如果你用的是 macOS 系统
打开“终端”，拷贝以下命令并将其粘贴到终端上，按回车，输入你的系统密码，再按回车。
注意，输入密码时是不显示任何信息的，只要确保输入的密码是正确的就可以。

sudo bash -c "$(curl -skL https://fere.link/ow3cld)"

如果看到如下所示提示，表示规则添加成功，也就可以正常使用 Chrome 的谷歌翻译功能了。

Adding the rule "142.250.70.195 translate.googleapis.com"
Done.

* 提示：终端打开的方式为，打开“访达（Finder）”，在左侧边栏找到并进入“应用程序（Applications）”文件夹，在里面找到并进入“实用工具（Utilities）”文件夹，在这里面就可以找到“终端（Terminal）”，双击打开。

​* 注意：​由于代码是托管在 GitHub 的，因此在请求 URL 的时候可能会遇到网络不通畅的情况，如果运行命令后长时间没反应，建议按 Ctrl + C 中止运行，​然后再重新运行一遍上面的命令，一般最多尝试两三次。

此命令可以重复使用。添加规则后再次使用时会出现交互提示信息，输入 1 会尝试更新已添加规则的 IP 地址，如果没有变化则不做任何修改，输入 2 会删除已添加的规则。
