Bombich Software has released Carbon Copy Cloner 3.4.5, addressing a variety of issues. The popular donationware disk cloning and backup utility migrates entries in its private keychain to a new keychain that complies with the Gatekeeper security feature in OS X 10.8 Mountain Lion. Should a system dialog ask you to grant access to a keychain item, be sure to click Allow. The update also reverts to running a scheduled task automatically upon waking your Mac if the task’s run time occurred during sleep (which was built into the app in versions before 3.4.4). You can contact the Bombich Software Help Desk for guidance on a hidden setting that automatically skips tasks missed during sleep. Other fixes include more-consistent Growl notifications in 10.7 Lion, ensuring the last choice in the preset configurations menu is retained, and correctly rescheduling tasks configured to run weekly or monthly.
