I can replicate a apfs volume group that includes signed system volume and data volume, but a seal of replicated volume was broken and macos cannot boot from the volume. Especially, a hash of metadata is called "seal", and we can see that via diskutil command. It has cryptography hashes of data and metadata in filesystem. ![]() ![]() My understanding is that Big sur introduces Signed System Volume. Is there correct way to replicate the bootable big sur apfs volumes.
