我根据此链接https://stackoverflow.com/questions/25000934/trouble-with-dual-boot-ubuntu-after-update-mac-os-yosemite/26433930#26433930更改了我的macbook上的启动顺序。
但是......现在我在启动Mac OS X Yosemite方面遇到了问题。我有错误消息：错误文件＆＃39; / mach_kernel＆＃39;未找到。等如何解决？
提前致谢！
P.S。：可能不是grub.cfg中的问题
这是grub.cfg：

这可能不是很有帮助，但是在启动时按住Option（或Alt）通常会给你Apple自己的启动管理器，你应该可以启动Yosemite。
然后您可以使用./install.sh --alldrivers安装（如here所述）或官方rEFInd指南（找到here，或作为上一个链接的答案）重新安装rEFInd还习惯于执行Ubuntu的全新安装，双启动工作正常。

我同意在您启动时按住选项键。但是，我发现如果你在启动时按住命令+选项+ r + p，等待两个＆＃34; ding＆＃34; s并重新启动，它会自动启动到你正在使用的任何Mac系统。我有MacOS 10.12.4，现在工作正常。
此外，如果您使用选项键启动，您可以进入系统优先级 - >启动磁盘并选择您的操作系统，它将直接启动它。
