# Debug Metal graphics

> Debug Metal-specific graphics issues that arise in your project.

Unity's [Frame Debugger](/engine/6000.6/manual/analysis/graphics-performance-profiling/profile-rendering/frame-debugger/frame-debugger.md) supports Metal and should be the first tool you use to debug graphics issues in a Unity application that uses Metal. For more in-depth, Metal-specific graphics issues, [Xcode](https://developer.apple.com/xcode/) provides graphics debugging tools such as API validation and shader validation.

> **Note:**
>
> Enabling validation increases CPU resource intensity, so only enable it for debugging purposes.
