I have used the binary installer on my mac and use the following to start mysql.
sudo /Library/StartupItems/MySQLCOM/MySQLCOM start
It seems to start ok, but i haven't set up any passwords for users yet. I followed the instructions here from MySQL https://dev.mysql.com/doc/refman/5.0/en/default-privileges.html
mysql> SELECT User, Host, Password FROM mysql.user;
This just returns
-bash: mysql: command not found
I'm a first time mac user and don't really know how to fix this?
