MAMP MySQL won’t start

If you use MAMP for local PHP/MySQL development on OS X then you’re likely to come across this problem with MySQL starting once in a while.

MAMP is a great bit of software but every now and then you will see that MySQL has a problem starting. Checking PHPMyAdmin you might see “Error: Could not connect to MySQL server!”.

Don’t despair, there is a very quick fix:

1. Quit MAMP
2. Open terminal and type: sudo killall -9 mysqld
3. Reopen MAMP

That will fix it but if it’s still not working you can try visiting this MAMP forum thread for more details.
