After making the change to your config.plist NVRAM entry, don't forget to reset NVRAM from OpenCore boot menu.

Thanks @fusion71au It works now. Do you if there is a setting for also disabling Authenticated Root at the same time.
I don't understand why OC Picker show "BigSur - data" and not "BigSur HD" (I name BigSur my HD, of course)

Hi @Blu24 @crazybirdy @fusion71au

Finally, I succeed to install Big Sur Beta 2 on my USB external Hard Drive connected to Z390 Aorus Master More than 4hours for stage 2, and the others stages are long too.

TODO

disable SIP: strangely 7708000 in config.plist don't work for me

OC Picker show only BigSur - Data instead of BigSur HD

remove update snapshot

Any ideas ! Please.

Great News :thumbsup_anim:

Can you please upload a screenshot of "OC Picker show only BigSur - Data instead of BigSur HD"

Regarding your installation taking so long to install, I think if you were to installed Big Sur on a spare internal drive, the installation would be much quicker

I've 3 Hard Drives: Catalina and Windows (Internal), BigSur (External)

I can't rename USB - Data to BigSur - Data for the time being. This is why you see USB - Data on the screenshot. Sorry for my bad English.

I think it's to do with the new file structure. At the moment you can access your Catalina HD from Big Sur but you can't access Big Sur from Catalina. Have you noticed "Incompatible Disk info" Top right? when you boot into Catalina?

@manmo71,

I tried it, removed the said parameters and lost boot and graphic acceleration ...

Thanks

@MorenoAv I have just edited the Platform-ID for iGPU in your config.plist, everything else remains untouched.

Replace your existing config.plist (after backing up a copy) with this one and give it a try.

If this does not work, then I am out of idea's for the moment.

For disabling Authenticated Root, you can set the NVRAM csr-active-config parameter to 0x77080000 in OC config.plist, then resetting NVRAM through the OC boot menu or with booting to Big_Sur's Recovery/Installer USB and disabling it with csrutil in terminal (see my post on APFS Snapshot Procedure and the examples in it).

OC uses the content of the hidden text file /System/Volumes/Preboot/UUID/System/Library/CoreServices/.disk_label.contentDetails to label the macOS volume...

Spoiler

Also check your OC boot log eg if you have the debug version of OC, type in terminal

ioreg -lw0 -p IODeviceTree | grep boot-log | sort | sed 's/.*<\(.*\)>.*/\1/' | xxd -r -p

and you might see something like this output...

I can't explain myself well, sorry. When I boot on the Big Sur disk, OC only displays the data partition of Big Sur and not the System partition. So I have to boot on the data partition to start Big Sur. I hope that it's clearer.

I will continue the investigations proposed by Fusion71au

Re-download BS Beta 2, recreate USB with your EFI folder, launch install to USB hard drive .... Stuck "Less than a minute remaining" since 15 minutes

Same problem trying to install on a USB3 flash drive. I was able to install successfully on an external USB2 hard drive. There was mention of the installer being unable to “bless” a USB3 drive in another forum (MacRumors).

Finally my Big Sur beta 2 is running 99% with Opencore and I would like to thank everyone for helping each other in achieving such great hacks. I am waiting for the next challenge ;-).

The other strange thing is that when I want to modify system files I have to boot with Clover, as I still get error 66 when booting with Opencore and to be honest I don't mind, as I am learning quite a lot in the process. My Airplay is now also up & running after moving to AR5B95 wifi card. Trackpad with gestures was fixed by installing the VoodooPS2Controller-Mojave.kext in Library/Extensions, as Opencore did not want it at all and I will try later again. Now trying my luck with installing the second Intel WiFi in the 1/2 mini for the bluetooth and will let you know if I succeed ;-)

Well people of the palace I have succeeded with the installation of the second wifi card in the 1/2 mini slot of my dell, in order to have a working bluetooth from the Intel card, while I am getting wifi from the Atheros card and all is working :thumbsup_anim: :drool:

Thanks a lot I follow all your explantations:

OC Debug: I don't have any output with Ioreg command. macOS 10.16 recognizes the right names which is not the case with Opencore. Strange.

SOLVED change name in the hidden text file /System/Volumes/Preboot/UUID/System/Library/CoreServices/.disk_label.contentDetails

Blu24, yes that's what i observed too when i boot into Catalina. When in Catalina the incompatible disk message will appear and on the desktop i can see the update disk.

So you or anyone have any idea what is it and how to resolve it? Thanks.

me too have dw1820a, lately i have tried the tutorial from @fusion71au and successfully delete the APFS snapshots, but when i replace bigsur's IO8211Family kext with the older one from catalina 10.15.5, i got some wrong messages when rebuild kext cache. I still insist to reboot my laptop, then it's get stuck.
if you dont mind, could you share your IO8211Family.kext that working well with DW1820a?

The only way I can access to BS from Catalina is from Disk Utility. Right click/Show in Finder.

I used the one from iPixelGalaxy’s video.

I’m not sure which version of macOS it’s from to be honest.

Make sure you run all commands after you have replaced the kext.
