Well then you aren't using the GPU. Only CPU Tensorflow. :P Ofcourse it gets rid of the error.

Update: with tensorflow-metal version 0.1.1 that warning also vanishes. Hopefully this will be fixed in coming versions of metal.

Another Update: Metel v0.2.0 is built for MacOS 12 Monteray. So that version should work fine after updating to Monterey as reported by others.

**Does anyone know how to roll back to 12.0.1 without losing my data? **
