Gigabyte X299X - Catalina Support

yes, RTC, stupid me, I'm using one from TheBloke, but don't know why it doesn't work...

You can try my old EFI if you want.

I just deleted "agdpmod=pikera" which is for "Navi" gen 5000 graphics card.

It is made for Big sur (I think there is some modification to make it compatible with "mojave")

USB map made.

OpenCore 0.7.2

Hi
I will compare them
I'm running Catalina at the moment, but don't know if I will upgrade to Big Sur...
What BIOS are you running ?

Since Big on 11.3 the recent BIOS does not work

So if you are on mojave or big sur 11.2 you can use all BIOS ( even the last one )

But since 11.3 only the F3c and older BIOS works

How strange is that....

You also need to make a USB Map from big sur 11.3
You can use the one from my EFI if you want but I don't necessarily use the exact same USB ports (it depends on the case)
2 x USB2 ports and 2 x USB3.1+2 ports on the front case.
(Maybe there are 2 extra USB 3.1 ports activated, I don't remember)
And all rear USB ports enabled


you will have to copy the files:
- USBToolBox.kext
- UTBMap.kext


Otherwise use "USBToolBox" it's very easy

Anyone got Big Sur 11.6 working on X299X Designare 10G?
I've been pretty happy running Catalina on it, but it's time to move on.

Any caveats? TIA!

Hi @tosh71,

does the Gigabyte X299X Designare 10G work flawlessly at this point in Big Sur?
Thanks a lot.

big sur 11.6 works.
there are just some bugs in the F3c bios that will never be fixed since the new version of the bios does not work from big sur 11.3

for big sur 11.6 you need:
- F3c or older bios.
- make a USB map (since big sur 11.3) you can use "USBToolBox" it's very easy
- disable "XhciPortLimit" in Kernel / Quirks/

Any idea what the new BIOS are causing this issues ?
