Title: [TASK] Run devserver with elevated permissions on Mac

Apparently the devserver needs to be run with elevated permissions on os x, possibly on linux as well.

I assume it would work to run the grunt task with sudo, but I offer this as an alternative. I'm not sure what is preferable on a Mac - this, or indicating in the documentation that the task should be run with elevated permissions.
