问题 + 背景
我在 2015 年的 MacBook Pro 15" 上安装了双启动的 Ubuntu 18.04。我尝试使用磁盘实用程序删除 Ubuntu 分区,但失败了(“内部错误”)。重启后,我看到的唯一启动选项(按住 Option 键)是 EFI 启动。我可以启动 Ubuntu,但 macOS 不可用。我想恢复启动 macOS 的能力。
我尝试过的事情
- SMC 和 NVRAM 重置:无影响
- 互联网恢复:当它提示我选择用于安装的磁盘时,它显示没有磁盘
- 磁盘实用程序急救:内部磁盘的健康检查通过
- Thunderbolt 磁盘目标模式:进入磁盘模式,但不会显示在连接的其他笔记本电脑上
