烦烦烦烦，由于之前在一台WindowsServer2012上面下载了Teamviewer没有看清楚是商业版的，然后安装运行了一段时间后到期了。虽然已经在WindowsServer2012上面卸载了Teamviewer但是悲催的事情就是，商业用途的情况一直未能接触，后来后知后觉才发现原来是安装过商业版之后，teamview的id就会被判断为商业用途的噩梦。

后来百般波折终于找到了原因，Windows的话需要用清理软件的工具清理干净Teamviewer并且重新修改网卡的mac地址后再重新安装才可以，Windows如何修改mac地址呢，其实非常非常的简单，看下面的截图就可以了。

Mac os的话就相对来说比较复杂了，一开始度娘了之后发现需要在终端修改，一般的命令是sudo ifconfig en3 ether 00:e0:4c:6c:05:f6就可以了的，但是死活不行，后来度娘了之后发现有更高级的方法，需要用到Python去修改应用目录的文件。

下面就不多说了，拷贝下面的代码在电脑中新建一个TeamViewer-id-changer.py的运行文件，然后在终端执行sudo python TeamViewer-id-changer.py即可，然后重启电脑你就会看到你的Teamviewer的id就会有所变化，注意macOS的话需要先安装然后终端执行Python文件，以下代码；
