Greetings: In order to upgrade to the latest version, do I need to buy a new license or an upgrade. I am running macOS High Sierra version 10.13.6 Regards, AdolphR
Hello, in order to activate Parallels Desktop with a full license, you only need a license key for the version you are installing. And if you need to activate Parallels Desktop with an upgrade license, you need two keys: the upgrade key for the version you are installing, and a key for one of previous versions.
