The old method is not working on macOS BigSur. However, we can fix the Unknown CPU name or change it to any CPU type you want. I will describe this simple method using terminal code.

[Guide] Big Sur in X299 Designare EX with Opencore Boot Loader
Hello Folks! I just finished building my own customac in macOS Bic Sur system. In this time, I used a new boot loader called ‘Opencore’.
As you guys know, I used to use Clover boot loader instead, but this new macOS Big Sur (Version 11.0.1) is more reliable on the Opencore system. It is possible to use Clover as well, but there are some unreasonable errors and inconvenient issues during the clean installation. For more stable system to be owned, I’ve tried the Opencore boot loader and I successfully installed macOS Big Sur in my X299 Designare EX system. It is so far so good!

Hi folks!
I’ve successfully upgraded my macOS Catalina (10.15.7) to macOS Big Sur (11.0.1) with my original Clover boot loader through a normal apple’s update method. If you still using my EFI from Catalina, you could do update your macOS as well with some modification. I will show how to do that in this post.

This guide shows successfully running my iMac Pro intel 8th, 9th CPU’s Customac Build with macOS Catalina. You can also System Update up to the newest one smoothly after finishing the installation.
This post constitutes a new macOS 10.15 Catalina Desktop Guide for intel’s 8th and 9th CPU, which certainly can still grow and improve by your estimated user feedback. This macOS 10.15 Catalina Desktop Guide based on the Gigabyte X299 Designare EX. However, also other X299 series mainboard models or 300series mainboards of other brands might be compatible with this guide after likely considering and implementing few mandatory modifications not accounted by this guide. If you want to see previous Guide for macOS Mojave I linked it below for your convenience. The Mojave guide including some other MB’s EFIs conveys a common guide not only 300series but also X299series. But this Catalina guide is only for X299 Designare EX but limited for the X299 Series as well.
