![Mac 无法启动到安全模式](https://linux22.com/image/1326835/Mac%20%E6%97%A0%E6%B3%95%E5%90%AF%E5%8A%A8%E5%88%B0%E5%AE%89%E5%85%A8%E6%A8%A1%E5%BC%8F.png)
除安全模式外,Mac 可以正常启动。
启动时按住 Shift 键,我可以看到灰色屏幕上的进度条。在 Mac 重新启动之前,进度条大约移动到一半。
我修改了 nvram boot-args 以获得更好的外观:
sudo nvram boot-args="-x -v"
它肯定会通过 fsck,跳过加载内核扩展(因为它处于安全模式),对网络接口执行某些操作,然后这是它最后要清除的东西......

答案1
无法启动到安全模式可能是因为系统配置了加密或其他安全设置,导致无法启动到此类模式,也可能是因为无线键盘将启动参数传递给系统的方式存在细微差别,或者是因为文件系统存在错误。

尝试访问您的恢复分区。启动时按住 Apple 键 (Command)(在听到苹果铃声之前)。访问恢复分区后,单击“实用程序”菜单(顶部)中的“磁盘实用程序”。在磁盘实用程序中单击您的 Macintosh HD 并修复磁盘权限。
您需要从恢复分区(而不是通常启动的 Mac)执行此操作,因为您的权限可能已损坏。
