Opis

Signed System Volume is a security feature introduced in macOS 11.0 Big Sur. During system installation, a SHA-256 cryptographic hash is calculated for all immutable system files and stored in a Merkle tree which itself is hashed as the Seal. Both are stored in the metadata of the snapshot created of the System volume. The seal is verified by the boot loader at startup.
