I was personally just installing coreutils from homebrew, which contains nproc:

❯ nproc --ignore 2
8
❯ uname -s
Darwin

Which comes from:
https://formulae.brew.sh/formula/coreutils
https://github.com/coreutils/coreutils/blob/037b93106155c5e11681837305b541808fbdb9b5/src/nproc.c

The bigger Mac related concern for me with this repo was that bindata seemingly didn't work in pre-commit. Whenever I run pre-commit run --all-files on my Mac, it would change all the files and remove a bunch of things that seemingly shouldn't be removed.

If I just checkout main right now, and run make bindata this is all of the stuff that gets changed:
