Homebrew 的 Cask 已经支持 Docker for Mac，因此可以很方便的使用 Homebrew Cask 来进行安装：

在载入 Docker app 后，点击 Next，可能会询问你的 macOS 登陆密码，你输入即可。

停止 Docker 服务

在终端中输入以下命令，以停止 Docker 服务：

# 停止 Docker 服务
osascript -e 'quit app "Docker"'

这行命令使用了 osascript，它是 macOS 中执行 AppleScript 的工具。通过这个命令，Docker 应用程序会被安全地关闭。

启动 Docker 服务

我们需要重新启动 Docker。这同样可以通过终端执行一个命令：

# 启动 Docker 服务
open -a Docker

open -a Docker 命令会启动 Docker 应用程序。这个命令会找到并运行指定的应用。

确认 Docker 服务是否正常运行

# 检查 Docker 版本来确认运行状态
docker --version #或是 docker -v

正常显示docker版本说明已经正常运行。
