1. "Error: failed to connect to [localhost:27017]"

MongDB isn't running, please run it before you run grunt...
Consider MongoDB a program that needs to be running before you can run grunt on your MEAN project.
Follow these instructions here for mongodb installation:
http://docs.mongodb.org/manual/tutorial/install-mongodb-on-os-x/ Manual Installation is the only manner I could get things working

I also needed to be in /usr/local/bin before I could fire mongod Once mongod is running in your terminal window, open a different terminal window and cd to the directory where your MEAN project is located.

There you can run a grunt command and avoid the dreaded warning: [nodemon] app crashed - waiting for file changes before starting...

At that point, you can navigate to http://localhost:3000

Mcferren thanks for the explenation
