Okay, so I've come back with much more progress. I used this guide provided by an admin to install High Sierra (https://osxlatitude.com/forums/topic/8506-dell-latitude-inspiron-precision-vostro-xps-clover-guide/#comment-94956). Basically, whenever it mentions a MacOS version, I replaced it with High Sierra. All was working well, and it seemed like it was finally working out. Got into clover on the USB, picked the "boot to MacOS" option, and after a bit of waiting it brought me to a screen showing "macOS could not be installed on your computer" and now I'm unsure how to proceed.
I followed the guide to the T, I even triple checked to make sure that i used the correct bootpacks with the EFI file and everything, which I did. So what am I missing? I used the 5450_HS_A19 bootpack, which matches my machine. However, this PC ships with a 720p screen, and I recently replaced the stock panel with a 1080p IPS panel, would that have something to do with it?
If more detail is needed please let me know, but if someone could point me in the right direction that'd be great
