Checks your OSX machine against various hardened configuration settings.
You can specify your own preferred configuration baseline by supplying your own Hjson file instead of the provided one.
The authors of this tool are not responsible if running it breaks stuff; disabling features of your operating system and applications may disrupt normal functionality.
Once applied, the security configurations do not not guarantee security. You will still need to make good decisions in order to stay secure. The configurations will generally not help you if your computer has been previously compromised.
Configurations come from sites like:
You should download and run this application once for each OS X user account you have on your machine. Each user may be configured differently, and so each should be audited.
Download this app using Git, GitHub Desktop, or the "download as zip" option offered by GitHub. If you choose the zip option, unarchive the zip file after.
In the Terminal application, navigate to the directory that contains this app. You can use the cd command (see example below) to change directories. If you've downloaded the file to your "Downloads" directory, you might find the app here:
cd ~/Downloads/osx-config-checkNext run the app as follows:
python app.pyThis will take you through a series of interactive steps that checks your machine's configuration, and offers to fix mixconfigurations for you.
