For Ubuntu, not Mac, but I maintain a set of 3 shell scripts over at https://github.com/hiAndrewQuinn/shell-bling-ubuntu that put 95% of everything I use on an everyday basis.

I picked shell scripts specifically because I didn't want the overhead of installing eg Ansible, even if its idempotency would be nice. I definitely like Ansible for DevOps on virtual machines, though, it's a solid platform.
