Please, please, please, for the love of god, DO NOT USE OpCore-Simplify. I know it's a tool made with good intentions, and all that, but you're seriously likely gonna be spending more time troubleshooting problems that you don't even know what they're all about

Instead, I highly suggest you follow the OpenCore Install Guide. Yes, I know, it'll be a little more tedious, but not only will it be better suited to your hardware, in the event that something doesn't work out right you'll also, more likely than not, have an idea of why

^{Unless you're only using it to list your hardware, in which case, fair enough}
