I installed MySQL 5.7 from a .dmg package installer for Mac OS X. I followed the installer taking note of the temporary root password given. After the installation, I cannot login as root because the password expired. Here’s what I did.
I stopped MySQL in System Preferences.
Switched user to root.
$ sudo su
Started MySQL in safe mode.
$ sudo mysqld_safe --skip-grant-tables
I opened another terminal tab/window and lauched mysql shell there.

Now try logging in with the new password.
$ mysql -u root -p Enter password:
