I have installed Big Sur using Ben Sova's patch in my mid 2012 MacBook Pro with SSD and 8GB RAM. I am using the eastern holidays to put all to work again. I used an abandoned Catalina to upgrade since there is no support to clean install yet (there is a workaround but I decided for the default path). It's working nicely! As long Catalina have been improved - it's now more fast and stable - Big Sur runs better. So that's my personal report: it works, and works better! Just need to be sure the Mac have Metal support, a SSD (I doubt will work with HDD) and good memory.
Also I might open a new thread about Catalina...

Thanks @air.man, I have now also tried with most of these patches. When restarting with [Option] key pressed I thought to myself why not try to boot from the "EFI Boot" volume, that surpisingly (at least to me ;-) did work. But if I try to boot from the "Big Sur" volume, it still crashes.
Maybe I have to also use OpenCoreAPFSLoader, as you wrote.
I tried forcing it with Pacifist and same problem; as soon as that kext is in /Library/Extensions/, the Mac won't boot.
Is this a function of OCLP or a problem with the kext?
Mailed HighPoint but Easter delay so nothing back yet.
OCLP shouldn't interfere unless the kexts were unsigned, as we do enforce SecureBootModel policy and System Integrity protection. So the process of installing a kext should be the same as with a natively supported Mac with proper security enabled.
I would recommend asking HighPoint whether their notarization system with Apple is still functioning correctly. Otherwise you could try disabling SecureBootModel(and maybe SIP) via Patcher Settings, rebuild OpenCore and reinstall it to the drive and see if this changes anything
Thank you for your advice khronokernel. I'll wait until Highpoint comes back with an answer. Then maybe 11.3 Final will have been released in the meantime to try your suggestions if Highpoint says their text is properly notarized.
I can live with a bit of fan noise in the meantime!

my mistake yes the display port is broken for some time but I used the HDmi for the second monitor and it always worked. Now I find myself only a dvi that works for the main monitor and that's it
Hello!
Sometime ago I updated my modified 2011 iMac 21.5" to BigSur using @Barry K. Nathan micro patcher. Now, I would like to upgrade it to the latest version WITHOUT erasing my drive. How can I acomplish that? I'm asking because I want to be 100% sure what I am doing. Some kind of guide would be much appreciated!

Just download the latest full installer, prepare the USB stick as before and install Big Sur onto the the very same partition you have your old Big Sur installation. This procedure will not overwrite any user data or settings and it is the way Apple updates using a full installer worked for years, now.
Since you have to use OpenCore to enable brightness control you can also use the iMac micropatcher or OCLP to get things done.
The only thing to avoid in any case: Do not delete your existing Big Sur partitions, just install the new version onto it!
Thank you! I will try it immediately! But I think I'll skip any OpenCore related stuff since I don't really mind not having brightness control.
Having the backlight burning at 100% is just a fast way to end the lifetime of a nice 2K LG LCD panel. OpenCore offers OTA upgrades, but you possibly do not mind about that, too.
Just to clarify, my MBP model, 9,2, one of the few that is exactly in sync with OCLP, I don't have to update any kexts or anything right? like the people that are talking about updating kexts are only those of whom's MBP model's aren't compatible with some functioning, hence the availability of the kext patch. If everything is working, I should just leave it be, correct?
Anyone know why I am getting this error? I’m using the OpenCore Legacy Patcher. It has been sitting like this for over an hour now. It was stalling on the apple logo with the loading bar so I enabled verbose to see if I could see what the problem is and that is what I see. Any ideas? I have 2013 iMac (iMac14,2)

Thank you to all who make this forum work! Here's some nostalgia to remind us how far we've come: 10.3 to 11.3!
Just noticed, I have updated Virtual SMC, Lilu and Whatever Green kexts on my Clover Hackyintosh and noticed that there are two receipts for the latest updates of MRT and XProtect . I wonder if they are damaged. I hope not, if they are, I would need to re-install the OS. The updates were installed on April 1st , via Silent Knight, I remember.
OpenCore Legacy Patcher v0.0.20 is out!
The main benefit of this release:
- Resolves output regression on Mac Pros compared 0.0.19
- Resolves bluetooth support for stock BRCM2046 chipset in older iMacs
- Fix UGA-based hardware support on UGA-based hardware(ie. iMac8,1, MacPro3,1, etc)
- ie. OpenCanopy GUI support
- Shrinks .app size by 1/5th, as larger Apple binaries were moved to dedicated repo
Hope everyone enjoys the new release!
Edit: Due to a small issue with images in OpenCanopy, 0.0.21 was released. All benefits of 0.0.20 still apply

Tank's alot Krono now finally i've my macpro 3.1 run with a second monitor and all is ok wow it's fantastic
Nope. The OS is patched using what is discussed in here. I have had some issues in the past, on Catalina, with macOS patched, on updates of these sort.Wrong thread, I suppose
Hi khronokernel. I tried disabling SecureBootModel and SIP via Patcher Settings, rebuilt OpenCore and reinstalled it to a formatted SSD and although it did not KP at the package validation stage this time it still cannot reboot—the progress bar gets half way and stalls.
I checked the package with Suspicious Package and it is notarized, so it looks to me like HighPoint needs to update the package in some way for 11.3 beta 6.
I also have iMacs in late 2013 (iMac 14,2) but that's okay for me.
I am using all versions of OpenCore Legacy Patcher and today I put OLP 0.0.22 Build; all the latest Builds have no problems with our iMacs.
Did you accidentally change the options while creating the EFI Build?... You don't have to touch them if you have an iMac in late 2013!
Note. Using the OLP options I just disable the OpenCore screen when the Mac starts up and also edit the config.plist file to reduce the timeout from 5 to 2 seconds ... But I only do this for nitpicking
and to see the Mac start up as if it were a Mac supported by Big Sur. But don't do it, unless you have enough experience.
Installed 11.2.3 on a MBP5,2 with OCLP 0.0.21.
Smooth installation, booting, running on this LegacyUSB machine which now "feels" like a MBP11,3 as intended.
Clean installation on an external (USB) SSD. Migration assistant done OK.
OCLP is on a USB pendrive made from Catalina.
Installer made with createinstallmedia from Catalina, also on external (USB) disk.
Verified that I can boot back to Catalina which is my production system on internal SATA SSD.
Thank you!
Next step is to update OTA to 11.3b6, and more tests.
(as always of course, no graphics acceleration on BS).

If you follow this Apple instructions there is only a single installer image working on both platforms...on the first post of this thread (always a good start to read before posting) there is another tool named gibMacOS linked in which you can use to download all available installer files, not only the most recent.
Hi! I listened to you advice and I installed opencore and enabled backlight control. I used your guide and your iMac micropatcher. Everything works great and I successfully updated my system. But I have two questions: where I can find a guide on how to install open core on efi partition so I don't have my usb stick for my system to boot? And what are OTA upgrades.
