MySQL Server Won’t Start on MAMP (RED LIGHT!) Mac OSX

If you can’t figure out why the MySQL Server won’t turn on if you’re using MAMP to do local development work, it could be because there are conflicting instances of a process called “mysqld” running on your system.

HERE IS THE SOLUTION

1. Open up the program called Activity Monitor on your Mac. Just search for it, or it’s under Utilities I think.
2. Search for a process called “mysqld“.
3. Click on that process and “Quit Process” that bastard.

Now open MAMP back up and start the MySQL Server. Should turn green. Hopefully that helped.
