When launching the HDRP graphic test on Metal, very often an error happen.

Unhandled log message: '[Error] Metal: Error creating pipeline state (Hidden/HDRP/CopyDepthBuffer): depthAttachmentPixelFormat is not valid and shader writes to depth
(null)'. Use UnityEngine.TestTools.LogAssert.Expect

How to reproduce step:
Run HDRP graphic test on Yamato:
https://github.com/Unity-Technologies/Graphics/tree/master/TestProjects/HDRP_Tests
and you get this result 80% of the time
https://yamato-artifactviewer.prd.cds.internal.unity3d.com/0c195f4e-5f04-4095-93d9-a4e056286e67%2Flogs%2FTestProjects%2FHDRP_Tests%2Ftest-results%2Ftest-results/TestReport.html

Note: None of HDRP people have a Mac, so we don't know if this happen locally or only on Yamato, but on Yamato it is very frequent, appear on our nightly build 80% of the time.
