Compatible with Tiger and Leopard

Users running Mac OS X 10.4 or 10.5 should use CCC 3.4.7. Note that while this version of CCC will work on Snow Leopard and Lion, it is not actively qualified for use on these OSes. We will continue to offer limited support for 3.4.7 on a case-by-case basis, but we are no longer actively developing this version.

CCC and Yosemite

Carbon Copy Cloner 3.4.7 and 3.5.5 are not supported on Yosemite.

When Yosemite is available on the Mac App Store, we will offer a version of CCC that is qualified on that OS. If we have a beta version of CCC available for testing on Yosemite before that time, we will make that information available here.
