Jupyter Notebook fails on M1 MACOS

I have successfully installed Anaconda on a brand new MacBookPro equiped with the M1 chip. Spyder works perfectly. When I launch Jupyter Notebook, it initializes well, i.e. both Terminal window opens and indicates what seems to correspond to ‘ok’, and the Jupyter page on Firefox opens fine too.
But since I click on ‘New Python3 (ipykernel)’ or try to open an existing .ipynb, than the new page just contains a big ‘500 : Internal Server Error’
thanks in advance

Same problem with my M1 macbook air.
the notebook is trying to connect to kernel and then I receive the message:
“A connection to the notebook server could not be established. The notebook will continue trying to reconnect. Check your network connection or notebook server configuration.”
Any help on how to check notebook server configuration is welcome.

Which version did you install? I’m assuming the x86 version - as we haven’t released a new Anaconda Distribution M1 installer yet. So that means it is running in emulation. You may want to try installing the M1 native Miniconda installer (https://repo.anaconda.com/miniconda/Miniconda3-latest-MacOSX-arm64.sh) - and then installing the other packages you need (macOS M1 pkgs currently available: main/osx-arm64). The next Anaconda Distribution installer will offer an M1 native option (coming soon).

Thank you for your answer. I discovered that contrary to Notebook, Jupyther Lab works perfectly. For me this is equivalent; I simply moved to Lab. Maybe I’ll try one next day to follow your advice, but for now, I don’t need more that Jupyther Lab. Thanks again
