MacInstallForge Instructions

This script will help install Minecraft Forge (for Minecraft modding) onto your Mac.

1. Download and Play Minecraft at least once for the version of Forge you want.
2. Download Minecraft Forge and place it in the same folder as your Minecraft app. (Download Link, make sure to grab the "Installer" for the Minecraft version you want)
3. Right/Two Finger Click on the Raw button for the MacInstallForge.sh file below. Click "Save Link As...", and save to the same folder where your Minecraft app is located. (Make sure the format is a "shell script".)
4. Go to the folder that you have all your files in so far, and go to the gear dropdown menu, and click "Copy "FolderName" as Pathname" (example)
5. Open a Terminal and type cd and press Command+V. The command should look something like this:

cd /Users/cole/Documents/Programs

Press Return.

6. Type these commands in the same Terminal with a Return keypress after each:

chmod +x MacAutoForge.sh
./MacAutoForge.sh

7. Click "Install Client", then "OK".
8. You're done! Enjoy your mods!
