Installing Minecraft mods on a Mac

UPDATE: This post has been updated in How to install Minecraft mods on a Mac.

My son is obsessed with Minecraft. He knows everything there is to know about the game, he has Minecraft toys, Minecraft books, he plays the game at school, and if we let him, he’d be at the computer all day and night 7 days a week. A few weeks ago he started asking for Minecraft mods. I had no idea what he was talking about so I looked it up and have since added some to his game.

A Minecraft mod is an add-on for the game which you can download and that adds extra features and functionality. For instance, there’s a mod called TrainCraft which adds engines and tracks so that you can build trains. Mods are not made by the the company that owns Minecraft and consequently are unsupported by them. So if you install a mod and break your game, you’re on your own.

I thought I’d write a brief guide on how to install mods on a Mac for other hassled parents out there.

Before you can install any mods, you need to download and install Minecraft Forge. You can download it from here:

If you don’t have Java on your computer, you’ll need to get that first.

Once you’ve downloaded Forge, navigate to the downloads folder, right-click on the file (it will look something like forge-xxxx-installer.jar) and choose “Open”.  Make sure the “Install client” button is selected.


Click “OK” and wait for the install to complete.

Now you need to create a mods folder on your Mac. To do this, you need to find the Library folder in your home directory. Unfortunately this is hidden in Mac OS versions Lion, Mountain Lion, and Mavericks. If you’re using Mavericks, the latest version at the time of writing this, then the process is quite simple. Navigate to your home directory with Finder, then from the Toolbar select View > Show View Options. Tick the box next to “Show Library Folder” right down the bottom.


If you’re not using Mavericks and/or don’t have the “Show Library Folder” option, then the other way to find this folder is to open it using a terminal. To do this, go to Applications > Utilities > Terminal. In the terminal window type: open ~/Library.

Once you can see your Library folder, go to Library/Application Support/minecraft

Create a directory inside the Minecraft folder called mods. Now you’re ready to install some mods. Find a mod on the web, download the .jar file for the mod, and stick it in the Library/Application Support/minecraft/mods folder. That’s it!

Now run minecraft. Before you click “Play”, choose the “Forge” profile from the drop-down box.


There’s a “Mods” button you can click to see which mods are active with your game:


If one of your mods crashes the game (this is not unusual), then you can navigate to your mods directory at Library/Application Support/minecraft/mods and put the suspect mod in your trash.
