I have seen youtube videos of people with mods, Their Minecraft main menu says, instead of texture packs, "Mods and texture packs" I believe this to be the option to turn of mods and turn them back on... I can get mods but can't turn them off!
I am not familiar with a system that allows you to disable/enable mods, unless you are talking about Magic Launcher.
It was formerly done with Forge! But not anymore.
It actually was done with early releases of Minecraft and the Mods feature actually didn't work and just took you to the texture packs folder! Look at the change logs on your Minecraft launcher if you want to check it out. But you really can't get an older version of Minecraft, since it's againt Mojangs Terms Of Service!
How can I get my menu to have this option?
