看到不少至强cpu和最近的haswell-e 和boardwell-e架构的在macOS系统关于本机中显示 “未知”，其实不是系统问题而是四叶草的原因，看了下四叶草cpu.c的源码case CPU_MODEL_HASWELL_E:
         return 0x507;
      case CPU_MODEL_IVY_BRIDGE_E5:
         return 0xA01;
      case CPU_MODEL_BROADWELL_E5:
         return 0xA02; //0xA02 or 0xA03

可以看出来 haswell-e的cpu返回的0x507，ivy-bridge返回的0xA01，boardwell返回的0xA02或者0xA03
接下来打开clover助手，本人的cpu是e5 2689 v4 属于boardwell-e，所以 cpu-type那填入0x0a02。

接着保存重启cpu就能正确识别了。

下面是本人实测过得
用0x0a01
Sandy Bridge EP
e5 2670

用0x0507不行的话试试0x0a01
haswell-e
i7 5960x i7 5930k i7 5820k

用0x0a02 或者 0x0a03
boardwell-e
i7 6950x e5 2789 v4

大家实测了的话，可以贴出自己的cpu以及使用的type。
