I really want to point something out to everyone outside of 2012 machines....these methods are not fully supported. better support may come with later versions of Big Sur. Right now those of us installing Big Sur are exploring the unknown like humans always have... .Honestly those who don't want a lot of work as updates are released.......simple.....Wait as Big Sur comes out with more updates this community will become stronger. Remember no graphics acceleration for none metal graphics cards at all like we had in Catalina. Catalina has two or three years of support remember that before you hit install its not a bad thing to wait! Big Sur will be here with a much more matured community. Like climbing Mount Everest or venturing into space everything happens one step at a time. Although we are not making history today 100% we are in a way keeping hope alive for those who don't have a lot of money or those who love exploring the unknown. Like I said Big Sur will mature and so won't we as a community! Those who have developed these hacks deserve our support and our feedback. Thats what makes this community so great. In a time of uncertainly we all stand to help each other and that is special from what ever country you come from.. .Today as a forum we are not bound by color or race or the hatred we see on tv we are nerds on a mission and that's special. Thanks for everything you guys do. Im greatful this thanksgiving!

I successfully installed Big Sur on my 2012 Mac mini. The installation went without a hitch following justperry's instructions in post #6011, but I had trouble with the WIFI setup. The first two commands in barrykn's list did not work for me, only the third one did, or maybe it was the second.

I have Big Sur installed on a separate 250 GB SSD that I just installed physically into the Mac mini. This way I can move back and forth between Catalina and Big Sur and experiment with Big Sur updates and still have a backup drive if and when Big Sur breaks down.

So far Big Sur runs very well on my machine, but I don't see much material improvement over Catalina. To be honest, the only improvement since High Sierra that really mattered to me is dark mode.

I have to say that the 2012 Mac mini, which I paid $800 for in November of 2012, is an amazing machine for serving much like a new product with some minor upgrades 8 years later and with an OS that isn't supposed to work in it!

Much thanks to barrykn and justperry for making this happen for me!
 
Hello everyone! The great-is news about my patcher(ish) is here!
I would like to let you all know that my friend, moosethegoose2213 and I have been working on an automator for the BarryKN micropatcher to automate steps 1-8. In a single shell application, it check for a macOS Big Sur installer app, checks for the BarryKN micropatcher on your desktop, and runs steps 1-8 of the micropatcher automatically. If it doesn't detect these files, have no fear! The app will automatically download the latest beta or release (depending which app version you use) of macOS Big Sur AND the latest version of the BarryKN micropatcher. If you do wish to beta test, we encourage you to give feedback on the functionality, as well as whether or not it works. We hope that we will enough testers to quickly release the official version. Unfortunately, at this moment neither of us are able to successfully patch a USB installer (if anyone has any tips help is appreciated), but we hope that in a future release I can develop a SwiftUI post-install to automate pretty much the whole entire process. We invite anyone who wants to test, and are very excited to put this patcher into action!
Here is the link to the package for our beta release:
 
By the way, my new project with this new automator is to create a post-install with swiftUI that will automate the post-installation of Big Sur. The hard part is with patching the installer...

I am completely lost with Bigsurfixes of Jacklukem, I created the bootable usb sticker with big sur, I applied fix 1 and 2, but on the installation screen I don't know what to do, if I apply the fixes, if I go first in hax3 fix installer, I'm completely in doubt, the disc is formatted, it's an iMac Late 2009 10.1, please help!



I made a video below using the BenSova patch on the MacBook Pro 2012 and posted on youtube, but I'm lost with the iMac 2009 on the Jacklukem Patch

Tried using the StarPlayerX BigMac Big Sur patcher as recommended in there beginning thread for my Mac Pro 3,1 with Nvidia 680 card (flashed). Ran the preinstall script, ran the Big Sur installer to my 500 GB SSD destination (internal drive), it rebooted again and again (expected). When I stopped it, it rebooted into the installer and seemed like everything was going well.

But when it finally rebooted again, this time back to my Catalina main boot volume, it couldn't do the "bless" option in the post install script. There is a volume as part of the SSD called "Update" which has a bunch of stuff on it that I wasn't expecting.

What did I miss here?

For those of you still wondering: No, unfortunately, I will not be making a Patcher for Big Sur, for the following reasons:

- Achieving full graphics acceleration with a non-Metal GPU has so far been unattainable under Mac OS Big Sur. As such, any machines that have a non-upgradeable, non-Metal GPU (such as 2011 and older MacBook models) will not be able to run Big Sur at a usable level. While I could make a disclaimer about this on my webpage and/or the tool itself, I know from experience that the vast majority of users will ignore such a warning, and then message me asking why their machine is running like complete garbage once installed (the post above mine as a prime example).

- The tool would need to be almost completely re-engineered, due to the completely different installer implementation Apple has done for Big Sur. While this normally wouldn't be a problem for me, it does take quite a lot of time to produce something that looks nice, is user-friendly, and works relatively reliably. Unfortunately at this time, due to other projects and obligations, I don't have quite as much free time as I used to.

- There are at least a few other Patchers developed by other people that work very well on the machines that I would support if I were to make a Patcher of my own (2012/2013 machines, and older models upgradeable to Metal GPUs only). An additional patcher would be redundant, as it would not offer any extra support than what is available in other Patchers.

With all that said, I will most likely make a patcher for the next major version of macOS released in the future. After developing, maintaining, and updating my patchers over the past 4 years, I really just need a bit of a break. I apologize if this is disappointing news to some, but don't worry, there are many other talented developers working on Big Sur patchers, and I can assure you that you won't be let down.

Completely understand. I am very grateful for your patchers in the past and completely understand you wanting to take a break. Thank you for all the work you have done for this community!

First of all I would like to thank you for the Catalina patch, forgive me for my bad English, but you helped to make my iMac Late 2009 survive, for me it is an honor to have a comment from you mentioning my comment, I understand your position and agree, Big Sur at iMac 2009 does not have a good experience.

Thank you dosdude1, all your work here is very appreciated, and it is good to hear from you, as always. I believe that no one has ever matched the thoroughness and near-perfection of your patchers. Your presence here was a blessing, and I wish you the best in your life. I am pleased to let you know that I am getting closer to cracking graphics accel on pre-2012s, but the chances are still very slim. Please keep in your mind that your actions will never be forgotten in this small, yet warm community. We wish you all the best!

Joking of course. Thank You for all you've done.
