iOs - Crashes on launch when Metal is enabled on iOs 9.2.1 (Unity 5.3.2p2)

The following error occurs in iPhone 6 and iPad Pro:

/BuildRoot/Library/Caches/com.apple.xbs/Sources/Metal/Metal-55.2.6.1/Framework/MTLRenderPipeline.mm:992: failed assertion `sampleCount (8) is not supported by device.’

Using Unity 5.3.2p2. Metal and OpenGL ES are enabled. Auto Graphics API selected.

If Metal is removed, it works but GL ES is extremely laggy on iOs 9.2.1

iPhone 6 and iPad Pro has a list of previous problems with Graphics AI:

5.3.2 - Black screen
5.3.2p1 - Hangs on launch screen
5.3.2p2 - Hangs fixed but Metal needs to be removed, otherwise it crashes.

EDIT: Removing antialias on render textures which was set to 8 fixed crash. But Black screen is back =Z

This post has the same problem: I'm a bit confused about "Skinned Mesh Renderer" - Unity Engine - Unity Discussions

Thanks for the support.

We had a similar issue with iOS + Metal and Shader Preloading using Unity 5.4.0 Beta15. So basically disabling shader preloading on Graphic Settings solved for us.
Another problem that cause a black screen is to SetResolution, but can’t remember exactly which Graphic API was…
