How to Install Minecraft Mods Using Forge on Windows, macOS, and Linux Servers

This tutorial will show you how to install the Forge add-on and upload mods on an already existing Windows, macOS, or Linux Minecraft server. We will also cover the differences between Forge and mod launchers to help you decide.

An Introduction to Minecraft Mods

If you’re a fan of Minecraft, chances are you’ve dabbled in mods at some point. Mods are user-made modifications to an original game that can change pretty much anything. From new items and blocks, to resource packs and interface changes, mods offer a way to make the Minecraft experience unique. In this blog post, we’ll give you a brief introduction to mods and how they work.

What Are Minecraft Mods?

Mods are user-made modifications to an original game that can change pretty much anything. Usually, Minecraft mods include new items, blocks, resource packs, interface changes, and overall quality-of-life improvements for players. The main charm of mods is the ability to change pretty much anything to make the Minecraft experience unique. However, it’s worth mentioning that each mod needs to be downloaded and installed on both the server and client to work.

How Do Mods Work?

Most mods are created by passionate fans who want to improve their favorite game. To do this, they use a tool calledMinecraft Coder Pack (MCP). MCP allows modders to decompile and recompile the game code so they can make changes without affecting the original game files. Once they’ve made their changes, they package up the code into a mod file that can be distributed and installed by other players.

How to Install Minecraft Mods

Now that your Minecraft server is running and the JDK has been set up, we can proceed with the Minecraft mod installation process.

Step 1. Install Minecraft Forge

The most popular modding add-on is Minecraft Forge. It allows users to install and manage mods on the Java Edition of Minecraft. Check the following steps to install Minecraft Forge on a Windows Minecraft server. The installation process will be similar for Linux and macOS users.

1. Go to the official Minecraft Forge website and download the recommended version.
2. Wait for 5 seconds and click on SKIP:

3. Once downloaded, open the Forge installer. Select Install client and press OK.

4. The client version will enable players to join the Forge server. If an error message about a missing Minecraft profile appears, ensure that the default Minecraft launcher is installed and working.

5. Rerun the installer and select Install server. Specify the directory used by your vanilla Minecraft Server. Ignore the warning message and proceed with the installation.

Open the newly created folder and double-click the run file. The Minecraft server with Forge will start. An error about the EULA will appear – look for the eula.txt file and open it. Change the eula=false line to eula=true. Once that’s done, open the run file again.

Step 2. Download the Mods You Want

The next step involves downloading Minecraft mods. We recommend using popular sites like CurseForge or MinecraftMods.

In this tutorial, we’ll be setting up Just Enough Items (JEI), an excellent first mod. Open the website and check the Minecraft version indicated on the mod page – your game must match it. Once that’s done, click on Download:

Keep in mind that some mods come in .zip archives, so you’ll have to extract them before installation.

Step 3. Copy the Mod to the /mods Folder

It’s time to install some Minecraft mods. No matter your operating system, the process will be very similar:

1. Open the mods folder of your vanilla Minecraft installation. Its location will differ depending on your operating system – we’ll talk about finding it below.
2. If the folder is not there, create a new one and name it mods.
3. Copy and paste the downloaded mod to mods. Do the same for the mods folder located in your Minecraft server installation directory.

Locating the Mods Folder on Windows

The mods folder of your Minecraft client will usually be located in the .minecraft folder. The full path is Users/{Windows-Name}/Appdata/Roaming/.minecraft .

Alternatively, you can find it by pressing Control + R, typing in %appdata%, and hitting Enter. Look for the .minecraft folder – once you’ve found it, open the mods directory and paste your mod files there.

Locating the Mods Folder on macOS

The default directory for the Minecraft client is ~/Library/Application Support/minecraft.

You can easily access it by pressing Command+Shift+G to open Finder and entering ~Library -> Application Support -> Minecraft.

Locating the Mods Folder on Linux

To find the Minecraft client directory on Linux-based systems, open Terminal and run the following command:

xdg-open ~/minecraft

Step 4. Check the Mod Installation

Once you’ve installed a mod, it’s important to check if it’s working correctly. Do it by running Forge following these steps:

1. Open the Minecraft launcher, select forge from the dropdown menu at the bottom left corner, and click Play.

2. Once the Minecraft main menu has loaded, click on Mods.

3. All the installed mods will be displayed on the left sidebar, including Just Enough Items (JEI) we installed earlier.

4. If you want to check if the mods work on your server, select Multiplayer and add its address. In this example, we are running both the client and server versions of the game on the same machine, so the Server Address will be localhost.

5. Once connected, we can confirm that the JEI mod is active.

What to Do if Mods Aren’t Working?

In case your mods aren’t functional, check out the following troubleshooting tips:

• Make sure that you have installed Forge.
• Check if you’ve selected forge in the Minecraft launcher.

• Ensure that the mods are installed both on the server and client instances of Minecraft.
• Double-check if the mod version corresponds to the Forge version and that there are no duplicate mods.
• Make sure the downloaded mods have come from a reliable source and that you’re running the official version of Minecraft.
• Double-check the mods directory.
• Some mods have dependencies which must be installed.

How to Install Minecraft Mods with a Mod Launcher

Mod launchers allow users to install modpacks in under a few clicks. They usually contain hundreds of mods that are handpicked by Minecraft community members. This lets players play modded Minecraft without tinkering with manual mod installation.

Step 1. Choose a Mod Launcher and a Modpack

Note that mod launchers are separate from the default Minecraft launcher – you will need to download and install them separately. Some of the best launchers include CurseForge, ATLauncher, Feed the Beast (FTB), and Technic.

In this tutorial, we’ll be using the Technic launcher to install the Tekxit 3.14 Pi modpack.

Step 2. Install a Modpack

1. Download, install, and run the Technic launcher.
2. Find a modpack on Technic and Install it – this will set it up for the Minecraft client.

3. Find the same modpack on the Technic website and click Server download.

4. Create a new folder for your modpack and extract all the files there.

5. Double-click on the minecraft_server file to start your server. When the EULA error, locate eula.txt, open it and change the eula=false line to eula=true. Once that’s done, run the server again.

6. Once the server starts, players will be able to connect to it via the Technic Launcher.

Conclusion: That’s it! You have now successfully installed Forge and added mods onto your Windows, macOS, or Linux Minecraft server. Installing mods is a great way to enhance your gameplay experience by adding new content and features into the game. Be sure explore all of CurseForge in order find more great mods for your server!
