How to download the Copious Dog Mod for Minecraft on a Mac Computer?

I keep trying to download it from many different websites but overtime i do, it says The Java JAR file "Copious-Dogs-Mod-1.6.2.jar" could not be launched." and I'm not really sure what to do.

You have to install Forge - http://files.minecraftforge.net/...forge.net/

Forge will create a mod folder in your minecraft folder, this is where you out your mod.

Alternatively and better in my opinion is to download ATlauncher - https://www.atlauncher.com/downloads

On the launcher, install Minecraft Vanilla and in the mod options, choose Forge and click add new mod and search for your mod. It will install everything for you.
