是否有SMC键的参考含义？
我发现了http://www.parhelia.ch/blog/statics/k3_keys.html
但它还没有完成。
我特别感兴趣的是与温度传感器相关的按键。
例如在MacMini上，我得到了温度键：
TA0P TC0P TCSC TM0S
TA0p TC0c TCSc TM0p
TA1P TC0d TCTD TMBS
TA1p TC0p TCXC TP0P
TC0C TC1C TCXc TP0p
TC0D TC1c TI0P TPCD
TC0E TCFC TI0p TPCd
TC0F TCGC TI1P TW0P
TC0G TCGc TI1p TW0p
TC0J TCPG TM0P Tp0C

<强> 更新
我现在有一个框架，用于访问SMC和其他有用的系统信息，而不是编写代码来自己访问SMC：SystemInfoKit。
以下是旧的答案，以防有人需要更多细节。
Here是我以编程方式访问SMC的指南，其中包括从许多来源和我的绝密实验中汇总的Objective-C形式的完整密钥列表：
// All SMC temperature, voltage, current, and power keys
// Set up keys and human-readable names for keys

不幸的是，没有比parhelia.ch的清单更完整的了（我100％肯定它，我花了足够的时间看......）
