首先打开Mac 自带的 terminal:

Go to mysql/bin directory(到该目录下)

$ cd /usr/bin
Start a mysql deamon with this option:

$ sudo mysqld_safe --skip-grant-tables
Open another terminal and open a mysql session to execute this: （再开启一个terminal : 快捷键 command + t）

$ mysql

mysql> use mysql;

see Note1 below for next line.
mysql> UPDATE user SET authentication_string=PASSWORD(‘YOUR_NEW_PASSWORD_HERE’) WHERE user = ‘root’; //蓝色的就是你要输入的新密码

mysql> exit;
Now kill the mysqld_safe process and restart mysqld normally:

$ sudo service mysqld start

就是这么简单！

Note1: password is the column name in table mysql.user prior to version 5.7. After which it became authentication_string. Change your update statement accordingly.
