1、访问过慢解决办法
sudo vim /etc/hosts
添加
# Github

192.30.253.112 github.com
151.101.112.133 assets-cdn.github.com

151.101.12.133 avatars0.githubusercontent.com
151.101.112.133 avatars1.githubusercontent.com
刷新dns
dscacheutil -flushcache
#2、无法访问问题
通过查看 https://github.com.ipaddress.com ，查看github.com地址为140.82.114.
sudo vim /etc/hosts
添加
140.82.114.4 github.com
可以正常访问了！
