mysql Unknown column 'password' in 'field list'

I am trying to change MySql root password.

What I have done is below.

1. Install MySql-5.7.6 ~ .dmg(Community Server) and workbench.
2. Turn off the server on OSX System preferences.
3. Access MySql with console. The command was mysqld_safe --skip-grant
4. Execute update user set password=password('1111') where user='root'; and got an error message --> ERROR 1054 (42S22): Unknown column 'password' in 'field list'.

FYI, I did use mysql;. So I did select query on user table and found password column actually does not exist.

It is very weird. Is it possible that original user table does not have password column?

How can I change password, which does not exist?

Thanks for your answer :D
