How to install Minecraft mods on a Mac

My most popular post of all time by far is a documentation page about how to install Minecraft mods on a Mac. Nothing else I’ve ever written has come anywhere close to the popularity of that post. I guess no one really cares how I spent my weekend but clearly a lot of people want to know how to hack Minecraft.

I wrote that old post after going through the process of installing mods for my then seven-year-old son who was determined to play mods. That was almost four years ago and is now out of date so here’s an updated version. Enjoy!

There are three main steps – install Forge, create a mods folder, install mods. I’m using macOS High Sierra.

Install Forge

  1. Download the latest version of Minecraft Forge from here (choose the Installer): http://files.minecraftforge.net

  2. Navigate to the downloads folder and find the file you downloaded. It will end with xxxxx-installer.jar. Right-click the file with your mouse and choose “Open”.
  3. Select “Install Client” from the next screen and click OK.

Create mods folder

  1. Open Finder on your Mac and go to Go > Library in the menu.

  2. Go to Application Support > minecraft in Finder and create a new folder called mods. This is where your mods will go.

Install mods

  1. Find the mod on the web you want to install and download the file to your computer. It will be a file ending in .jar.
  2. Drag and drop the downloaded file into your new mods directory in the ~/Library/Application Support/minecraft/mods folder.

You’re now ready to play the new mod!

When you launch Minecraft be sure to select Forge from the Play menu.

  1. Hah – once upon a time, when I still wrote a technical blog – I wrote up the instructions to install WordPress on a fresh install of Linux – with Apache, MySQL, PHP, and so on. It was by far the most read and commented on post I ever wrote. I’m guessing these days the likes of StackOverflow have killed technical how-to posts…

    1. Ah, that’s good to know. I’ve wondered about writing some how to WordPress posts on my blog and whether they’d be very popular. They wouldn’t be particularly technical though.

  2. I’ve done this but it keeps crashing and refuses to let me open the applications with any mods in the folder (aside from forge itself).

    1. If Minecraft keeps crashing then there’s a problem with the mod you’re trying to use. Some mods have issues that cause Minecraft to crash. Try with a different one.

  3. Thanks for creating this! FYI, when I right-clicked on the downloaded installer jar, I had a choice of what to open it with. I knew to choose “Jar Launcher” (not various archive utilities or Java IDEs), but other people might not.

  4. I’m having an issue where after hitting go there is no library tab. Does anyone have any idea as to why?

    1. Try opening Finder and clicking the Go menu and choosing Home. Then click on the View menu and choose Show View Options. At the bottom of this next screen check the box next to Show Library Folder.

  5. I don’t have a folder for minecraft in my library? I have a mods floder in my minecraft application and forge but nothing works for me.. Can anyone help?
