You are really good at this. A suggestion make a video on youtube would really help audio visually. Cheers ✌️
Thanks, I am not a native speaker and I am the visual learner by reading
So I never understood why wasting time in front of a 15 min video when I am able to gather the same information within seconds of reading. This is just entering some lines of commands and doing 10 steps in the way @Barry K. Nathan documented it already.But I promise to create a more complete documentation of the things we (@highvoltage12v and me) are doing here later. Right now I just want to make sure that the patcher developers add the patched extensions we provide here to the Big Sur patcher or they may offer an interface within the @dosdude1 patcher to integrate new hardware configurations. In this case I could add the patch sets for the part of the community owning a hardware modded iMac 2011 with a metal GPU - just writing from my 2011/GTX 780M/BCM94360CD using Big Sur.
The message I can send right now is:
Replace the GPU and the WIFI/BT card and you will get most likely a Big Sur compatible platform. This config is close to the 2013 iMac models and may have ever a better GPU (AMD Polaris). And if runs really perfectly with Catalina as of now.
But Apple may find a way to lock us out in the last moment. Who knows..
i dont think so, i will try ist again
Check the first post before asking questions please.
I have a 2013 Mac Pro and an unsupported 2012 Mac Mini. Is it possible to install Big Sur on an external SSD using the Mac Pro, then boot from the external SSD using the Mac Mini?
*If* you own a thunderbolt 2 cable you can put your Mac mini in Target disk mode and install directly to a partition onto the mini.
You "can", but non of your features will work, such as WiFi, sound, sleep, etc. You need to install the additional patches to make it "fully" work
Why not install directly from your 2012 Mac Mini?
Exactly! It'll not make a difference if you install it on your 2013 Mac Pro. It'll save you pain to just use the BarryKN micro patcher on your 2012 Mac mini and you'll be all set!
Hi Everyone,
I searched the thread for the terms `BIErrorDomain error 2` and couldn't find any information about my problem.
I recently upgraded my MacBook Pro 10,2 (Late 2012) from Catalina to Big Sur and it was a success.
I then tried to upgrade from what i remember was beta 2 to beta 3 or 4 and that's where issues started. I can't remember what exactly i did wrong, but each time i tried to boot i would get a forbidden sign.
I did some research and I fortunately could restore my system to Catalina by downloading restore tools (Option+CMD+R) from Apple server.
Installation worked perfectly, and i could use my mbp again.
Of course : I want Big Sur and not Catalina. But before i try again to upgrade, i create a new APFS container to have a Big Sur 'partition' and a Catalina one (just in case).
I then proceed to download Beta 6 > createinstallmedia > ran micropatcher.sh from barrykn > Boot from USB > set-vars.sh > Try to install Big Sur to disk.
From there i can't go further. I can't upgrade Catalina to Big Sur, i can't install it to the 'Big Sur' apfs container and i can't even install it to an USB APFS Partition i made (I knew it would be slow but it should at least work).
All disk are greyed out, with error 'Operation couldn't be completed (BIErrorDomain error 2).
I tried everything i could, to re-create disk, create a 'real partition' (instead of APFS Container) : nothing work since i had the forbidden sign problem.
Hope someone knows the answer to this.
Thanks a lot guys.

I have a Late 2013 27-inch iMac and I ran into a similar problem when I tried to upgrade from Big Sur Beta 4 to Beta 6. I had successfully upgraded from Catalina to Big Sur Beta 1 to 2 to 3 to 4 with no problem. When trying to go from 4 to 6, I too kept getting the BIErrorDomain error 2. The only thing that ended up working for me was formatting my iMac HD and doing a fresh install of Beta 6 (then restoring). I thought it was an issue with running the
set-vars.sh at first, but I know I did that part correctly (eventually). Since you have a partition, I would think it would work the same as a disk format. Are you positive the set-vars.sh are working? I had a path issue once booted into the installer, so I had to type:/bin/bash /Volumes/Image\ Volume/set-vars.sh
I'm positive the command works as it shows messages to the screen confirming that nvram / csrutil commands were run successfully. Anyway, I added the -v parameter, and then, booting Catalina indeed shows boot logs so i think the command is working correctly
I tried your command (adding the /bin/bash at the start) but it's unfortunately the same :/
Thanks for your answer
EDIT : So actually running /Volumes/Image\ Volume/reset-vars.sh, rebooting, then set-vars.sh fixed the problems ! Never tought it would work. Honestly tought re-running set-vars.sh each time was enough.
EDIT 2 : So i tought it was good. Even though i can actually launch the Big Sur installation, after the first reboot it nows shows a forbidden sign instead of continuing the Big Sur installation... damn.. Tried the installation on two different disk and got the same issue

Have you noticed that the Internet is very slow in Big Sur Beta 6 or is it just a matter of my connection? (MBP Mid 2012)

Funny you should ask. I wanted to organize a list and maybe have that as a sticky. Didn't finish, but I do have the first 5 and the post they are mentioned in.

Hey guys, I will try it on my Late 2010 MBA 1,6 GHz 4 Gb NVIDIA GeForce 320M 256 MB
Good Luck
If you manage to enable internal sounds and graphical acceleration (dock transparency) let me know how.
It's most likely due to the no compat check, try to run that command in recovery.
You'll might have to start all over again though, but try before.
Run
sudo nvram boot-args="-no_compat_check"
in Terminal in recovery mode.
I was able to install macOS Big Sur using the micropatcher v0.1.0 on a external SSD connected to my macBookPro 2011 8,1 and got it running!
WIFI, sound, FN-keys (volume, brightness etc.) working!
It took me around 3/4 hours from scratch and I used mainly the receipe on github and some comments in this thread.
You done a amazing job @Barry K. Nathan !!!
Let's get further and further --> I need another partition on my internal SSD for Big Sur

Hi, thanks for your answer, booting with Cmd + R and Typing the command indeed work ! Finally running Big Sur again !
Additionnal info : 'sudo' doesn't exist in Recovery mode, but the command work without sudo
Can I delete the Big Sur volume called install Mac OS beta and have bug sur still work Bc i portioned half and half and I want the rest of the room for Big Sur
I took my USB external hard drive that has Mac OS Big Sur Beta 6 on and booted up on on a mid 2011 MacBook Air and it booted just fine the only thing is the background of the dock is black but dose not look too bad, I just wanted to see if it would boot and it did really did not spend much time testing it
