在mac经常需要安装一些软件，你可以通过app store下载，或者可以通过浏览袭搜索下载。这里介绍通过homebrew安装一些软件，它会自动为你下载一些软件的相关依赖，免去安装的烦恼。
首先我们需要安装brew，复制如下内容，在terminal中执行，等待安装完成
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
安装成功提示，部分截取

之后我们就可以用brew install xx 来安装软件了。 比如：
brew install git
brew install wget
brew install zsh
