CCC is an advanced backup and file copying utility for the Mac.
System Requirements
- macOS 13 Ventura
- macOS 14 Sonoma
- macOS 15 Sequoia
- 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 Ventura (or higher)
- A minimum screen resolution of 1024x768 is required.
Configurations that are not supported
- Backing up to or from an unformatted or unmounted device — the source and destination must have a filesystem supported by macOS and visible in the Finder.
- Copying Windows system files
- Backing up directly to optical media (e.g. CD-ROM or DVD-ROM).
- Backing to WebDAV, FTP, NFS and other "cloud" destinations.
- CCC is not a two-way synchronization solution designed to keep two Macs in sync with each other.
- Mass deployment – Apple discourages this sort of deployment and offers additional resources here, and there are alternative solutions to consider.
- While CCC can produce bootable copies of macOS via the Legacy Bootable Copy Assistant, this functionality is not recommended nor supported as part of a backup strategy. In general, Apple designs macOS to be installed, not restored nor copied.
- CCC can copy virtual machine container files, but copying to or from a virtual machine is not supportable.
