To clone your Mac, the easiest way is to get yourself a spacious external drive and use an app such as Carbon Copy Cloner (my favorite) or SuperDuper!. As such, we havent released a Beta, or even an internal Alpha, because it. At present, its not possible to make bootable copies of Big Sur, even with asr, Apples own built-in replication utility. I found that it in Catalina (and Monterey & Big Sur) SD can 1) create a bootable drive. It also allows software updates to complete in the background while you work, which reduces the time it takes for your Mac to restart and complete updates. I havent said anything about Big Sur yet, and since the public beta has been out for a while, and Im getting more questions about it, its time. Download the latest version of SuperDuper for Mac for free. This advanced system volume technology provides a high level of security against malicious software and tampering with the operating system. All system files are protected on the signed system volume (SSV). MacOS includes enhanced protection for your Mac with cryptographic technology (macOS 11 or later) that prevents access to or execution of files that don’t have a valid cryptographic signature from Apple. So what’s a signed system volume? Here’s Apple’s explanation: However, the cloning process has become more difficult because of the “signed system volume” in macOS Big Sur and later, including macOS Ventura. But cloning is also handy for backing up your data. This is great for moving data from one Mac to another. In another word, a cloned hard drive is an exact copy of the original, including the operating system and all the files it needs to boot up and run. This includes the data allowing you to boot your system right from that copy. When you clone your Mac’s hard drive you create a bit-by-bit, duplicate of it. For example, I often do this to test in-beta versions of macOS. Right now, ASR will only copy whole volume groups (System and Data) we cant choose to copy just the System volume. That volume can only be copied using Apples proprietary APFS replication utility ('ASR'). Sometimes it’s helpful to create a bootable clone of your Mac, such as for testing software or implementing system changes. Starting in macOS Big Sur, the system now resides on a cryptographically sealed 'Signed System Volume'.
