What did come as a surprise, however, was a very subtle logistical change noted in a Product Security document published in February regarding the new Apple Silicon Macs. If you were making your backups bootable in case of hardware failure, then that's an extra logistical chore that you can now retire from your backup strategy.

An Apple Silicon Mac won't boot if the internal storage has failed Especially since the introduction of APFS, Apple has been moving towards a lockdown of macOS system files, sacrificing some convenience for increased security. Many of us in the Mac community could see that this was the direction Apple was moving, and now we finally have confirmation. They indicated that they were working to resolve the ASR/Apple Fabric issue, but they made it very clear that copying macOS system files was not something that would be supportable in the future. Apple partially resolved that in macOS 11.3, but even now using ASR to clone the system back to the internal storage of these Macs doesn't quite work – it causes a kernel panic.īack in December I had a conference call with Apple about the reliability and functionality of ASR on macOS and regarding Apple Silicon Macs in particular.
The "Apple Fabric" storage in these Macs offers per-file encryption keys (like the storage in iOS devices), and for months, ASR didn't work with it. When Apple introduced Apple Silicon Macs, we discovered another snag.

Apple Software Restore isn't quite ready for the new Apple Silicon Mac storage So, while we're certainly able to make a bootable copy of the system with ASR, it starts to feel like using it causes us to lose sight of what's actually important to back up – your irreplaceable data. we cannot copy the system and retain versioned backups of your data, we can't evaluate what was copied, we can't exclude items from the initial backup, we can't save checksum data for later verification. ASR is also very one-dimensional choosing to copy the system requires that we sacrifice other backup features, e.g. There are many scenarios where ASR simply fails with no explanation. We've performed tens of thousands of ASR clones at this point, and we've discovered that ASR is just not as robust as our own file copier. We were already familiar with ASR, so fairly quickly we were making bootable backups of Big Sur back in November. 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 backups 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.
