How do you rename VMs?

Hello,
Thank you for reaching out.
As from Parallels 19, you can now have the setting to change macVM name.

1. Shut down the virtual machine.
2. Open virtual machine configuration.
3. In the General tab type the desired name in the Name field.

For more information, please go to the link https://kb.parallels.com/123125

If you do not have Parallels Desktop 19, to rename a virtual machine, please use the command below (In the terminal on the host):

prlctl set "macOS 13" --name "macOS 13 New Name"

thanks
