Dosdude1 patcher has example code using NSTask and NSPipe.
boot-args fix by joevt · Pull Request #103 · dosdude1/macos-catalina-patcher
Here is a change that helped me update Catalina to 10.15.7. The patch does not replace boot-args NVRAM variable. It will append to it or create it if necessary.

We got an old 2012 27” iMac that isn’t officially supported. I have to open it up again to install a bigger SSD. I was wondering if anyone can recommend a WiFi card that would work from the latest iMacs? I’m assuming since some people only have wifi issues with their 2012 if I upgrade it to the latest it could support it would fix that problem right? It would also just work if it came from a newer iMac ? I’ve tried researching but I can only find the same models or possibly the 2013 version? Thank you.

my experience, Mac Pro with opencore is perfect, refer below for more information:

I created a new "easy to install package" as per many requested (based on the official OpenCore). [The attached package updated to 0.7.9] For those who only need HWAccel, post #594 has everything you need. This new package mainly offer HWAccel + boot screen. Also, this package should work in...

For others, please gen your own serial number and UUID when use the above code.
Hundreds of people using the same serial number to login to iCloud may cause unexpected issues.
Even using your original serial number (which not belongs to this Mac model) still better than using this published number.
Yeah, micropatcher....
Not getting up «install macOS Big Sur», just efi boot... hmmm I’m not using beta, I’ll try that instead. Thanks
Posting your S/N publicly is a bit dangerous... For codes you could apply the “code” function.
The USB installer, prep correctly, would show up with 2 things on Option Power up.
(a) "EFI Boot"
(b) "Install macOS Big Sur"

Serials and UUID posted, was generated randomly by OpenCore Configurator........ 😎😎😎
Once again, stop saying a method is all around safe. Your case is your case, but its not the rule. The simple answer is no. The fact is OpenCore is bricking a certain percentage of machines, particularly MBP's, MBA's, and iMacs from 2012-2014. Until the firmware issue is remedied with a standardized and repeatable solution, saying anything to the contrary is dangerous. Those coming to the forum asking for information and help will be met with only half truths, and that's setting them up for failure.
And the full answer is it entirely depends on how you want to go about updating. For the Mac Pro I would say its relatively safe, even doing an OTA update. Theres little risk of a firmware issue. For the MacBook Pro I would be more cautious. My advice would be create a full USB installer for the time being and install that way. It may be worth considering the Micropatcher. Avoid OTA's for that machine entirely until the firmware issues get worked out.

Format the USB drive, and set up the install again. It sounds like an issue with either the USB drive or createinstallmedia didn't complete. It will not matter whether its a Beta or Official release. Just do it again following the instructions closely. Heres a quick Reference Guide for the MicroPatcher:
1. Run Create Install Media
2. Run micropatcher.sh
3. Run install-setvars.sh
4. Shut down and select "EFI Boot" (the system will shut down)
5. Reboot, then select "Install Mac OS Big Sur"
6. Kext Patching (if you need it)
Ok, but how would I make that visible in the GUI? Here is an example of my running a script:Dosdude1 patcher has example code using NSTask and NSPipe.

Hi Jackluke, have you been able to run BigSur on your old Macbook Air mid 2011? (MacBookAir4,2).
I will screenshot the process, it used to do so - when creating boot volumes before, but didn't this time.... will get back to you after xmas
- and happy hollidays everyone
yeah what I did,,, but will document the process after xmas
maybe you guys will spot where I go wrong. Anyway, happy juletide Happy Holidays @dosdude1 @jackluke @ASentientBot @Barry K. Nathan @parrotgeek1 Thank you for your valuable support as ethical hackers of Big Sur! My perfectly working iMac 2013 with masterfully patched Big Sur logic board is dead, ONLY due to a killer USB 3.0 7 ports Cinese Hub (according to Apple Store support, a damage of 600€!) so I have bought a Mac mini M1 that's incredibly fast and surprisingly compatible with Mac x86 and Windows 10 ARM x64 Insider Preview apps thanks to Rosetta 2, Parallels Desktop M1 16.3 preview and some very useful tricks that I have learned IN THIS FORUM
But I will continue to follow this trend hoping that one day my Mac mini 2010 Core 2 Duo Penryn will have accelerated graphic on Intel Big Sur.
