  有个老哥是重新插拔了 io board 解决的（只针对老机器）

  Luckily, I came across a strange but working temporary fix using a windows bootcamp installation posted by Milangoa in this thread:

  https://www.reddit.com/r/MacOSBeta/comments/jk72ki/black_screen_while_upgrading_to_bigsur_1101_beta/

  The official Big Sur Update went without any problems on my Mid2014 13″ MacBook Pro. However, when turning the machine off yesterday I was not able to start it and encountered the black screen just after turning it on. I was able to start the machine by unplugging the i/o board, then I held the option key and the bootcamp boot options appeared, however the WiFi option was not shown. I hot plugged the i/o board and booted into my Windows 10 installation which resides on an external USB drive. At first boot WiFI did not work but the USB port on the i/o board and bluetooth worked without a problem. Then I restarted the machine again straight into bootcamp and on the boot options page the WiFi option was already shown and then also worked in Windows. After that I restarted again and booted up Mac OS Big Sur and everything just works like before. Waking up from sleep mode and rebooting seems to work fine for now. What does not seem to work is to shut the machine down, because afterwards its again just showing the black screen.

  原帖说拔下 IO 板升级到 11.1 然后重新插上 IO 板解决了问题，主试过了么？

  @bibi012 看完漫画，这是个悲伤的故事，这韩国老哥也真心 NB，在店铺当场摔 MacBook 。
  当维修费用和二手本子价格差不多的时候，就失去了维修的理由。

  @huamiao 我的是 19 年的机器，没办法插拔，13 ～ 14 年机器可以

• 主 資深大佬 : bibi012

  @3dwelcome 是的，我去跟他们理论时候，如果不是穷，我也会摔机器

  反正不能保修了，试试第三方呗，也许是小问题，大不了赌个南桥干个 EC 啥的

• 主 資深大佬 : bibi012

  @tianyu1234 我买了螺丝刀，准备拆开来看看，插拔下插口，不行我就快递给 B 站的维修撕。铁定不会花 4000 块钱换主板

  所以 apple 逼着你买 ac+

  @SandyLee 感觉很多现代社会的机器质量都不如 7 年前的，我昨天开机 note3 （当年的旗舰机） 丝滑顺畅

  15 款是真的皮实。 我也是 15 款低配，从来没出过问题… M1 的 MBP 买来用了一个礼拜就出现莫名其妙的软件加载卡顿，换货了…

  @007yxc 我记得我免费换过一次屏幕，自己换过触摸板的排线（也是他们家的质量问题） 真是操蛋的苹果
