Lockdown, a Mac security configurator for El Capitan
Lockdown gives you a GUI front-end to the termain based tool osxlockdown which works by changing your Mac's setting to reduce surface attacks. It has two key functions.
1) Audit. Checking all settings and giving you an overall score based on what is and isn't enbabled. My final Score was 53%; Pass rate: 17/32
2) Fix. This allows to you turn on these "security" features. Though all ye who enter be warned, don't go clicking/enabling everything! Personally I need features like the iCloud drive and I don't want to "Secure Safari by crippling it".
