[pre-release] macOS Big Sur

[Stefanalmare]

For developers, if you need it: after yesterday compile of OC I have no need of JumpstartHotPlug enable for recovery. Test it on ivybridge and z390. After today compile, for the first time on BS, I have KP on cpupowermanagement on ivybridge laptop. No problems on z390. TY for your work!

In BS beta 5 I have problems with airdrop on laptop and desktop ivybridge. Anybody else?

Thanks @Pavo. Still is an icon-less IORegExp, but it is 5 years newer than the IORegExp v2.1 from 2008 I've been using. I guess I'll call it progress  

 

 

so now I have 6Mb of more information ???

[Alex HQuest]

@iCanaro You have more details that were not shown before with the 2.1 version.

delete /Volumes/BigSur 

 

try this>>   diskutil apfs deleteSnapshot disk2s5 -uuid 7A9F57F5-FC3C-4199-A82A-BD3345EF8BDF

@Andrey1970 JumpstartHotPlug is fixed, so enable it is not necessary.

 

What about ScanPolicy! Before the fix, I put JumpstartHotPlug=enable and ScanPolicy=0 to boot recovery. Can I use my custom ScanPolicy now! 

Thanks.

Does anybody know how to get rid of those cosmetic apfs_keybag_init errors? 

I just turned off verbose mode and apple debug

Hi Andrey! Any chance to use EnableJumpstart on HP laptops, instead apfs drivers?

[Donw35]

On my HP 840 G3 Elitebook I have EnableJumpeStart=True and UnblokFsCionnect=Tree, no apfs driver needed

Hp 4540s. I don't see apfs partition using standard config. I need EnableJumpeStart disable, UnblockFsConnect enable and apfs drivers.

Anyone with Hp Probook has managed to dual boot Big Sur and windows 10 with OpenCore on one single disk, on my 4540s windows start but crash immediately, with clover worked smoothly.

Me. Tell me if I can help you. Windows boot from refind and also from OpenCore.

On single disk or two disks with caddy, on my laptop refind work well but OpenCore has some issues to handle the dualboot, can you share your efi folder and show your partition map. Thank's in advance.

This is third time you ask me this! On SAME disk. Not very polite to don't believe me and ask for print screen but here you have.
Give me also your open core EFI to see how you managed to have mic after wake.

very simple 

 

diskutil apfs listSnapshots /Volumes/BigSur 

 

diskutil apfs deleteSnapshot disk3s5 -uuid  ????????-????-????-????-????????????

Spoiler

 

 

 

 

You need to perform the commands in my guide from terminal, booted into Big_Sur Recovery or Installer USB.

 

From your screenshots, it is obvious that you are booted into the completed Big_Sur volume, not the Recovery/Installer terminal which has a bash prompt (also in Recovery, you are automatically the admin so no need for sudo)...

 

-bash-3.2#

 

PS Extra Info

As reported by @AppleBreak and confirmed by @ameenjuz, the "UpdateOptions.plist method" to prevent sealing of the Big_Sur volume has the unfortunate side-effect of later preventing the deletion of APFS snapshots from Recovery/Installer USB, throwing out "Operation not permitted" and "Insufficient privileges" errors.  Therefore if you want to prevent volume sealing and allowing access to Big_Sur volume from older macOS, I recommend using @ASentientBot's hax2 patched installer or interrupting phase3 installation method.

I booted into installer to run terminal from recovery. I had no issues. For me the surprise was I didn't even need to disable CSR

Sorry I didn't read when you wrote that you have installed on single disk, with your efi I had panic when I boot Big Sur, maybe for different cpu and display, I've i5 3230m and display 1080p, I've to fix this issue.

Regarding Multiboot on my laptop with your efi booting only with OpenCore bootloader, Ubuntu boot correctly but Windows 10 crash, I've try to format my disk and start from scratch, can you explain if you have installed before Big Sur or Windows 10.

I attach my efi folder.
