I need to deploy an SSL certificate for my Mac systems via DC. Unfortunately, it doesn't seem like there is any ability to simply run a script for Mac's. I've created a Zip of with the certificate and specified the command to import it into the System keychain (/usr/bin/security add-trusted-cert -d -r trustRoot -k /Library/Keychains/System.keychain root.crt) but the deployment always fails with 'Installable not found'
