0x00 What's Happend?
我的 MacBookAir 在升级到Catalina 之后，经常在休眠模式重启，随后在桌面上显示“因为意外而重新启动”的信息，以下是跟随日志：

最后通过禁用了日志中显示的 “AppleUSBCardReaderInterfaceNub” 相关 kext，解决了这个问题。
以下是解决步骤：
1、下载 Kext Wizard.app
2、搜索 AppleUSBCardReader
3、Unload
选中它，点击 Unload
注意：在 macOS 重新启动后，这个内核扩展会被重新加载，如果你需要重启之后不被加载，可以直接删除这个 .kext ，但我不建议这么做。
