我是否应该重新安装所有内容,我有点想回到 Mac OS,我已经备份了所有内容?
编辑 System Bootorder not found, initializing defaults
每次我重新启动时,我都会在黑屏上看到此消息,然后它启动到 Linux,当我没有删除安装磁盘时,我会看到相同的消息。
按下选项按钮重新启动只会提供 EFIBoot 选项(无 MacOS)
笔记:我可以从磁盘实用程序中删除 Ubuntu,这是否有帮助?
首先我按照这些说明创建一个可启动磁盘并启动到 ubuntu。 https://ubuntu.com/tutorials/tutorial-create-a-usb-stick-on-ubuntu#1-overview
当安装结束时它要求我移除 USB 记忆棒时,我确实遇到了一点小问题,并且遇到了一些错误,但我重新启动后它又恢复了安装进度(不确定这是否导致了错误)。
我按下选项按钮重新启动我的 Mac,但它总是启动到 Ubuntu。
以下是一些输出sudo efibootmgr -v
