macOS。如何以编程方式获取CPU温度

import IOKit
import CoreFoundation

func getCPUtemperature() -> Float? {
    let platformExpert = IOServiceGetMatchingService(kIOMasterPortDefault, IOServiceMatching("AppleSMC"))
    guard platformExpert != 0 else {
        return nil
    }
    
    var cpuTemperature: Float?
    let key = "TC0P" // CPU温度传感器键名
    let cfKey = key.data(using: .utf8)! as CFData
    let cfProperties = IORegistryEntryCreateCFProperty(platformExpert, cfKey, kCFAllocatorDefault, 0)
    
    if let properties = cfProperties?.takeUnretainedValue() as? NSDictionary,
       let temperatureData = properties[key] as? Data {
        let temperatureBytes = temperatureData.withUnsafeBytes { $0.load(as: UInt16.self) }
        cpuTemperature = Float(temperatureBytes >> 8 & 0b11111111)
    }
    
    IOObjectRelease(platformExpert)
    return cpuTemperature
}

if let temperature = getCPUtemperature() {
    print("CPU温度：\(temperature)℃")
} else {
    print("无法获取CPU温度")
}
