In my new MAC M1. 1)I installed the Minoforge3 (bash Miniforge3-MacOSX-arm64.sh) 2 Initialized a conda base environment (conda init) 3) Installed numpy properly: conda install numpy "libblas=*=*accelerate" And then the suggested benchmark runs in 1.07172 secs

I had exactly the issue. I downgraded to conda install -c apple tensorflow-deps==2.9.0 python -m pip install tensorflow-macos==2.9.0 python -m pip install tensorflow-metal==0.5.0 with Python==3.18.6, and works great in my new MAC M1 MAX! Hope it works for you.
