在Windows上,我们生成一个与PC绑定的唯一密钥,用于将许可证与PC关联。这是一个使用C++和wxWidgets编写的应用程序,理论上跨平台兼容,但未在Mac端进行维护。我们使用一些Win32特定的代码来生成密钥......我该如何在Mac上实现类似的功能呢?

通过仔细阅读whitelionV和blahdiblah的答案,我找到了这个有用的页面:

虽然MAC地址看上去更加可靠和预测,但是他们警告说:
使用网络启动的时候,多个内置以太网口的系统会出现问题。这些系统的主要以太网口是连接到NetBoot服务器的。这意味着搜索主要端口可能会返回两个内置MAC地址之一,具体取决于哪个端口用于网络启动。值得注意的是,“内置”不包括驻留在扩展卡上的以太网口。
我担心这意味着您不能始终获得相同的值?
system_profiler
命令并查找“Serial Number”来获取序列号。/usr/sbin/system_profiler | grep "Serial Number (system)"
可能有一种编程方法可以获取相同的信息,但是我不知道它。
为了唯一地识别任何机器,您可以尝试使用MAC地址。虽然这个过程并不是微不足道的,但它相当简单。有很多跨平台开源库。
实际上,您可以尝试这个苹果开发者example
