But which installer did you use? Is your Python using Intel builds or native ARM builds?
I tested miniforge https://secure-web.cisco.com/1Z3CCsuE8ug-Zmk3Fqg9tPqSueXQwzQgAsJS-uaOScEsbeQm4mLYg8DzbhzUOWxKLGC5IbXPTHzxfk0-LUit9eML8-m0BRtwv8sZpEEra-6oZ-FtgQ5De_ccj7K3gFlAb8Hue7SsEHoYXtWqRW8SdLBuEKxHe_nKioTaOEm2zTVsV7KfGTkeQZam--O4arZoWlPN8WTMjaQc3DZ0C6QdUtiyjDfkV5CniuYbNqgxKPnwbzeIYpdTFsgzcWjhplfratjLHetK4YN4N9joZgy-kQw/https%3A%2F%2Fgithub.com%2Fconda-forge%2Fminiforge x86_64 and arm64 installers, the x86_64 allowed me using all dependencies of MNE, 3d viz included.
The arm64 supports the scipy stack & matplotlib out of the box.
