###1、查看电池信息

ioreg -rn AppleSmartBattery | grep -i capacity

# 返回信息
"AppleRawCurrentCapacity" = 4815
"AppleRawMaxCapacity" = 7222
"MaxCapacity" = 7222  # 目前电池最大容量
"CurrentCapacity" = 4815
"LegacyBatteryInfo" = {"Amperage"=0,"Flags"=5,"Capacity"=7222,"Current"=4815,"Voltage"=11885,"Cycle Count"=323}
"BatteryData" = {...}
"DesignCapacity" = 8790  # 电池出厂容量

###2、查看硬盘信息

smartctl -a /dev/disk0

# 返回关键信息
