![]() The operating system now resides on a cryptographically sealed "Signed System Volume" that can only be copied by an Apple-proprietary utility, "Apple Software Restore" (ASR). Big Sur's Big ChangeĪll on its own, Big Sur introduced a significant new change to the creation of an external boot device. Big Sur and the new Apple Silicon Macs have shaken up the way Mac users will recover from hardware failure. When Apple made it more complicated with Mac OS X, we pioneered the "bootable backup" solution (nearly 20 years ago!), and this has been a feature we've reliably supported on every new Mac and every new OS since then.īut Apple has never been afraid of shaking things up to blaze new trails. Prior to Mac OS X, people could simply drag and drop the System folder from one volume to another presto, external boot volume. CCC can do so much more than just make copies of the system, and now is the right time to revisit your backup strategy and make it even better with some of the new features in CCC 6.įor decades, Mac users have taken for granted the Mac's "External Boot" feature. A bootable external device may not be a part of that strategy. CCC 5.1.27 and CCC 6 can make bootable copies of the system on Intel and Apple Silicon Macs (11.3+) right now, and we'll continue to support that functionality as long as macOS supports it.īut as Apple's platform continues to evolve, we have to design our recovery strategies around the current hardware capabilities.
