You the real MVP!

Though I'm getting this error on an Intel macbook (Monterey); it works fine on a Windows11 box:

I had the same issue and then noticed that I need git lfs - otherwise just cloning the repo will not download the weights.

After getting the model with git lfs I get:

Thanks for the tip! After running `brew install git-lfs && git lfs install` on my Macbook, I was able to run the model.

I get the same error on an M series MacBook (Ventura). However from the repo README.md it looks like make should work instead of cmake, I’ll give that a try.
