CARBON COPY CLONER BOOTABLE SOFTWARE
You either have to erase the drive and copy everything again, or boot with the external startup volume and perform a software update within an active Big Sur session.

Apple offers a bypass that Carbon Copy Cloner has managed to take advantage of, which is a low-level copying tool called asr that can in some (but not all) circumstances copy Big Sur’s system volume from an internal to an external drive and keep it in bootable shape. Any change to even a single bit in the volume causes validation to fail (breaking the “seal”). Big Sur picked up on the system/Data volume division of Catalina, but added another layer: when installed or upgraded, macOS’s system volume has a cryptographic wrapper around it that prevents the slighest modification without detection.Įssentially, a Big Sur system volume has to be installed on a freshly erased disk, because the process of making the seal is unique to each volume. (The Big Sur volume isn’t even mounted directly, but as a read-only APFS snapshot, making it even harder for an attacker to find a way in.)īig Sur took that one step further in a way that affects your ability to continue to make backups of the style you might be accustomed to, and which requires a rethink for the present and future.

The system volume is read-only and locked against modification during an active macOS session the Data volume can be read and written, and apps on its may be launched. With the concept of a volume group in APFS, Catalina organized all system files and core apps into one volume and all user-owned and user-modifiable data, third-party apps, and some Apple apps into another. At your convenience, replace the failed hard drive and then let CCC restore the OS, your data and your settings directly from the backup in one easy step.Īny backup application can save your stuff.This culminated in macOS 10.15 Catalina in splitting macOS into two pieces, which appear seamlessly as a single unit in the Finder, but which severed a long-time intermingling of files. When disaster strikes, simply boot from your backup and get back to using your Mac. With Carbon Copy Cloner, your data and the operating system’s data are all preserved on a bootable volume, ready for production at a moment’s notice.

With ordinary backups, you’d spend your day rushing out to a store to buy a new hard drive and then sit in front of your computer reinstalling the operating system and restoring data. Suppose the unthinkable happens while you’re under deadline to finish a project: your Mac is unresponsive and all you hear is an ominous, repetitive clicking noise coming from its hard drive. Carbon Copy Cloner backups are better than ordinary backups.
