驱动情况
- GTX650 显卡免驱
- 网卡沿用之前的
RealtekRTL8111.kext，进系统已驱动好 - 声卡需要重新驱动。由于 Apple SIP/Rootless安全技术，也无法使用之前的替换
AppleHDA.kext+HDAEnablexxx.kext驱动，所以接下来详细说说声卡新的驱动方式。
声卡驱动方式
GitHub项目：toleda/audio_CloverALC OS X Realtek ALC onboard audio with Clover
若使用了任何修改版的 AppleHDA.kext，请先替换回原版。
如无意外，在 EFI 分区 /clover/kexts/10.11/ 生成了 realtekALC.kext，重启生效。
CPU变频
GitHub 项目：Piker-Alpha/ssdtPRGen.sh
curl -o ~/ssdtPRGen.sh https://raw.githubusercontent.com/Piker-Alpha/ssdtPRGen.sh/master/ssdtPRGen.sh
生成的 SSDT.aml 放到 /EFI/EFI/CLOVER/ACPI/patched/下
变频成功，但不及 Windows 下完美，发热尚可接受。
