X299 Big Sur Support

[oli.mathieu]

this is a known problem with the speech in the installer. Change to US (EN) in config.plist NVRAM > Add > 7C436110-AB2A-4BBB-A880-FE41995C9F82 >prev-lang:kbd -- (as "string") "en-US:0" or "en-EN:0" and everything should work... - dont`t forget NVRAM-Reset or in config.plist -> NVRAM > Delete > 7C436110-AB2A-4BBB-A880-FE41995C9F82 > insert the kind "prev-lang:kbd"

I'll test (Next week-end) That and will give an update
Thanks
EDIT
Now I remember a 1s picture before the Grey screen: Language selector was written in the the menu bar

if you use the new Beta 11.0.1, it seems this isn't necessary. There are are again more languages in the installer... but you can stay on EN in config.plist -> in your installationen you can choose your prefered language, and so you are safe for further updates which propably comes again only in EN...

It was the language
pfff I 'm ashamed
Now the the installer reboot before finish, "12 min remaining".
I suspect an NVRAM issue, but it seems to work.
Keep searching

If you would have also Catalina HD plugged, could you boot on it from macOS Big Sur Startup Disk Prefpane ?

Good day everyone, I'm rocking a Gigabyte Designare EX x299 board with and Intel i9-9900x and everything runs smooth on Cataline using Clover.

I'm tempted to give this a test, but I've never used OpenCore before and a lot of the stuff I'm reading is all new to me, has anyone here been successful with that board ? If so would you mind sharing your proceedings ?

Thanks a ton for the effort everyone.

As a starting point:
- read the first page on this thread
- there are many links for useful tips and for EFI OC for X299 Gigabyte.
- Dartonia Openencore install guide
- be patient but no reason why you couldn't get started with Open Core
