[pre-release] macOS Big Sur

[SavageAUS]

[mention]eSaF [/mention] now I feel like trying more to get my Big Sur name back that Preboot stole. Mines a laptop so isolating disks is possible but a pia. Although I might be able to disable windows drive in bios hmmmm decisions decisions.....
PS laptop can take 2 x nvme & 1 x sata ssd

Well, well, in my before last fresh install I had BS instead of PreBoot, too and it fixed itself... after a while it changes for PreBoot... BS weirdness in all it's glory... LoL ...

Good day, is your Big Sur beta 3 allowing the AirPortAtheros40.kext, cause mine is completely refusing it?

Works fine on Big Sur Beta 3 here.

BigSur Clover KextInjection Package.zip

Sadly, those 3 kernel patches and cloverX64.efi don't work on my HEDT MSI X299 system. Stuck at "PCI configuration end, 11 devices" error

Seems like ACPI error. I tried to find PNP0C09 as per creating my own SSDT guide. But PNP0C09 does not exist on my X299 system. Anyone have pointers to fixing my ACPI for Big Sur? It did boot perfectly via Clover on Beta 2.

Using new OpenCore 0.6.0 Beta Release (24/07) + Latest Lilu and his plugins:  I can't boot Big Sur. Stuck at apfs_module_start: 2411 (with or without apfs.efi, with or without SSDT-AWAC.aml

 

Any ideas ! Please.

 

Dont' forget to add vsmcgen=1 to boot-args, if emulated SMC is detect as MMIO.was working in beta 2 with virtualsmc of course)

I got same issue with 3 hacks of my signature.

 

Fred

J'ai eu le même problème que toi avec les 3 hack de ma signature.

Ils sont détecté par VirtualSMC pour utiliser MMIO.

If faut ajouter à boot-arg vsmcgen=1

I get this stupid issue "Couldn't alloc class "AppleIntelPchSeriesAHCI"  " with OC and Clover 5120.

But Clover 5119 mod pass this issue.

Hi! Does anybody have this phantom GPU on BS beta 3? It happen in 2 of my hacks (ivybridge desktop and laptop).

Would you please share your EFI folder for your IvyBridge desktop? I wasn't able to boot mine with OC. You can remove the SMBIOS info from config before sending it.

 

Thanks

 

P.S.

About the phantom GPU check if there's an entry under DeviceProperties.

@iCanaro  thanks for the link ! 

 

I finalize the installation of my hardware and make bios adjustments and after, let's try...

May be you find this on RTC for X299 : 

 

Device (RTC)
                {
                    Name (_HID, EisaId ("PNP0B00"))  // _HID: Hardware ID
                    Name (_CRS, ResourceTemplate ()  // _CRS: Current Resource Settings

Take a look at your DSDT

There is a way with opencore to disable the boot log text file in EFI folder every time I start a PC

Here you have. If install, disable unnecessary kexts. Especially wifi and bluetooth. After that I have no problem. Even recovery boot easily. If continue not booting, tell me symptoms, maybe I can help.

About phantom GPU, it's kinda strange:

@eSaF maybe if you install it with SIP disabled, the Preboot issue does not occur....? I don't know... I installed with SIP enabled (in order to see the update in System Preferences; by the way, that seems to be another bug) and I couldn't get it to show anything other than Preboot ever since. No matter if SIP is enabled or disabled. If you're doing it after the fact, it doesn't seem to change anything.

 

Also, I don't know why, but I can't seem to be able to disable SIP from Recovery. It says it's disabled and I have to reboot to see the changes, but...it's still enabled (if I left it enabled) when checking its status via: "csrutil status". In other words, no matter what you do in Recovery, doesn't seem to affect the live system. But I'm probably missing something... There are a ton of new things with Big Sur, so I wouldn't be surprised if this was yet another bug.

 

 

Same here, bud. 

it doesn't matter what I do in Recovery, after reboot "csrutil status" shows enabled. 

I tried to reinstall BS from Recovery but Preboot is still there. On top of that I lost Big Sur from Startup Disk, lol.

Hi Folks, I am running Big Sur Beta3 no problem.  Reverted to FakeSMC (vs VirtualSMC).

It may have been posted in this forum already, but I may missed it.  I need to mount my root partition as read-write, but I'm getting error 66 (I didn't have this issue in Beta2).  This leads to my second issue which is I can't boot the recovery partition using the latest beta of opencore 0.6.0.  It refuses to boot and dumps me back out into the opencore picker.  So to summarize my issues with Beta3:

 

1) Trying to mount root partition as read-write but getting error 66.  I've tried different values of csr-active-config (verified that they're enabled using nvram-p).  I've tried FF0F000 per the latest dortania, 77080000 as I've seen some mention before, and the old E7030000. None of which allow for me to mount my root partition as read-write.  I'm booting using kernel collections method (and not the booter-fileset-kernel + booter-fileset-basesystem method).

 

2) Given the difficulty in #1 above, I then tried booting into the recovery partition, to run csr-authernticated-root disable command.  But opencore isn't booting the Big Sur Beta3 recovery partition on my rig.  Some OCD error or something of the sort.  Opencore doesn't seem to be able to boot the Big Sur Beta3 recovery partition.

 

I'm stumped.  Might someone have any advice please?

 

Thanks!

For #1, I don't know. But I think I can help you with the second issue.

 

Set JumpstartHotPlug=YES in OC config.

I have been attempting BS3 all this while with OC 0.6.0 and failed, but now after seeing people having success with Clover (have been a long time clover user)

I thought I will give a try at BS3 using a bootable USB and Clover.

But I am stuck at this point

I remember in the past that under quirks you need to enable AvoidRuntimeDefrag to get past this, which I have done but still no luck.

Anyone any clues?

 

Here is my EFI if anyone want to take a look at EFI.zip

 

Hi my friend!! Maybe you should try -wegnoegpu (for AMD Gpu) or -igfxvesa (for intel igpu)

Thanks for share...

Hallo @Matgen84 you write ob top "EDIT I forgot a '>' in the config.plist. I can boot with FakeSMC now.... and here write you not work...

what is can you boot after the Error "apfs_module_start: 2411" ....with FakeSMC in Open Core or not ?

Thanks!  That flag worked, and I can boot into recovery finally.  But even though I run 'csrutil authenticated-root disable' in recovery, I still can't mount my root partition as read/write (i.e., sudo mount -uw /).  Still get the Error 66.  Could it be the wrong csr-active-config flags (FF0F0000) are set? 

 

Does anyone know how to mount the root partition as read-write in BigSur beta3?

@AlfredoM you mixed up many of my comments. Which makes your question unclear. I confirm Fakesmc can replace virtualsmc in Opencore. If you've the same issue of mine.

Well, I tried this...and it seems to work. As in, you can mount the partition and add stuff to it. But I don't know if this is the right way to do it with the entire snapshot feature in Big Sur.

 

But...if you wanna try, you can do this:

1. set csr-active-config to FF0F0000 (or 77080000; seems to do the same thing)

2. reset NVRAM in OC boot picker

3. boot into your system

4. open up Disk Utility and select Mount, then "Show in Finder" (from Disk Utility) for the system partition of the booted volume.

 

See if you can modify anything in there.

I created a new folder in /System for example.

 

 

Spoiler

 

Again, this might not be the right way to do it. But if you're working on a test partition, I guess you could try.

Try VoodooI2C.kext.

 

@crazybirdy It may also be that you are not getting any kext injection.  I had that issue with Clover 5120 but did not have it with the modded 5119.  A more recent build of 5120 resolved that for me.

My experience with creating a Big Sur beta 3 USB installer

My USB installer is simple.

NOTE - Latest OC and kexts worked, OC and kexts, updated 07/24

 

ACPI

* SSDT-EC created from OpenCore guide

Drivers

* HfsPlus.efi <- not sure this is needed anymore

* OpenRuntime.efi

Kexts

* Lilu.kext

* WhatEverGreen.kext

* VirtualSMC.kext

* IntelMausi.kext <- your Nic kext may be different

config.plist

* this is where you follow the guide, trail and error here and you must document your changes so you can go back if you break it

 

This was created for the HP 800 G1 but will probably work for most Haswell systems.
