- (NSString*)macAddress
{
    NSString* result = nil;

    char* macAddressString = (char*)malloc(18);
    if (macAddressString != NULL)
    {
        strcpy(macAddressString, "");

        struct ifaddrs* addrs = NULL;
        struct ifaddrs* cursor;

        if (getifaddrs(&addrs) == 0)
        {
            cursor = addrs;

            while (cursor != NULL)
            {
                if ((cursor->ifa_addr->sa_family == AF_LINK) && (((const struct sockaddr_dl*)cursor->ifa_addr)->sdl_type == IFT_ETHER) && strcmp("en0", cursor->ifa_name) == 0)
                {
                    const struct sockaddr_dl* dlAddr = (const struct sockaddr_dl*) cursor->ifa_addr;
                    const unsigned char* base = (const unsigned char*)&dlAddr->sdl_data[dlAddr->sdl_nlen];

                    for (NSInteger index = 0; index < dlAddr->sdl_alen; index++)
                    {
                        char partialAddr[3];

                        sprintf(partialAddr, "%02X", base[index]);
                        strcat(macAddressString, partialAddr);
                    }
                }

                cursor = cursor->ifa_next;
            }

        }

        result = [[[NSString alloc] initWithUTF8String:macAddressString] autorelease];

        free(macAddressString);
    }

    return result;
