dev branch reinstall on Mac fails

[Ezward]

I'm trying to reinstall on my Macbook Air (i5, so x86, not ARM) and did the steps to remove the conda donkey environment as per https://docs.donkeycar.com/guide/host_pc/setup_mac/

conda update -n base -c defaults conda
conda env remove -n donkey

Then tried to recreate the environment, but this fails;

[15:17:10] (base) Eds-MacBook-Air:donkeycar edmurphy$ conda env create -f install/envs/mac.yml

`$ /Users/edmurphy/miniconda3/bin/conda-env create -f install/envs/mac.yml`

  environment variables:
conda info could not be constructed.

[DocGarbanzo]

Looks like your miniconda base environment is somehow messed up. Can you re-install that? I would also recommend to run

conda install mamba
mamba env create -f install/envs/mac.yml

Because the env resolution in conda currently takes ages.
