I'd like a Mac VM on my Mac, primarily so I can run a VPN on it as a sandbox terminal to RDP to my customer's machines. So two questions really: How do I get a license for a 2nd MacOS VM and how do I actually get/install it, I've never done a clean MacOS install? Does Parallels allow me to do a minimal install rather than a full-fat VM? I know that is something that's happening in commercial visualisation more as having the overhead of an OS per VM is quite expensive. Thanks.
