(1) 安装Shadowsocks和Chrome

brew install shadowsocks-libev
brew cask install google-chrome

(2) 安装Chrome插件Proxy SwitchySharp

https://chrome.google.com/webstore/detail/proxy-switchysharp/dpplabbmogkhghncfbfdeeokoefdjegm

(3) 配置

emacs /usr/local/etc/shadowsocks-libev.json

修改下面的配置
 {
      "server":"",
      "server_port":,
      "local_port":,
      "password":"",
      "timeout":600,
      "method":"aes-256-cfb"
 }

服务器请到https://www.shadowsocks.net/get发邮件获取，配置完成后是如下：
 {
      "server":"hongxchen.github.io",
      "server_port":1080,
      "local_port":8104,
      "password":"abc",
      "timeout":600,
      "method":"aes-256-cfb"
 }
 注意：method字段一定要小写

(4) 配置Proxy SwitchySharp

1. 添加新的的配置New Profile
2. Profile Name：Shadowsocks
3. 选择Manual Configuration
4. 在SOCKS Host中填入127.0.0.1和shadowsocks-libev.json中设置的local_port，如8104。HTTP Proxy，HTTPS Proxy，FTP Proxy空着不填。
5. 选择SOCKS v5

6. 切换到 Switch Rules
7. 勾选Enable Switch Rules
8. 勾选Online Rule List，在Rule List URL中填入http://autoproxy-gfwlist.googlecode.com/svn/trunk/gfwlist.txt，Proxy Profile选择Shadowsocks
9. 勾选AutoProxy Compatible List

(5) 测试

终端执行
/usr/local/opt/shadowsocks-libev/bin/ss-local -c /usr/local/etc/shadowsocks-libev.json

打开Chrome，Proxy SwitchySharp选择Auto Switch Mode
打开www.youtube.com等被墙网站，如果不能打开则https://www.shadowsocks.net/get发邮件获取其他服务的的配置

(6) 开机启动

Ctrl+C关闭在终端中打开执行的ss-local

制作/usr/local/opt/shadowsocks-libev/homebrew.mxcl.shadowsocks-libev.plist文件的软连接到~/Library/LaunchAgents
% ln -s /usr/local/opt/shadowsocks-libev/homebrew.mxcl.shadowsocks-libev.plist ~/Library/LaunchAgents/homebrew.mxcl.shadowsocks-libev.plist

(7) 加载配置文件

launchctl load ~/Library/LaunchAgents/homebrew.mxcl.shadowsocks-libev.plist

** 卸载为launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.shadowsocks-libev.plist

(8) 完成

到此配置完成，以后开机打开Chrome就能够翻出墙外，https://www.shadowsocks.net/get提供的服务器在一段时间后可能不能连接，只需关闭服务在shadowsocks-libev.json文件中写入新的配置项，重新启动服务就行了。

launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.shadowsocks-libev.plist
emacs /usr/local/etc/shadowsocks-libev.json
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.shadowsocks-libev.plist
