Setting User Mask

By default, files created on Mac OS X in directories that can be accessed and written by everyone are created with permissions that allow for the owner to write to the file, but for other users to only read the file. This can be a problem as files created by Harmony inside the database directories that are shared over your network need to be accessible and writable by all your project collaborators.

A quick way to remedy this is to configure your machine to have a permissive user file creation mask (or umask).
