配置Alienware 17 r4
雷电3:8086, 15DA,Intel JHL6340 Thunderbolt 3 Bridge (C step) [Alpine Ridge 2C 2016]

原先没有任何修改时，开机前插着雷电启动，可以使用雷电设备，但是不能热拔插，睡醒回来也会挂。。。
后来发现@the-darkvoid写了macOS-IOElectrify这个KEXT，拿来试试终于可以热拔插了，感谢作者！！！

屏幕快照 2017-11-19 上午10.13.01.png

貌似把雷电仿冒成了express card所以thunderbolt下无显示。。
同机型可直接使用前往https://github.com/RockJesus/macOS-IOElectrify

待解决问题：开机必须插着雷电启动才能使用，睡醒后雷电口依旧会挂，重新拔插也不行

日志里一直循环这些，求大神帮助解决！!

xps或者其他机型参考作者的https://github.com/the-darkvoid/macOS-IOElectrify
1.自行修改ssdt内雷电路径
举例:Scope (_SB.PCI0.PEG2.PEGP)
Scope (_SB.PCI0.RP05.PXSX)
2.（可选不确定作用）IOElectrify.kext/info.plist里添加你的雷电bridge id ，删除所有#
举例：IOPCIPrimaryMatch 0x76158086空格0x15da8086空格你的id
