解决Mac下idea运行速度慢

刚入手Mac，发现Mac下使用idea进行调试极其慢，然后发现和本地回环地址有关：

只需稍微修改hosts文件即可：

sudo vim /etc/hosts，在localhost后面追加你的电脑名.local即可

##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting.  Do not change this entry.
##
127.0.0.1       localhost       miaoying-MacBookPro.local
255.255.255.255 broadcasthost
::1             localhost
