Carbon Copy ClonerOverview

Carbon Copy Cloner backups are better than ordinary backups. Suppose the unthinkable happens while you're under deadline to finish a project: your Mac is unresponsive and all you hear is an ominous, repetitive clicking noise coming from its hard drive. With ordinary backups, you'd spend your day rushing out to a store to buy a new hard drive and then sit in front of your computer reinstalling the operating system and restoring data.

With Carbon Copy Cloner, your data and the operating system's data are all preserved on a bootable volume, ready for production at a moment's notice. When disaster strikes, simply boot from your backup and get back to using your Mac. At your convenience, replace the failed hard drive and then let CCC restore the OS, your data and your settings directly from the backup in one easy step.

Any backup application can save your stuff. A CCC bootable backup will save your productivity too!


  • Fixed This update is qualified on OS X El Capitan.
  • Fixed Fixed an issue that would lead CCC to report that its private keychain is not writable when the keychain had not yet been created.
  • Fixed CCC will no longer allow running another task as a postflight task if the secondary task is disabled.
  • Fixed SMTP usernames that contain special characters (e.g. "%") are now accommodated.
  • Changed The user agent is no longer re-launched after changing the Show CCC icon in menubar preference. Especially on OS X 10.11, application launch time can be slow and this delay could lead to scenarios in which the preference became out of sync (e.g. if the user were to change that setting very rapidly).
  • Fixed Addressed a regression in which CCC occasionally could not skip past unreadable files.
  • Changed Updated the procedure used to clone the Recovery HD volume to avoid an error at the end of the task that was specific to El Capitan.
  • Changed Fixed a UI anomally in which the task name field was difficult to edit when another task was running.
  • Changed Fixed an issue in which some UI elements in the Scheduler popover appeared to be disabled (but were not) on Yosemite and El Capitan.
  • Fixed Fixed an issue in which the "Submit Logs" button in CCC's Help window was inaccessible in non-English localizations.
  • Fixed Fixed a time zone adjustment issue for cases where a task was created in one time zone but then initially scheduled in another time zone.
  • Changed When CCC encounters multiple volumes with the same unique identifier, it now presents the names of those volumes when reporting the problem. This should make it easier to resolve this esoteric issue.
  • New Feature When disabling the SafetyNet, CCC now asks the user if he would like to delete the SafetyNet folder on the destination. This will help avoid some cases of the task failing due to the destination being full.
  • Fixed Fixed an issue specific to El Capitan in which debug output spewed by Apple's hdiutil utility would be interpreted as errors and cause a disk image creation or mount task to fail.
  • Changed Added custom VoiceOver descriptions for the task status images in the Task History window.
  • Changed Added a global exclude for the special hidden .Transporter Library folder. This proprietary device from Connected Data was causing backup tasks to stall due to a bug in the OSXFUSE code that supports that device.
  • Fixed Fixed an issue in which the reminder timer associated with an "On Reconnect" task wasn't getting removed when the task was switched to ad hoc.
  • Changed Added a workaround for fuse4x filesystems that don't advertise support for files larger than 4GB.
