I'm utterly baffled at the moment. I've been trying to setup a VM to run some older software and cannot get El Cap, Sierra or High Sierra to install. Parallels 15 identifies the installers and loads to the installation screen. I can run the utilities, but if I choose "Install OS X" and click continue nothing happens. Not even after several minutes.
Is there a required setting I'm missing? This is on a new Mac Mini and I am installing onto an external drive rather than the system SSD.
Thanks
