提高Mac访问GitHub速度慢的问题

修改host文件

sudo vim /etc/host

添加以下内容

# Github
?
151.101.185.194 github.global.ssl.fastly.net
140.82.114.3 github.com 
151.101.112.133 assets-cdn.github.com 
151.101.184.133 assets-cdn.github.com 
185.199.108.153 documentcloud.github.com 
192.30.253.118 gist.github.com
185.199.108.153 help.github.com 
192.30.253.120 nodeload.github.com 
151.101.112.133 raw.github.com 
23.21.63.56 status.github.com 
192.30.253.1668 training.github.com 
192.30.253.112 www.github.com 
151.101.13.194 github.global.ssl.fastly.net 
151.101.12.133 avatars0.githubusercontent.com 
151.101.112.133 avatars1.githubusercontent.com

刷新DNS

dscacheutil -flushcache

如果出现无法访问github.com的问题,则是因为GitHub的IP地址可能更换,这时可以通过访问https://github.com.ipaddress.com 来查看新的IP,然后替换host文件中github.com的IP就可以了
