Will this fix my problem with personal hotspot on my iMac 2012 late?
No, honestly I do not know!

Please try to figure out if this is probably a problem seen on supported systems, too. Big Sur will have a lot of bugs and most likely we will see them on the unsupported systems as well. We will not fix such bugs... :)

I'm having an issue where my 2012 iMac 27" will not, after successful installation of the micropatcher, accept my password in Recovery mode (while it will in boot mode), so I cannot get into Terminal to apply the wi-fi fix patch. Without wi-fi, I cannot verify my password via Apple ID in Recovery mode, so while I've "successfully" upgraded to Big Sur, I'm stuck with no wi-fi currently. I've been combing through the forums but haven't found a fix. Can anyone suggest anything?
Turns out it was an issue with disk encryption. I was unable to turn that off (System preferences just ignored the request to do so), so I ended up doing a fresh install and following the instructions on the patcher website. This time I was able to get through step 15 and successfully install Big Sur. I hope this helps someone else!
 
Hello,
Does anyone know of a patch to enable Mojave under System Preferences - Startup Disk to see a Big Sur as a Boot drive?
On a dual boot Mac Pro with Mojave and Big Sur - Big Sur can see Mojave and Catalina on System Preferences - Startup Disk but not the other way around. Of course one can always hold Option after the chime at boot but was curious if there was another way around this without Opencore Boot Picker installed?

Can I use update macOS normally through system preferences with the update prompts after installing the patcher?
That really remains to seen , someone said no a new patch will be used for updates , but I just ran the updater and it checked for updates and then showed that my mac is up to date with 11.0.1 , it all looks normal , and I hear the beta is out of a developer download , so maybe when another official release that is not in beta is released for updating then will find out if it will update as normal
Someone did say they downloaded the beta 11.1 ver and used this same patcher and it worked , they showed pic as well

No issues. Micropatcher 0.4.4 with CoreBrightness added.

I had exactly the same problem. When I installed big sur under system preferences both disks were present and after start Mojave back up as startup disk big sur was no longer available

Updated from 20B50 to 11.1 build 20C5048l linked by @jackluke, on a cMP no issues at all with micropatcher v0.5.1. Same goes for my 2012 MB1 9,1. Have WiFi working on both.

I've checked briefly, most important feature request woul be a Softwareupdate fix for delta updates ofc. I remember with Catalina Patcher a fix came up after a few .xx point releases, still hope thats feasible. Also I'm missing Night Shift on the cMP but not the MBP. Just FYI @Barry K. Nathan, thanks for all you've done so far.

Now the longer version

This is for a 2012 Mac Mini and almost sure for the MBP from the same year, others, especially earlier macs need extra steps, for that read the manual on micropatcher page.

1. Have a USB stick handy, or an external disk, or a dedicated partition.
2. Download the full installer from here.
3. Download Micropatcher from here.
4. Open Terminal.
5. sudo /Applications/Install\ macOS\ Big\ Sur.app/Contents/Resources/createinstallmedia --volume /Volumes/Install\ macOS\ Big\ Sur\ Beta --volume /Volumes/***
*** is the disk label you install the Installer onto, so the USB stick, I dragged and dropped my USB stick onto the terminal, the path will be automatically added.
6. Input your password.
7. It will erase your disk so be aware not to chose the wrong one.
8. Input "Y" if asked to erase.
9. Wait until it's finished, could take a while dependable of what kind of media you use.
10. Unzip the downloaded micropatcher, drag the micropatcher.sh file onto the Terminal window, then enter.
11. In Terminal type sudo and then a space, next drag the install-setvars.sh onto the Terminal window, hit enter.
12. Restart after it is finished.
13. Hold Option key right after restart, keep holding it until you see the bootpicker.
14. Chose the EFI disk, it will instantly shut down.
15. Start up again and again hold the option key for the bootpicker.
16. Chose the USB installer, wait for the installer to open.
17. Chose the disk you want Big Sur installed onto.
18. Wait for probably an hour or so (Have a coffee or a beer in the meantime 🍺 ) if you install from a USB stick, probably half of that if the installer resides on a SSD medium.
19. Restarts multiple times.
20. Almost done.
21. The next step is for WIFI, Wifi does not work OOTB on a 2012 Mini or 2012 MBP....
21a. Restart for the last time after it booted into Big Sur, you may restart before login or after login, makes no difference.
21b. Hold the Option key again to get into the USB installer, there are other ways but this one is the easiest, chose the USB installer, next open terminal from the menu.
21c. Input "/Volume/Image\ Volumes/patch-kexts.sh /Volume/***" and hit enter, when finished enter "reboot", both without the quotes.
*** Is your disk label

Voila...done...a working Big Sur OS.🍺🍺

Edit: Do not forget to thank Barry K. Nathan
your steps are much easier to follow than the barrykns. get it installed on my MBP 2012 + WiFi fix.
 
I came across this on YouTube. The processes described here, in this forum are over my head. I was fine with dosdude's patches through Catalina. Big Sur, not so much. This video makes things seem simpler, at least for me. Will probably attempt in the next few days. Perhaps it can help others.

You can enable Night Shift and OTA upgrades yourself by searching this thread for posts made by @jackluke. We had a longer public conversation about OTA upgrades and the danger of getting unwanted firmware updates on this way.

Thank you./Hint 🤔 ;)

Dude I've been following this thread from day one, loong before you joined it and I'm aware of the BigSurOTAswufix. ;)

@jackluke you said that there is still work to be done, would love to hear about some progress in case I missed it. As for the integration of both into the micropatcher, Barry has mentioned he was looking into it also, and I'd think many would appreciate to see that coming with the kext payload folder. Thanks

The first sentence you claim to know everything from day one on and in the second you ask for more information in case you missed something - could not be better.

Progress could be made here if experienced users like you start to test such installations on their own before a patcher includes it and it may potentially cause more headache than good.

Finally this is just another request for a better patcher, there was a note on the first page about such requests. But you already know this, you have been following the thread from day one.
