Doesn't sound like MySQL was installed properly. How did you install it (that document seems to have some choices)
I followed the directions exactly as they were provided in the moodle documentation.
"Download your version of Mysql from the Mysql site http://dev.mysql.com/downloads/mysql/ and install it! The dmg install will allow you to start or stop the MySql server from your system preferences. If you tick the option to start on boot then it may not actually start on boot. This is an on-off issue with OSX."
After the install in the documentation the step to grant privileges to the new user did not work. After I ran the commands I did a show grants; but the new users privileges were not created.
The following moodle document statement makes me think this article is outdated rendering it obsolete:
"If you are not running OSX Server then you will probably need to install Mysql again if Apple issues an upgrade of Yosemite."

Yosemite was released in 2014.
If you want resolve the problem change from localhost to 127.0.0.1
