1. Download **macOS Catalina** from App store. This will be stored in the **Applications** folder.
2. From the Applications folder, execute `tar -zcvf installCatalina.tar.gz Install\ macOS\ Catalina.app/` in Terminal to **zip the application**.
3. The zipped application should be placed in a Windows share machine.
4. Download the [script](https://www.manageengine.com/products/desktop-central/catalinaosupgrade.sh). The script will connect to the share where the application is present. The application will get copied and the MacOS will be upgraded in all the target machines through Endpoint Central.

The format of the SERVERPATH parameter is given in the script itself.
