CCC is an advanced backup and file copying utility for the Mac.

System Requirements

  • macOS 10.15 Catalina (10.15.7+)
  • macOS 11 Big Sur
  • macOS 12 Monterey
  • macOS 13 Ventura
  • macOS 14 Sonoma
  • CCC is a native application on both Intel and Apple Silicon Macs (i.e. a "Universal" application)

Older versions of CCC are still available for users running older OSes. Note that these older versions are not actively being developed and support is provided on a case-by-case basis.

Supported configurations

  • An APFS formatted volume is required for a backup of the macOS startup disk
  • SSDs and hard disk drives in Thunderbolt and USB 3.0+ enclosures — please see our list of recommended backup devices
  • CCC is supported only on Apple Macintoshes that officially support macOS Catalina (or higher)
  • A minimum screen resolution of 1024x768 is required

Configurations that are not supported

  • CCC will not back up to or from an unformatted or unmounted device — the source and destination must have a filesystem recognized by macOS and visible in the Finder
  • Copying Windows system files is not a supported configuration
  • CCC will not back up directly to optical media (e.g. CD-ROM or DVD-ROM)
  • WebDAV, FTP, NFS and other "cloud" destinations are not supported
  • CCC is not a two-way synchronization solution designed to keep two Macs in sync with each other — this is not a supported configuration.
  • Performing mass deployments with CCC is not supported. Apple discourages this sort of deployment and offers additional resources here, and there are alternative solutions to consider.
  • We can only support configurations of macOS that are supported by Apple on your hardware. For example, we cannot help you get Catalina running on a 2008 MacPro. Likewise, you cannot restore Mojave onto a 2019 MacBook Pro that shipped with Catalina. Hackintosh bootability issues should be pursued through a Hackintosh community forum. If Apple doesn't support it, we cannot support it.
  • CCC can copy virtual machine container files, but copying to or from a virtual machine is not supportable.
