有时需要获取一个mac的序列号，然后您就可以验证。

Sometimes it is required to get serial number of a mac, and you validate on that.

我需要相同的，几年前，当我开发了一个插件。我被要求释放它在这样的方式，只有很少的系统可以使用该插件。

I needed the same, few years back, when I developed a plugin for OsiriX. I was asked to release it in such a way, only few systems can use that plugin.

如果我们得到比这更好的解决方案，这将是对我们所有人非常有帮助。

推荐答案

以下代码主要从，
稍作修改以返回 NSString 并使用ARC编译：

The following code is mainly copied from Technical Note TN1103,with small modifications to return an NSString and to make it compile with ARC:

#include <IOKit/IOKitLib.h>

- (NSString *)getSerialNumber
{
    NSString *serial = nil;
    io_service_t platformExpert = IOServiceGetMatchingService(kIOMasterPortDefault,
                                     IOServiceMatching("IOPlatformExpertDevice"));
    if (platformExpert) {
        CFTypeRef serialNumberAsCFString =
        IORegistryEntryCreateCFProperty(platformExpert,
                                        CFSTR(kIOPlatformSerialNumberKey),
                                        kCFAllocatorDefault, 0);
        if (serialNumberAsCFString) {
            serial = CFBridgingRelease(serialNumberAsCFString);
        }

        IOObjectRelease(platformExpert);
    }
    return serial;
}

您必须将IOKit.framework添加到构建设置中。

You have to add the IOKit.framework to your build settings.
