一、查看电脑mac

方式1： ipconfig /all 查看 本地连接 物理地址，注意：是 本地连接 的物理地址。

操作如下：

方式2：依次进入 控制面板–网络和 Internet–网络连接，注意：是 本地连接 的物理地址。

右键 本地连接 –属性–配置–高级–本地管理地址，输入要修改的mac地址，确定。

二、手动修改电脑mac

在上述 方法2 的基础上，手动修改成新mac地址（3CEBE），确认保存即可，查看检查确认。

验证是否生效：

三、Python修改电脑 本地连接 mac地址

运行效果：

本地连接 Intel(R) 82579LM Gigabit Network Connection
