如何修復grub來啟動Mac OS X Yosemite？

[英]How to fix grub to boot Mac OS X Yosemite?

 原文  2014-10-18 19:08:06  2   2    macos/ ubuntu/ boot

問題描述

我根據此鏈接https://stackoverflow.com/questions/25000934/trouble-with-dual-boot-ubuntu-after-update-mac-os-yosemite/26433930#26433930更改了Macbook上的啟動順序。

但是...現在我在啟動Mac OS X Yosemite時遇到問題。 我收到錯誤消息：未找到錯誤文件'/ mach_kernel'。 等如何解決？

提前致謝！

PS：可能不是grub.cfg中的問題

這是grub.cfg：

2 個解決方案

這可能不是很有用，但是在加電時按住Option（或Alt）通常會為您提供Apple自己的啟動管理器，您應該可以啟動到Yosemite。

然后，你可以使用重新安裝rEFInd ./install.sh --alldrivers安裝（如描述在這里 ），或正式rEFInd准則（發現在這里我也用來執行全新安裝，或者作為一個鏈接上一個答案） Ubuntu，雙引導正常工作。

我同意在啟動時按住Option鍵。 但是，我發現，如果在啟動時按住Command + Option + R + P，等待兩個“叮”聲並重新啟動，它將自動啟動到您使用的任何Mac系統中。 我有MacOS 10.12.4，現在可以正常使用了。

另外，如果使用選項鍵啟動，則可以進入系統偏好設置->“啟動盤”並選擇您的操作系統，它將直接啟動進入該系統。
