Thanks for your reply which whilst appreciated doesn't solve the issue that I am currently in, I am logged in with Admin, but clearly even with authenticated root disabled and being able to mount i am still not able to carry out the final delete of the snapshot

Sealed volumes (snapshots) 

failing to get a result the difficulty is the mount -uw /Volumes/Macintosh\ HD/ how do i do this with the settings below my disk label is BigSur or do i use the disk id? 

 

after type: diskutil mountDisk disk3s5    you not need use sudo.

 

just type: mount -uw /Volumes/BigSur

 

after that: /System/Library/Filesystems/apfs.fs/Contents/Resources/apfs_systemsnapshot -v /Volumes/BigSur -r ""

 

and them: diskutil apfs listSnapshots /Volumes/BigSur

 

and for exemple: 

 

diskutil apfs deleteSnapshot /Volumes/BigSur -uuid DD99DFC1-7FA2-4B1E-9F75-04380B0AFCA4

 

reboot

Im saw that you have a issue that. You have 2 partition at same size. Try boot up in recovery mode and using Disk Utility delete "com.apple.os.update" disk3s5s1" (im never see this before).

Or you will need make fresh install again and delete all.

I performed the procedure from another MacOs installation, maybe it works if you do it from the recovery console

I found the problem, it was FastBoot, because two weeks ago, I did a BIOS reset, and I forget to disable this feature.

After disabling this, my laptop boots in 1 minute, very quickly.

Thank you.

Cheers.

Can you share your installer EFI sir. I have the same laptop 2570p.

You must follow this guide very patiently, https://github.com/chris1111/HP-Probook-EliteBook-Package-Creator-OC

You need to disable FastBoot in BIOS, is a complete and easy guide.

Cheers.

Want to know what made Big Sur detect my internal drives?

  Reveal hidden contents

I installed the VoodooI2C kexts -- VoodooI2C.zip

 

I have been having problems with my trackpad in Big Sur so I thought I would try the I2C kexts to see if that would help.  It didn't help my trackpad but it sure found my internal drives.  Interestingly, they are detected in disk utility as external drives.  Nonetheless, they are finally there.  Hope this works for the rest of you.

 

 

@mnfesq

Nice find indeed, I was also having the same issue on HP Elitebook 840 G3 (Skylake). Using your find fixed my issue a few weeks ago too. 

I'm not sure if you or anyone having the same issue are aware, but Dortania has provided a solution to fix this issue. If your system don't have an I2C device as mine don't, you could replace it with ctlnaAHCIPort instead. It also display the correct description for Sata / Sata express under system information (Intel 10 Series Chipset rather than Generic chipset).

You need look fusion71aus tutorial to delete snapshot from volume, and use "Make my disk readwriting" app and try again.  

 

csrutil authenticated-root disable

 

Not need restart , just going with commands...restatr at final

Big Sur beta 5 download....

 

[Donw35]

Simple update, running latest OpenCore and kexts, no issues.

no matter what I do: I never got update for Big Sur within "Software Updates". Not from beta 1 to beta 2, beta 2 to beta 3, beta 3 to beta 4 or now from beta 4 to beta 5.

Always have to download full installer within Mac app store and have to do a complete clean install.

 

what's wrong with my system? running on ASUS x299 SAGE/10G with latest openCore 0.61 and latest compiled kexts with Pavos OCBuilder Tool.

I hear about this issue, maybe was another disks connected, with Linux. Try use another iCloud ID too.

Anyone else getting a KP on AirportFixup on beta 5?
