I should be clear I ran those commands from Big Sur installer after it had already installed and everything works but wifi. Any tips or tutorials would be awesome on public beta 1... Thanks!
Got a tip for us?

I have seen this several times, too! So I would call it unwanted but normal right now. Since I got a usable installer one could ignore it.
macOS 11 Big Sur on Unsupported Macs Thread
MBP mid 2012 (BigSur was installed, could not update directly, could not select any drive - Error:Update can't be installed and later BIdomainerror 3) Connected via Ethernet during the installation process Used the terminal to run all commands/scripts Booted into BigSur Build 20A4300v...

I just did a fresh install with the latest patc
my fresh install is in a boot loop. In verbose mode it gets through everything fine. It’s when the Apple turns white and the bat loads a little bit and then it reboots. Iv gotten past it before. I’ll let you know what I do.
I couldn’t mess with it anymore last night because it was movie night and the other Catalina drive has my plex server on it ☺
EDIT: I also noticed while I’m booted into Catalina, I don’t see the ‘UPDATE’ volume only the Big Sur volume.
i mention this because usually I see both
Usually that means your SIP not disabled
Then create a patcher for my evil Mac mini 2010 (Macmini4.1) I'm unable to get internal sounds and ethernet. I'll try your
Some tips: With Penryn, I must skip stage 3 installation to avoid error 66. But I cannot boot on Bigsur on external hard disk (It is shown only BigSur - data of internal SSD installation) and I can remove telemetry & do FIRST boot (before prekernel patching) only using @jackluke OpenCoreLoader4, also starting installation with @Barry K. Nathan patcher 0.0.20 . So I'll retry with Beta 5 on SSD (Aug 18)

It would be more interesting to know what you did before you made it to this situation.

It depends how do you installed BigSur because there are many methods that used different ASentientBot Hax.dylib, and which bootloader are you using for example opencore or refind, anyway try booting targeting your "BigSur Data Label" or its "Preboot" , with CMD+S , then from single user mode type:
Code:
mount -P 1
mount -P 2
mount -uw /
kmutil install --update-all
kcditto
exitand you must have
csrutil disable from macOS recovery .Anyway you quoted an incomplete part because these are the steps I written:

there are many other commands to use before the apfs_systemsnapshot .

Many thanks for trying to sort it posted those log files their in page 123 post 3063
As far as I can tell it says the install succeeded, I’m lost with it doesn’t make sense beta 2 installed no problems at all
That was using the parrot geeks method
I see both on the drive with beta 2 if I try to update it and on a Catalina desktop it’s labelled as update but on a fresh install I see nothing. In disc utility it reports the drive as “installer” and is not mounted if that helps at all

boot into your Big Sur Usb installer in the terminal enter nvram boot-args="-no_compat_check" and csrutil disable

If you have a BCM94360CD, downgrading /System/Library/Extensions/IO80211Family.kext to the Catalina version will fix that. Copy it from Catalina to a usb memory stick name Untitled and use these commands while booted under Big Sur...
Code:
mkdir /tmp/mntpoint
sudo mount -o nobrowse -t apfs /dev/diskXsY /tmp/mntpoint
cd /tmp/mntpoint/System/Library/Extensions/
sudo rm -fr IO80211Family.kext
sudo ditto /Untitled/IO80211Family.kext IO80211Family.kext
sudo chmod -R 755 IO80211Family.kext
sudo chown -R root:wheel IO80211Family.kext
cd ~
sudo bless --folder /tmp/mntpoint/System/Library/CoreServices --bootefi --create-snapshotwhere diskXsY is whatever mount shows for the mounted root snapshot (disk7s5 for disk7s5s1 for example). After you reboot, wifi should work.
2012 there is no need to leave SIP disabled.
here everything is activated as if it were a supported mac.
only parameter is NVRAM
Hey, @TimothyR734 did you tried to install Big Sur on your iMac 9,1 or still waiting?
I just realize that you've asked me about this #LOL
Yeah, on an Arrandale laptop with i3-370M / Clarkdale I tried BS DP1-PB many times with no luck. It got KP with AppleACPI* IOPCI* AppleSMC* dependencies. Though, using Catalina's prelinkedkernel bypass this issue but another Panic occurred.
for those with Mac Pro 4,1 flashed to 5,1 with successful beta 4 install.....recommendation would be to swap out the old wifi card.....to be honest these guys have been working hard for years on these patchers including Dosdude which I am eternally grateful for....If your your gunna upgrade when the final hits gold do yourself a favor and upgrade your wifi card. Its simple and its cheap and it means an almost fully working bigsur system. It will also take a complication out of the equation when updates come out after it hits rtm/gold
