How to get herobrine minecraft for macbook pro? (Version 1.7.5) without a mod?

I'm sorry to say but herobrine was never actually in the game, The initial photos of him was a mod.
There are some good Herobrine mods though

There isn't a way. Herobine was never in the game, it was a spooky story someone wrote years ago that took on a life of its own.

There's no way to have Herobine without mods.

Herobrine does not exist in vanilla minecraft.
