I have Minecraft 1.12.2

I'd like to use the Mine Little Pony Mod with LiteLoader so I downloaded liteloader for 1.1.2, made a mods folder in ..../Library/Application Support/minecraft/mods and inside placed mod-minelittlepony-1.12.2.1-mc1.12.2.litemod. I selected liteloader and clicked play but I still see the original game.

I noticed that a new folder 1.12.2 was created inside mods so I also copied the mod-minelittlepony-1.12.2.1-mc1.12.2.litemod there but it didn't help.

Is it possible to play this mod with this version of Minecraft? Can anybody tell me where I'm going wrong please?
