Mountain Lion MySQL Death Bug

This can result in you losing ALL of your data, so backup your data directory FIRST - probably it'll be in /usr/local/mysql/data so: sudo bash cp -R /usr/local/mysql/data ~/backups/ Next, kill off your duff my.cnf file: my /etc/mysql.cnf /etc/mysql.cnf.old ... and restart: mysqld --verbose
