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?

Ok, so what OpenCore should I install on my MacBook Pro 9,1?

EDIT: I tried 0.6.3 but that didn't go well... mbp9,1 booted to a black screen. I have macOS Catalina 10.15.7 ATM...

Hi guys,

first of all many thanks to everybody for this great work. Without you I never could install Big Sur in my iMac.

On saturday I finally installed Big Sur on my late 2012 iMac.

Everything works great, except my instant personal hotspot. I already searched this thread but didn't find a solution. Sorry, if I ask again.
I can see the hotspot in my WiFi status. If I select it, I can see, that the hotspot is activated on my iPhone. The switch toggles instantly and WiFi switches to LTE. But then I get a message on my iMac that the personal hotspot could not be activated.

On my 2015 MacBook everything works fine.
I tried two iPhones and two users with different iCloud accounts. Both with same result.

Is this problem already known and is there a solution for this problem?

Many thanks for your help!

Last night I recovered my latest Catalina backup. After that my personal hotspot connects instantly.
It seems that there's still a little problem with WiFi on an iMac 2012 late.

Another interesting thing. I installed Big Sur last saturday. The last days there where several backups made. While recovering I recognized that macOS should be 10.15. All last made backups are listed with macOS 10.15 even those which were made with Big Sur. How can that be?

Hi people

Since I'm in a third world country, my internet connection it's about 1mb-2mb... so wish me luck downloading.
Anyway, in the meanwhile I want to download the final version of the supported running OSs from my current unsupported.

This, it's to try what I have read since post 1, but... again... 1mb it was sad to try every beta.
So, I'm searching the
OS X 10.7.5 (white Macbook)
OSX 10.13.6 (for Mac mini mid 2011)
and
os 10.15.7 Catalina... current... I guess won't be more upgrades. MPB13 mid 2012.

I mean, I have the original and the final combo updates, but I know they have the complete install and I can't find in App Store (and I deleted the OS X Lion by mistake purchase that ame with mi Mini)

That you very much!!!!!!

I’ve tried what you’re suggesting at least 10 times with different scenarios with CCC but it always fails at around 52% of the operation. Only succeeds if the disk is not a RAID member. Send a screenshot showing you’re running BigSur off a RAID array. Otherwise, Your answer is a total BS.
boot off catalina dosdude usb. run the disk utility. delete existing raid. launch raid assistant. select (2) internal hdd which are now blank because you deleted the raid. create raid0 and select HFS+, GUID for raid set. inside of the raid0 set create an APFS partition. clone usb drive to raid0 APFS container. sometimes i use disk partition by clicking on the raid0 apfs container and select restore and choose the usb drive. sometimes i use CCC for cloning. bless failed error message but DOSDude APFS loader sees the RAID0 APFS as an internal HDD. reboot after clone and give it 1 minute to detect and boot. there are other ways to do this which require more terminal commands. google raid0 catalina boot drive and a bunch comes up. good luck!

Is anyone else having trouble with video playback in the TV app? On streamed videos It will play a second or 2 of the video and then just drop back to the main app screen. For downloaded videos in my library it is audio only and black screen. This is on a 2011 IMac with an 860M video card. Everything else seems to work fine including youtube videos.
Same issue here with a mini 2011 (HD3000 integrated GPU)
 
This was no clean install.

Hi @Ausdauersportler

I did a clean install again (with your patch-kexts.sh) and I don't understand something.

The following error is again indicated:

Code:
/patch-kexts.sh: line 747: zip: Command not found

The line concerned is:

Code:
zip -q -r -X AppleGraphicsControl.kext.zip AppleGraphicsControl.kext


I looked in the micropatcher USB key, the zip utility is not in /usr/bin/, there is /usr/bin/unzip but not /usr/bin/zip.

There is also the file AppleGraphicsControl.kext.zip file on the micropatcher USB stick.

Looks like this is a patcher bug or I misunderstand something ?

Please, until I fixed this run the patch-kext.sh from the running Big Sur! Open a terminal, enter

Code:
/Volumes/Install\ macOS\ Big\ Sur/patch-kexts.sh

Wrote this yesterday, unfortunately not explicitly enough!

P.S.:
But even with the missing zip in the recovery environment the unpatch would not delete any longer the AppleGraphicsControl.kext. It will remain simply including the plist patch. Next version I will revert the plist patch instead of backing the file up and restore it later.

I'm trying to install on a Late 2012 Mac Mini. I download the InstallAssistant.pkg, used createinstallmedia to create the installer, then used the latest micropatcher, reboot to EFI, turn back on, and boot from the installer. When I choose to install Mac OS Big Sur, it says the InstallAssistant is damaged.

I've tried this with 2 different USB drives, USB 2.0 and USB 3.0. I'm following the directions 100% but I can't seem to get a working installer.

Please download again, this is surely not a new problem and surely not a Big Sur related one.

I've successfully installed Big Sur 11.0.1 on my late 2012 Mac Mini; everything works as expected, meaning all is well except WiFi, but that's ok for me.
Overall, I'm underwhelmed; biggest annoyance so far is that Carbon Copy Cloner can't create clone backups anymore...
Hoping that future updates would arrive via System Preferences/Software Update – which is not the case so far, at least not with the dev. beta of 11.1.

Having received recently the same model I will upgrade with 16 Gb of memory, I would like to know if you are using the original internal DD or a SSD who replaced it and which method you used to install Big Sur. Thanks for the infos
I'm using an internal 1TB Samsung SSD (the original HDD is in the other bay) and worked with @barrykn's big-sur-micropatcher.

OK ! Thank for all the help 👍 . While waiting for the next version of the patch, I will read again the micropatcher documentation and your other importants posts again , to better understand the kernels extensions and other important files ;)

Have a good day :)

The next version of the mc or patch-kext.sh will not need any user interaction for iMac 11,x or 12,x users. Found a way to detect the graphics card used and the system so the patcher logic can choose all needed extensions automatically. Hope it will work out...

I know this works for Catalina because I have no problem running Catalina off a RAID 0. My only question to you is does this method work for Big Sur?!!! I’m gonna give it a shot but I doubt It’ll work for Big Sur because I’ve tried similar methods.

Mail 14 does not work with the latest SpamSieve beta on my unsupported Mac Mini late 2012; maybe due to missing the drivers:

Thanks to @Glemp, @pyedog, and everyone else on this forum of their assistance. My MacMini late 2012 runs like a charm on Big Sur and I must say that I don't understand why it is not supported officially. I have 16GB RAM, which makes a bigly difference, but I have yet to experience any glitches and everything works smoothly and is fast.
For me its almost flawless. Top bar takes a long time to load after login for me. Something like 20s. It is longer than boot itself. Maybe not a clean install related?

Another point is screensaver lag. Drift and even Flurry are stuttering like mad. Something like 5fps.

Do you have fast loading top bar and fast screensavers?

There seems to be a lot of variation on this. For me (mac mini 2012 2.3Ghz i7 16GB RAM 2 FHD displays) drift runs smoothly. For other folks with almost identical hardware it seems to stutter ... it's not clear where the difference lies ... some folks with 2018 macs claim drift stutters for them.
