Installation under Mac fails due to unsolvable conda dependencies

I run into this bc/ I wanted to try something on my mac :)

conda env create -n sonar -f covsonar/sonar.env.yml

Collecting package metadata (repodata.json): done
Solving environment: failed

ResolvePackageNotFound:
  - libstdcxx-ng=9.3.0
  - libgfortran-ng=9.3.0
  - _openmp_mutex=4.5
  - libgomp=9.3.0
  - libgcc-ng=9.3.0

I removed these dependencies from the env file and then installation worked. Additionally, I don't think that all of these lib dependencies are really necessary and thus the environment file could be cleaned to the really necessary dependencies (emboss, biopy, ...)?
