How to use a script to Change Virtual Machine's configuration options

When you need to change the configuration settings of all virtual machines that are already registered on a Mac computer, you can use the Parallels desktop command-line interface. 

To do so, you first need to create a script to perform a desired configuration modification. 

To create a script, please follow the steps below:

1. Open the Script Editor application (Finder > Applications > Utilities > Script Editor).
   
   
    
2. Create a new script >  Click on "File" in the menu bar, then select "New Document" to create a new script.
    
3. Write the script > In the script editor, you'll need to write the code to change the VM options. 

The following is a script example that disables the auto-pause option for all virtual machines registered on a Mac computer:

for i in $( prlctl list -a --info | grep "ID" | sed 's/.....//;s/.$//' ); do prlctl set $i --pause-idle off done

Note: The script above uses the prlctl list command to first obtains a list of registered virtual machines and then (inside the loop) sets the --pause-idle option for every VM to "off". 

     4. Run the script > To run the script, click on the "Run" button in the Script Editor toolbar, or press Command + R on your keyboard.

The script will execute and make the changes to the VM options in Parallels Desktop.

(Please note that the script provided is a basic example, and you may need to modify it to suit your specific needs. You can refer to the Parallels Desktop documentation for more information on available commands and options)
