Installation of macOS Catalina fails on X99 with Xeon CPU

[thanxse]

Hi,

yesterday I installed macOS on my new system. Actually, it`s high sierra. But now, I want to upgrade to macOS Catalina.

After create an bootstick with Catalina and try to boot, Clover stops at [PCI configuration begin].

The specs are:
2x Intel Xeon E5 2676v3 12 Cores / 24 Threads
X99 Motherboard Huananzhi
ASUS ROG Strix Vega 64
256GB SSD Intenso High Performance

EFI Folder is under the post.


Maybe someone knows how to fix this problem.
Thanks.


If my english is not so good, I apologize.

Please read and comply with the rules, in particular the one regarding profiles.
Link to profile - Just three items - Motherboard (or prebuilt system), Processor (CPU) and Graphics.

Your Clover version is too old to run Catalina.

I updated clover, but the boot process still stops at PCI Configuration Begin.

Try adding npci=0x3000 to your boot arguments.

MacOS still doesn't boot, with the flag. I think, it's the X99 Chipset Problem which have many users, right? Maybe switch to OpenCore? What do u think about that?
