Hi folks, I'm having trouble creating a new macOS VM from scratch from a macOS Installer. I'm running 13.2.0 (43213), Pro Edition. For example, I have the file "Install macOS High Sierra.app" for macOS High Sierra (10.13.2, 17C89). However the Installation Assistant does not detect it. If I try "Select a File" and navigate to its location, it is greyed out and unselectable. If I drag-and-drop the macOS installer to the Parallels Installation Assistant window, the assistant says "Unable to detect operating system". I was able to get this to work in the past, I thought with this version of Parallels and an installer for 10.13.2. The Assistant had then automatically created a second disk to hold the installer data and booted the VM off of that. Is there any way I can debug this? Alternatively, any way I can manually setup the VM with this installer? (Apologies if this thread exists already. I couldn't find anything about it in the KB nor in forum search)
I've worked around the issue by using the createInstallMedia command inside the installer bundle to create a fake "usb key" (by creating a disk image with Disk Utility, then pointing createInstallMedia at that volume). The Parallels Installation Assistant was able to recognize the fake usb installer. It's a hassle and waste of space, so I'm still hoping to find a solution for the root cause, but at least I'm not blocked.
