Snowflake Connector for Python Required on Apple Silicon Mac

[minus34]

Not sure if this affects Windows users as well (unable to test).

I got the error below trying to load the plugin in QGIS 3.40.1 on my M2 MacBook (running macOS 14.7.1).

The workaround was to manually install the Snowflake Connector for Python in the QGIS Python env using:

/Applications/QGIS.app/Contents/MacOS/bin/python3.9 -m pip install snowflake-connector-python

@minus34 what Connector Plugin version do you use?

[minus34]

That would help - 0.9.0
