Description

As described on wazuh/wazuh-packages#2205, since macOS Ventura 13.4 and its Secure Integrity Protection mechanism is not allowing to run launchctl setenv and launchctl getenv as root user .

To solve this problem, a custom temporary file will be created with the desired Deployment information and will be consumed by the installer, being removed after being read.
