MP 1,1-5,1 Losing My Mind Over Open core Boot Issue

[zyhter05]

(Apologies if this is the wrong forum or thread, I'm new to this site)

The past week, I've been attempting to get OS Monterey 12.7.3 on my Mac Pro 5, 1. It has been nothing short of a headache and it's at a point where I don't know what to do. The initial update worked fine enough, however it rendered my bluetooth and wifi card useless. Upon buying a new one card, I installed it and went through the process of replacing kext files using OpenCore Generator.

This past attempt I must've put the kext files in the wrong order because now all that happens is my Mac will show the "Mac HD" on the boot screen and then go to the apple logo and stay there. (It cycles through this process on its own) No loading bar or anything. When I try and boot to recovery mode I get a string of messages ending in "Halting on Critical Error."

I even tried reinstalling the Monterey file onto a USB. It allows me to select the USB as the boot, but still gets stuck on the apple logo.

I’ve tried booting verbose and see the issue is Airport BRCM fixup kext is missing. It seems like I removed this trying to fix the Bluetooth and wifi thing, had no idea it would cause these issues! Just following YouTube videos

This is more than frustrating, I'm not a computer genius by any means but I've been following what most resources have been saying. How do I get past all of this and re-organize the kext so my computer can boot properly? I can't even get to recovery mode to use terminal for anything.

Please...any help would be much appreciated. I'm a full time music producer and this computer is where I work.

Try OCLP, which configures things for you. It uses only OpenCore on Monterey. It does rootpatching in addition for Ventura and Sonoma, but due to incomplete AVX2 support that does not work that well for me.

did you use MLO opencore specifically for 5,1 or just opencore

Do you have a disk that you can put in that will boot to a supported version of MacOS (i.e. Mojave)? Note that this might require you to also go back to your original GPU card to be able to select the disk with the supported OS for booting. I think that you're going to need to be booted into some working environment to be able to work on this problem, and you likely are going to have to start over with installing OpenCore and Monterey. This might also mean that you'll need a scratch disk as a destination target.
