Hi @schwemro, thanks for reporting this back to us. I will have a look into your issue and get back to you.

There is a statically built version for Mac arm chips (macarm.zip) that should solve your issue.

https://github.com/MODFLOW-USGS/modflow6-nightly-build/releases

If this does not work, you will have to compile from source locally.
