以后的 macOS 会不会也开始采用 ios 的机制，开启联网验证安装呢？还有就是这个 mac 。。。会不会像 ios 一样出现可以越狱的情况。。。

封闭和构架没关系的，想做的话，T2 芯片就能做了。

Mac 为啥需要越狱…架构和开放与否也没啥关系吧

官方文档说，关闭 sip 可以安装其他操作系统了。
比如 arm 版的 linux，不过没法给 SOC 写驱动，m1 的那么多专用电路就浪费了 |

> So, what are the security modes? In full security mode, new Apple Silicon Macs enjoy the same best-in-class security technologies that exist on iPhone. This mode is enabled by default. In addition, you can now boot from external disk without downgrading the security of the system. We think this is great.
> By contrast, reduced security provides flexibility and configurability of your Mac, and it keeps the Mac what it is. Reduced security allows you to run any version of macOS, including the versions that are no longer signed by Apple. > In addition, users that want to install notarized kernel extensions must enable this mode in order to do so. > To enable reduced security, users must authenticate in macOS Recovery first. <https://developer.apple.com/videos/play/wwdc2020/10686/?time=1078> |

也就是以后需要手动调低安全级别到 reduced security 才可以安装旧版 macOS （早于 Big Sur 的 macOS 是肯定跑不起来啦）以及使用内核插件，但不是完全不可能。

mac 越狱？
mac 本身就开放了 root 权限啊没必要啊，至于 lz 担心的收紧权限就是杞人忧天了，mac 作为一个 pc 的操作系统，不给用户管理员权限修改系统，一堆工具怎么用 |
