So, I'm stuck in a Catalina boot loop. There are a couple older mentions of similar symptoms, but one of them never got answered, and the other seemed to be during install. The install finished and I got to the OS, set up remote login. I shut it down to edit config, and it won't boot back up. I get it even if I restore everything back to the default settings before I made any changes. I get the Apple logo, the progress bar gets a few ticks along, then it loops back to a terminal window (I've attached a screenshot of that) then it goes to the Clover screen, then it tries to boot again until I force a stop.
I can mess with settings and force the graphical issues if I want, and in that case, it seems to actually boot, but I need to get in to some system settings.
I am going to try a High Sierra install, I need to access this remotely for emulating iOS for Xamarin, so I don't care if it's headless, but I need to get at some settings. I can't spin down my array at the moment, as it's rebuilding and has 20 hours to go, so all I can do is poke at the XML and I'm just learning what these things all do.
Here is my XML as it currently stands (mostly OOB standard, but I did add a couple cores just to see if the problem was not enough resources when it just got a couple old-ass cores). But I think 8GB and 4 cores (even if these are 10 year old Xeons) should be enough to at least boot.
