  • Boot into Catalina

  • In Disk Utility, right-click. rename your USB

 

 

Thanks :) I don't know why, Picker see only data partition instead of main partition :cry:

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.

Hi Chris, could you upload your EFI folder for this HP Probook laptop?

Thanks.

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)

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...

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... 

17:915 05:721 OCB: Should boot from 8. Big_Sur (T:2|F:0|G:0|E:1|DEF:0)
17:916 00:000 OCB: Perform boot Big_Sur to dp PciRoot(0x0)/Pci(0x14,0x0)/USB(0xD,0x0)/HD(2,GPT,C3AD6E1F-42A9-4F06-98A4-5CC879F6554E,0x64028,0x6F80FC8)/VenMedia(BE74FCF7-0B7C-49F3-9147-01F4042E6842,35D21426674BBC44A2CC3FC394EAD3BC)/\1DF588CB-10D4-48C2-BE99-71CF80DD2FBF\System\Library\CoreServices\boot.efi (0/0)

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

Good news :yes:
 

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 :whistle:

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.

glad to hear that your DW1820a is working now on big sur
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?

When I made a clean install of Big Sur via USB, this doesn't happen.

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.

https://mega.nz/file/AOoTXSCJ#P6lgSvNaj_LZp-lCG2kudZccuZ9-pn355hzOp0G-UhM

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.

I didn't know you could access Big Sur using the open finder, Technically the file structure is different because you can not access the normal way, like previous versions of macOS. 

Regarding I'm wrong In 90% of cases. That's your opinion!!!

I'm only going by my experience. I can install Big Sur Via USB, using my original EFI settings, I compiled from source(OC 0.6.0) :)

1. The UUIDs are something like this "1486A08F-9233-452B-85F3-50D6B1ECE523B"

2. When I run this command "diskutil apfs listSnapshots <volume mount point>" this will give you a list of UUID, take a good look at the output, in my case I had two

3. This command "diskutil apfs deleteSnapshot <volume mount point> -uuid <uuid of snapshot>" will delete the UUID you must do with each. Example "diskutil apfs deleteSnapshot <volume mount point> -uuid 1486A08F-9233-452B-85F3-50D6B1ECE523B"

4. Finally to verify that all the UUIDs have been removed run again "diskutil apfs listSnapshots <volume mount point>" and the output of this should be "No Snapshots for disk"
