## 创建启动U盘
|
|
|
|
|
|
|
|
|
|
|
|
### U盘格式化
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
### 刻录U盘
|
|
|
|
|
|
|
|
|
|
|
|
[下载插件](https://codeload.github.com/barrykn/big-sur-micropatcher/zip/main)
|
|
|
|
|
|
|
|
|
|
|
|
[项目的GitHub](https://github.com/barrykn/big-sur-micropatcher)
|
|
|
|
|
|
|
|
|
|
|
|
打开终端
|
|
|
|
|
|
|
|
|
|
|
|
``` bash BASH
|
|
|
|
|
|
sudo /Applications/Install\ macOS\ Big\ Sur.app/Contents/Resources/createinstallmedia --volume /Volumes/upan
|
2021-06-09 03:21:00 +00:00
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
将下载好的 big-sur-micropatcher 解压并进入到目录
|
|
|
|
|
|
|
|
|
|
|
|
``` bash BASH
|
|
|
|
|
|
sudo bash micropatcher.sh /Volumes/Install\ macOS\ Big\ Sur
|
|
|
|
|
|
sudo bash install-setvars.sh /Volumes/Install\ macOS\ Big\ Sur
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
## 安装
|
|
|
|
|
|
|
|
|
|
|
|
开机，并按住 option 键。在 SSD 硬盘基础上此时会出现两个图标
|
|
|
|
|
|
|
|
|
|
|
|
会出现黑屏，并且自动关机。此时重新启动电脑并按住 option 键，进入 Install macOS Big Sur 并按照常规进行安装。
|
|
|
|
|
|
|
|
|
|
|
|
## 修复
|
|
|
|
|
|
|
|
|
|
|
|
安装完成之后，进入桌面可能会出现无法识别网络的情况，除非使用的是 Late 2013 iMac 或者更换了 802.11ac 网卡的机型，现在已经可以正常使用。
|
|
|
|
|
|
|
|
|
|
|
|
如果无线网卡无法正常识别工作，打开终端
|
|
|
|
|
|
``` bash BASH
|
|
|
|
|
|
sudo sh /Volumes/Install\ macOS\ Big\ Sur/patch-kexts.sh
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
重新启动无线网卡就正常了。
