解决 Parallel Desktop 16 在 macOS Big Sur 无法联网问题

问题简要

在 macOS 更新到 Big Sur 之后，Mac 平台非常好用的虚拟机软件 Parallel Desktop 在运行 Windows 时，可能出现客户机无法联网的情况，让人很恼火。网上给出的命令行方法非常不好用，每次都要通过命令行才能启动，且启动后还丢失了一部分文件内容。在国内外大神经过一段时间摸索后，给出了替换文件大法解决，感谢群成员 @无事摸鱼,有事烧纸 提供。

解决方法

简单来说就是把下面的代码储存为 network.desktop.xml，替换以下路径的同名文件：

/Library/Preferences/Parallels

上面的路径可以在访达按下 Shift + Command + G 快速跳转。

文件内容如下：
