Carbon Copy Cloner requires macOS. CCC will not run on Windows.
Carbon Copy Cloner 5 is the latest version available. Users running Yosemite (10.10), El Capitan (10.11), Sierra (10.12), High Sierra (10.13), or Mojave (10.14) should use this version of CCC. If you are having trouble downloading CCC from the link above, try this alternate download location.
Upgrading from CCC 4? CCC 5 is a paid upgrade. CCC 4 Personal and Household licenses purchased prior to May 22, 2017 are eligible for upgrade pricing. When you open CCC 5, it will automatically retrieve your new license or an upgrade coupon that you can use to purchase CCC 5 at 50% off. CCC 4 licenses purchased on or after May 22, 2017 are eligible for a free CCC 5 upgrade license.
Are you beta-testing Apple's new macOS 10.15 Catalina? Help us test CCC 5 against macOS Catalina by joining our beta program. Open CCC 5 on Catalina, and CCC should automatically prompt to install our latest beta.
Please choose Ask a Question from CCC's Help menu to let us know if you encounter any problems or have questions about support for new features of that OS.
Notes for macOS Catalina testers:
- The current build of CCC will not make a proper backup of a macOS Catalina startup disk. Don't attempt to back up the startup disk, and ignore any suggestions to reformat the destination as HFS+.
- Your Catalina startup disk will not appear in CCC's sidebar.
- If you would like to make a backup of your user data on a Catalina volume (not that you should be using it in production!), you may drag the /System/Volumes/Data folder onto CCC's Source selector to specify the Data volume as the source for a backup task.
- Third-party apps need pre-approval to see the content of external volumes on macOS Catalina. Choose "Grant Full Disk Access to CCC" from the Carbon Copy Cloner menu to take care of that.
- Stay tuned for another beta release that will address most of the "backing up the Catalina startup disk" issues.
- No, we don't have a timeline. The changes in Catalina that affect backup processes are more significant than any previous macOS release. CCC can make a bootable backup of Catalina (we had a proof of concept just days after Apple's announcement), and we will be ready for Catalina before it is released in the Fall. We will post another beta when we have addressed the bulk of the known issues. It's a long list, we appreciate your patience!
Carbon Copy Cloner 4.1.24 is compatible with Mountain Lion (10.8), Mavericks (10.9), Yosemite (10.10), El Capitan(10.11), Sierra (10.12) and High Sierra (10.13). Note that while this version of CCC will work on El Capitan and newer OSes, we recommend that El Capitan+ users upgrade to CCC 5. We offer technical support for CCC 4, but we are no longer actively developing it. If you are having trouble downloading CCC from the link above, try this alternate download location.
CCC 4 and Mojave: CCC 4 is qualified up to macOS High Sierra. CCC 4 license holders are welcome to continue using CCC 4 on later OSes with the understanding that this is an untested and unsupported configuration. CCC 5 is fully qualified on macOS Mojave and offers extensive support for APFS, including support for point-in-time restores via APFS filesystem snapshots.
