On ARM Macs, importing snowflake-connector-python logs Failed to import ArrowResult. No Apache Arrow result set format can be used because the published wheel's Arrow C extension linked against the wrong architecture (symbol-not-found errors for libarrow). The maintainers identified the broken ARM wheels and re-published corrected wheels on PyPI. Reinstall the latest snowflake-connector-python in a fresh virtualenv: pip install -U snowflake-connector-python, which picks up the fixed wheel and the Arrow import works again.
