# SCNRenderingAPI.openGLLegacy

Use the Legacy OpenGL API for SceneKit rendering in macOS.

## Declaration

```swift
case openGLLegacy
```

## Discussion

Discussion This option is available on all macOS systems supporting SceneKit. If you request the Metal rendering API for an SCNView object on a system that does not support Metal, SceneKit falls back to the Legacy OpenGL API.
