Macs没有像Windows一样的实例。一般来说，你希望应用程序运行两次，你实际上需要复制二进制文件，然后双击复制的版本。

Macs do not have instances in the same way as Windows does. Generally speaking you want the application running twice you physically need to copy the binary and then double click on the copied version as well.

如果你需要两个应用程序运行那么你不像Mac用户那样：）

If you need two instances of an application running then you are not thinking like a Mac user :).
