niming007zh2 说了降级的。Howard 也就是第一篇的说法是“Apple silicon Macs can readily be reverted to older firmware and macOS, though, by putting them into DFU mode and restoring that older version of macOS complete with its firmware in the appropriate IPSW image.”;第二篇是 asahi linux (就是在 AS Mac 上成功逆向工程原生运行 Linux 的著名计划)的官方文档更是非常明确地说了:“A DFU Restore will completely wipe all data on the internal storage and restore the machine to factory condition. It is also the only way to downgrade System Firmware to a prior version.“
