For those getting error 66 trying to mount their root volume despite disabling SIP for authenticated root --> it means your system still has APFS System Snapshots enabled.  These can be removed following the steps below (credit to guide on reddit) 

 

Fixing APFS Snapshot Procedure

1. Boot into the Big Sur installer USB
2. Open a terminal, type `csrutil disable` and reboot
3. When back into the installer, run `diskutil list` to find the location of the "Macintosh HD" disk, such as disk2s5
4. Mount it using `diskutil mountDisk <disk identifier>` such as `diskutil mountDisk disk2s5` then run `mount -uw <volume mount point>` such as `mount -uw /Volumes/Macintosh\ HD/` to mount it as read write
5. Run `/System/Library/Filesystems/apfs.fs/Contents/Resources/apfs_systemsnapshot -v <volume mount point> -r ""`
6. Then, to delete the snapshots on the disk, run `diskutil apfs listSnapshots <volume mount point>` and take note of each UUID of the snapshots
7. Run `diskutil apfs deleteSnapshot <volume mount point> -uuid <uuid of snapshot>` for all snapshots on the disk.
8. Verify that there are no more snapshots by running `diskutil apfs listSnapshots <volume mount point>` it should return "No Snapshots for disk"
9. Reboot into the Big Sur desktop and make sure that running `sudo mount -uw /` returns no errors and that running `diskutil info /` returns a disk such as disk2s5 and not a snapshot such as disk2s5s1

Does the recovery mode already work in the Big Sur Beta2? I have the Recovery option in the OC but click on

only a black picture appears on it, then the OC boot menu comes back. I wanted to
Run csrutil authenticated-root disable for more access to Big Sur.

Thank you for Tipps

I run this above command one by one deleting snapshot but i stuck here

By using this command mount -uw

Please make a toturial for better understanding about deleting snapshot partition

@MorenoAv I am sorry that did not work for you.

 

You could remove these entries and try with current sysdef.

Share your EFI if possible.

Make usb big sur boot installer ( or catalina if big sur not) 

[crazybirdy]

a stupid question , have install before any version of catalina ?  i thinking no ... 

 

Just did some test.

Use createinstallmedia to make installer with 10.14.6, 10.15.5, and Big Sur beta 2,

then use OC 0.6.0 to install 10.14.6, 10.15.5 without issue,

and the installation is finished on stage1, stage2, and boot to system successful.

 

Big Sur beta 2 can finish stage 1 installation, and the APFS "macOS Install Data" is ready.

But boot to stage 2 ... it still gets reboot ... after -v boot log to apple logo.

 

I think, it may be the graphic card issue with my GT 640 cause of it always shows the log....

 

System is shutting down, (SIP is Disabled) allowing process at path: /System/Library/Extensions/IOGraphicsFamily.kext/iogdiagnose

Worked great for me. Got stuck at step 5 I think it was until I entered the “”
Now my DW1820A works and also fixed the lag I had with the menu bar.

As my Legacy BIOS, I can boot from Enoch, Clover, and OC.

 

boot1 = Enoch r2922 boot

boot2 = boot2 -> /EFI/OC/BOOTx64.efi -> /EFI/OC/OpenCore.efi

boot6 = boot6 -> /EFI/CLOVER/CLOVERX64.efi

 

and set boot=boot6 -> Clover default...

All three bootloaders work fine here via Clover-pkg to install alternative booting PBR.

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.

I followed [mention]fusion71au [/mention] guide to delete snapshot and it worked just fine, just pay attention to step 5’s (“”) the (“”) are needed. Check your config as I believe you need 77080000 not 7708000.

Boot picker I’m at a loss with, internal boot picker or open canopy?

I make a mistake in my comment: I've 77080000 in my config.plist.
BootPicker can be BuiltIn (just text) or external (graphical) like OpenCanopy

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

Hi @crazybirdy.  I'm nearly certain the problem lies with your graphics card.

 

My old legacy BIOS rigs can boot the Big Sur Installer and also the completed Big Sur installation on an external USB HD (via OC 0.6.0)...

 

Spoiler

 

but since they have non metal capable graphics cards, they also reboot on stage 2 (when attempting a new clean install from scratch).

 

If someone manages to fool the Big Sur installer that a metal capable graphics card exists (or that install is happening in a virtual machine environment), it would probably work.

What's your graphics card?

As shown in the screenshot (for system 2 in my signature), its an ATI HD5770, not supported since macOS 10.13.6 - no metal capability so running in vesa mode here.  Booting to Big Sur where installation was done previously onto an external USB HD (by my NUC6i5SYH with metal capable Intel Iris Graphics 540).

@manmo71, 

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