[solved] Clean install Big Sur Z370 AORUS ULTRA GAMING WIFI OpenCore

[noviceiii]

Hellö

I have a working OpenCore 0.6.5 EFI after hours of work. I thought to share it.
Its ment for Z370 AORUS ULTRA GAMING WIFI, i7. I have removed the stock NVM bluetooth module and put a bluetooth card in it that is supported by apple natively.

Preparation:
- Download EFI Mount: https://github.com/corpnewt/MountEFI
- Download GenSMBIOS https://github.com/corpnewt/GenSMBIOS
- Download Big Sur from AppStore
- Download attached EFI, unzip it


Steps to install (to do on a Mac):

1. Format (erase) an USB stick
   - Journaled, GUI Partition Format
2. Create the installer on the USB stick.
   - The first path ist the the path to your Big Sur file, "MyVolume" is the name of your boot stick
   sudo /Applications/Install\ macOS\ Big\ Sur.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume
3. Mount EFI of the USB stick (open MountEFI.command)
4. Copy the downloaded folder to the mounted EFI (mind that it needs "EFI" as the first folder although the mounted drive is called EFI)
5. Open GenSMBIOS (double click GenSMBIOS.command), select one after the other
   1. install / Update MacSerial
   2. Select config and add the config file from your EFI/EFI mount
   3. Generate and use iMacPro1,1
   - Ensure, that the serial number is unknown here: https://checkcoverage.apple.com
   ... otherwise iCloud and iMessage won't work.
   4. Gnereate UUID
6. Put the stick into the machine you want to install big sure
7. Install OS X Big Sur (delete existing partitions completely)
8. Login to Big Sur, Copy the content of the EFI Folder from the USB stick to the EFI Folder of your new OS X (the folder might be empty, that's ok)

Hope someone can use it.

Ok again me. OpenCore is not for me for now. So I downloaded the shell.efi to a usb and then I followed this https://www.tonymacx86.com/threads/...boot-entries-prevent-further-problems.175274/

did you try to run this EFI on a MacBook Pro?
This config may not work on any other hardware than specified (Aoros Maiboard Z370)..
and yes, I had a while getting familiar with OpenCore as well. Clover was easier to start with. However, I start to like OpenCore sort of.

Hi @noviceiii, thanks for kindly sharing your EFI with the community! I have this same motherboard.

Were you able to do a USB Map and update to Big Sur 11.6?

Important Update: June 2023 From Big Sur 11.3 on the built-in OpenCore XhciPortLimit quirk no-longer worked as described. This became a known "bug", though in reality it was Apple changing their internal code, making a simple "peek and poke" to keep it operating, a difficult task. However, with...
