Change Description

MacOS on ARM will not run unsigned code. Our generated nightly and test compilations are unrunnable on it for others.

This script, run inside the app directory will sign the app and make it runnable. It also prompts the user and walks them through first and one time only cert creation.

Works for both TB and MB
