air M1 2020.

Thing is that only the load to character list looks like is causing the problem.
So if there would be some way to log directly to chosen character or something like that that could solve it if there will not be anything else..
