找另外一台有 TB3 的苹果电脑 然后重刷 T2: https://mrmacintosh.com/how-to-restore-bridgeos-on-a-t2-mac-how-to-put-a-mac-into-dfu-mode/
记住是 Revive,不是 Restore 。如果 Revive 不行那你就需要清空数据 Restore 了 |

tdwyx OP @CupTools 谢谢, 非常感谢! 我把电脑带办公室来了, 一会儿借同事的机器试试. 能恢复数据就最好了, 很多东西还没备份

tdwyx OP @CupTools 试了几次都没成功, 在 Installing OS 的失败, 每次报的错还都不太一样 .....
准备预约 genius bar 了 PS: 试了下使用 USB Type A 转 Type C 的线也能进入到 DFU mode |

@tdwyx 我的恢复好了。我只是下载了更新都没安装,关机以后,再开机就变砖了。弄的我都不敢更新了,幸好找到上面的方法解决了。刚才联系授权维修点直接就说这种要换主板。。。

刚遇到了,真实情况是,macmini 自动关机了,灯也黑掉,
这时候不要开关机,等几分钟,它居然自动开机并更新完毕了 🌚 简直是神操作 |

tdwyx OP https://eclecticlight.co/2019/11/13/why-do-macs-with-t2-chips-display-a-black-screen-so-long/
This situation is even more critical when the firmware of the T2 chip is to be updated. This involves downloading it direct from Apple, checking it, and its installation. During much of this period in the update, the Intel side has to be shut down, providing the user with just a black screen to gaze at. |
