On my side, I had the problem and look a little before installing manually or installing miniforge. The thing is that conda from miniconda or anaconda looks by default on osx-64 and noarch architecture and not osx-arm64 (which is the architecture on which the package has been made). So just parameterize your conda (in ~/.condarc for me) by adding those lines: subdirs:   - osx-arm64   - osx-64   - noarch If you want conda to go looking in osx-arm64 by default, change also the value of subdir and set it with osx-arm64 (same file): subdir: osx-arm64 Hope it helps.
