How to install Mods in Minecraft 1.6.2

How to install mods in Minecraft

Written to work with version 1.6.2

  • Note  – this is kind of tricky and tedious, and will require you to get a bit ‘under the hood’ of your computer. I’ve done my best to explain this in detail here but I realized this is a bit ‘Text heavy”, so you may want to view some video tutorials (see links below) that show you visually exactly what to do or check out the Minecraft Wiki page ( You can also do a google search for “How to install mods on minecraft” (and make sure the answers you read are published recently and are for the version of minecraft you are currently using. Anything written or recorded before July 2013 won’t work (for version 1.6.2)
  • Also a few warnings;
    • Some mods can cause Minecraft to crash, don’t be surprised if this happens, it’s ok, it’s not going to hurt your computer. If it does crash, just delete what you’ve changed and the normal Minecraft will still work.
    • Many mods don’t necessarily work well with other mods, if you are trying to install several them install them one at a time, test them as you go, and make a backup copy of your setup before you proceed so if one of them breaks your installation you don’t need to start all over again.

How Minecraft is installed on your computer

First a little background, there are really 2 different parts to a Minecraft installation;

  • Minecraft Launcher – This is the program you run to start Minecraft. It’s where you select what account you log in with and what profile you are using. This should be installed in the same location as the rest of the applications on your computer
  • Minecraft game directory – This is where the actual files the computer runs are located. These files are located in more hidden directories on your computer and a ‘normal’ user wouldn’t normally ever even see these files. In order to mod minecraft you need to be able to find these files. Along with the Minecraft application itself there are other important folders in this same directory that you will need to access to install custom maps or Texture/Resource packs.

How to access your Minecraft game directory;


  1. Launch Minecraft.
  2. Select “Mods and Texture Packs”
  3. Select “Open Texture Pack folder”
  4. Go up one level
    • Mac OS X
      • On a Mac OS X system the game directory is located inside the Library folder in your user account. By default Mac OS X hides this folder, in order to make it visible you need to issue a specific command using the Terminal application (located in Applications/Utilities/Terminal). Once you run this application just type the following and press return afterwards;
      •              chflags nohidden ~/Library
      • Once you’ve typed the above you should now see a Library folder in your home directory alongside Documents, Downloads & Trash.
      • Open the Library folder, then open the Application Support folder
      • In the Application Support folder you’ll find a minecraft folder, this is what we’re looking for
    • Windows
      • (?) Located in AppData/.minecraft/ (?)


The new Launcher lets you pick different ‘profiles’ to run when you start Minecraft. This is important to understand in order to run mods because you will need to create different profiles for your different modded versions of Minecraft so you can choose which version you wish to run. You pick which profile you wish to use by running the Minecraft Launcher and then, in the lower left part of the the Launcher window (to the left of where you press PLAY) there’s a drop down menu of the different profiles. The files for the different profiles are located in the ‘Versions’ folder in your Minecraft game directory.

Installing Mods with Forge

Many Mods require you first install the Forge mod (links below). This mod helps adjust Minecraft to make it much easier to install other mods. Installing this is fairly simple, you just download and run it and it will mod Minecraft and install itself. Note – Forge it updated regularly and you’ll see some some mods that will say ‘requires Forge version #### or higher’. You’ll want to keep a note of what version of Forge you have and repeat the installation procedure to upgrade it when you need to.

Installing Forge

    1. Make sure the Minecraft application or Minecraft Launcher are not running
    2. Download the latest Forge installer from
    3. Find the file that was downloaded (probably in your Downloads folder) and run this installer by double clicking on it. Your computer may warn you this is a file downloaded off the internet, click ok.
    4. This gives you several options, you want to choose ‘Install client’. If it works correctly it will give you a message saying it’s been correctly installed.
    5. Now when you start Minecraft you’ll see a Forge profile listed over in the bottom left.
    6. Select the Forge profile, then press ‘Play’ to start minecraft.
    7. You should now see a ‘Mods’ folder on the main screen, if you do, it worked. (yay)
    8. Quit minecraft & the Launcher
    9. Open your Minecraft game directory (See earlier in this document, this is located in Library/Application Support/minecraft folder on the mac)
    10. There should be a mods folder in there now
    11. Put any Forge compatible mods in there (again, only add one at a time and test as you go)
    12. Run Minecraft and it should load that mod (you can check by clicking on the Mods button when Minecraft launches and see if the mod you installed is listed there.

Installing mods that DON’T require Forge

  1. Open up the Library folder in your home directory, then open Application Support, then Minecraft and finally versions
  2. (~/Library/Application Support/minecraft/versions/ )
  3. If you don’t see the Library folder in your home directory type the following in a terminal window;
  •              chflags nohidden ~/Library
    1. In this folder you’ll see a folder names something like 1.6.2. Select this and go to File menu/Duplicate
    2. This will make a new folder named 1.6.2 Copy
    3. Rename the Folder to something unique like – 1.6.2-mods (cant have any spaces)
    4. Rename the files in that folder to match the name you picked ala;
      • 1.6.2-mods.json
      • 1.6.2-mods.jar
    5. Edit using textedit the .json file above and change the first line – id= to match the name you picked
    6. At this point you’ve made a copy that wont auto update (yay!)
    7. Rename the jar file by changing .jar to .zip
    8. Double click and open the .zip file
    9. This will make a folder named 1.6.2-mods
    10. Copy or move the files from the mod you’ve downloaded into this folder.
      1. Easiest way to do this is to open two finder windows and adjust them so you can see both on the screen at the same time.
      2. Make sure to open one with the contensts of the mod you wish to install.
      3. The other should be the /versions/1.6.2-mods/1.6.2-mods/
      4. then, in the mod contents folder, do ‘Select All’ (Command A) or under the menu on the top of the screen under the Edit menu
      5. Drag the files over into the 1.6.2-mods folder
      6. Answer yes to all questions about replacing files
      7. When it’s done you can close the mod contents window
    11. In a new finder window open the profile folder (~/Library/Application Support/minecraft/versions/1.6.2-mods)
    12. Open the 1.6.2-mods folder (~/Library/Application Support/minecraft/versions/1.6.2-mods/1.6.2-mods)
    13. select all
    14. press and hold control and then click once on the mouse
    15. select compress
    16. find the file
    17. Drag it into the other window so it’s in the profile folder
    18. rename to 1.6.2-mods.jar
    19. cross your fingers and hope it worked
