Compatibility and support for CCC v5 on Monterey and newer OSes
CCC v5 license holders are welcome to continue using CCC v5 on OSes beyond macOS Big Sur; there aren't any limitations placed upon CCC v5 that would prevent it from continuing to work as Apple issues new OS releases. However, CCC v5 development ceased when CCC v6 was released in May 2021. We will continue to offer technical support for CCC 5, but we are no longer actively developing it, nor testing it against newer OSes.
