  • 将下载的两个文件(BaseSystem.dmgBaseSystem.chunklist)放入 com.apple.recovery.boot 目录下

  • 目录结构如下

├── EFI
│	├── BOOT
│	└── OC
└── com.apple.recovery.boot
 	├── BaseSystem.chunklist
 	└── BaseSystem.dmg
  • 准备一个1G以上的优盘,然后格式化

  • 将目录结构下的文件拷贝个优盘的根目录

注意,上面的目录结构最好不要保留其他文件,可能会有其他状况发生

  • 重启电脑,在启动选项里选择优盘中的OpenCore.efi启动即可

耳机🎧解决

进入 ComboJack 目录,执行 ComboJack_Installer/install.sh 文件即可。

其他说明

  • 安装macOS Big Sur的过程很漫长 , 请耐心等待 , 不一定是有错误
  • 每次升级或替换新的EFI后 , 最好重置一下NVRAM
