Raw
getMacUUID.swift
func getSystemUUID() -> String? {
let dev = IOServiceMatching("IOPlatformExpertDevice")
let platformExpert: io_service_t = IOServiceGetMatchingService(kIOMasterPortDefault, dev)
let serialNumberAsCFString = IORegistryEntryCreateCFProperty(platformExpert, kIOPlatformUUIDKey, kCFAllocatorDefault, 0)
IOObjectRelease(platformExpert)
let ser: CFTypeRef = serialNumberAsCFString.takeUnretainedValue()
if let result = ser as? String {
