No, Apple created their own graphics API called "Metal" and basically left their OpenGL support to rot. Since Apple makes the GPU drivers for OSX themselves, they have total control over what and what isn't supported.
So, that makes three Mantle-like APIs: Metal, DX12 and Vulkan.
Of course, people already began working on Vulkan-Metal wrappers, so you can re-use the Vulkan code on OSX, but using Metal under the hood.
