Bombich Software has released Carbon Copy Cloner v4. It sports a completely revamped user interface that is more intuitive, and includes new features like: the ability to chain tasks together (one kicks off with another finishes), more email alerts and confirmation options, and once an Administrator user authenticates they won’t be asked to authenticate again in the future.

CCC v4 can be individually licensed for $39.99 per computer, or “pro” licensed for $100 per engineer (temporarily technical support use on an unlimited number of computers). CCC v3.5 license holders qualify for a 50% off discount, and v3.5 licenses purchased after June 2, 2014 qualify for a free v4 license.
