 This script cuts through all that by scripts running on your Mac and displaying on your screen.
 
 You will benefit most from this if you configure a <strong>new</strong> laptop for yourself or for other developers joining your organization. You'll skip wasted days installing everything one at a time (and doing it differently than colleagues).
