引导期间macOS Sierra / usr / libexec / lsd崩溃，系统无法启动

安装系统更新后，我的Mac mini根本无法启动，或者也许只有在停留在启动屏幕上几个小时后才能启动。

我在/var/log/system.log中找到了以下内容（重复很多时间）：

有人知道如何解决此问题吗？

大海捞针-但您可以尝试将“ / private / var / db / lsd /”目录重命名为其他目录，并查看它是否可以在下次重新启动时重建文件而不会出错。

@jksoegaard我的系统上没有这样的目录

您是否找到/ private / var / db目录？-也就是说，您到底错过了哪一部分？

— jksoegaard，2016年

我找到了@jksoegaard，/private/var/db但是那里没有lsd目录。我想我会删除此问题，因为我已经擦除了整个磁盘，现在重新安装系统。无论如何，谢谢您的帮助！
