MySQL Workbench - Create new server instance error When attempting to create a new server instance I get an error at the 'Test Settings' step of the creation wizard.

The error:

What check_admin_commands/local
Operation failed: /usr/local/mysql/support-files/mysql.server start is invalid


I'm using MAMP and new to OSX so I'm not sure what the problem is here. I can't find the directory /usr on OSX, should I be changing Workbench's configuration to look elsewhere for mysql.server?

NOTE: Where the author suggests using the path '/Applications/MAMP/bin/stoptMysql.sh' at the end... there's a typo.

Should be '/Applications/MAMP/bin/stopMysql.sh'
