MacOS make is outdated (or not GNU flavor not sure) and, for example, doesn’t support parallel tasks by default or some more advanced recipes.
Asking people to use gmake on a standard Makefile is much more difficult than just asking to install Justfile runner.

On my macOS laptop
which make
# /usr/bin/make
/usr/bin/make --version
# GNU Make 3.81
I haven't verified this. I've checked `make --help` using the built-in make on my Mac (GNU Make 3.81), it mentions the `--jobs` option to run multiple jobs in parallel.
Cannot provide precise issues with (as it was more then a year) but I encountered 3-4 problems after having complete Makefile which was kind of downer because I had to rewrite it to support “vanilla” make.
In the end I dropped parallel went with Justfile and it took fraction of time (but truth be told I had dynamic PHONY targets which aren’t super easy to setup in Make).
