10.11 and on I use Metal, but what should I use for earlier versions? On Xcode on a computer I have that has OSX 10.8.5, it didn't offer an OpenGL game template for OSX, only for iOS. It only offered SpriteKit. I'm not sure SpriteKit is ideal for 3D rendering.
I don't want to use a game engine, those are bloated and slow, I want to use a low-level graphics API, so what's the best alternative to Metal for versions that came before it?
