# For Kaspersky Endpoint Security for Mac installation, there are two seperate installation scripts that needs to be run on Terminal. Less tech-savvy users are struggling to follow this process.
# Following script installs Kaspersky Network Agent for Mac and Kaspersky Endpoint Security for Mac in one go without any user interaction (other than entering Admin password)

# How to use?
# 1) Create a standalone installation package for Kaspersky Network Agent for Mac from KSC Web GUI and put it in the same folder with this script.
# 2) Create a standalone installation package for Kaspersky Endpoint Security for Mac from KSC MMC and put it in the same folder with this script.
# 3) Change name of installation package, it is specified in "kes_installer" variable.
# 4) Preferably put all 3 files to a .zip file before sending to the client.
# 5) Pro-tip: If you change extension to .command, this script can be run by double-click (without asking client to run Terminal)
# Installation requires sudo privileges.
