macOS 11 Big Sur on Unsupported Macs Thread

[ImpetuousRacer]

I upgraded to 11.3 via the Micropatcher and after applying the wifi patch, I get the following message after logging into my Mac. How can I address this as I haven't seen this before after upgrading on my unsupported Mac.

View attachment 1765034

I'm having the same exact issue. Mac mini (Late 2012) 16GB, 2TB SSD.
Used micropatcher 0.5.1, same process as always, never had this issue on any other versions.
Any fix to this?

UPDATE 1:
So, I found a fix to this. Others (unrelated to micropatcher, but receiving this on various OSX versions) said to start computer once in safe mode. They would not receive the error once booted into safe mode, then restarted the computer normally and the error message no longer occurred.

Funny enough, I shut down the computer, tried to start in safe mode by holding the shift button down (but never got to safe mode, just received a no symbol (circle with slash through it) with text of support.apple.com/mac/startup underneath it). Turned computer off, turned back on, and I no longer receive the error message. Tried multiple restarts and shutdowns and still good. I checked console from the start and never showed any kernel panics. Hopefully this helps others with same issue.

Test Result
BigSur 11.2.3 work boot without Force iMac metal patch
latest OCLP
BUT graphic and mouse problems are not fix at all

About

YouTube test

Vedic test

It’s first time to boot with no Nvedia patch I think update patch solve it
but any latest of BigSur need patch Nvidia,
but after that we need to fix graphics problems

Again, using the phrase NVIDIA metal patch at this point in the patcher is a misconception and using it with your system is another. It is meant for a system having a new metal NVIDIA card which your iMac DOES NOT HAVE! Using a native Metal GPU (either AMD or NVIDIA) does not need any patches, just some settings to make it fully working which is done by selecting this point).

--

The graphics acceleration patches needed for your system will be applied after installation of Big Sur by using the OCLP patcher app, again.

Start the OCLP app again, choose

3. Post-Install Volume Patch

then

1. Patch System Volume

Let the patcher app patch your system and reboot the system after the patcher did it's job. After reboot graphics acceleration should work to some extend (this is still beta software and we do not know if it will be ever fixable as for Catalina. BTW it is the very same guy @ASentientBot creating this patches as for Catalina before).

11.3 full installer update (not OTA) has been a mission for me - and so far unresolved. My cMP 5.1 has NVMe, SATA 3 and USB 3 PCIe cards added, with 11.2.3 and all previous beta and full installers working just fine. I’ve been running 11.2.3 from an OWC Aura 1TB stick on an unbranded host card, bought off eBay with Mac specific firmware supporting 10.6.8 onwards.

I’d avoided trying out any 11.3 betas and glossed over, at my peril it appears, reports that NVMe expansion was breaking 11.3 builds. I have since found another Macrumors forum (https://forums.macrumors.com/threads/mac-os-11-3-has-broken-support-for-older-mac-pros.2289056/) dedicated to this overall problem (eg. PCI switching not working with 11.3 because Apple has replaced an IOxxxPCI.kext, relating to many types of cards, since 11.2.3). Note that cMP3,1’s seem immune to this kext update, as they apparently don’t do PCIe switching either at all or the same as a 5,1. Therefore, running 11.3 off an NVMe add-on card and stick should be fine (with the firmware updated for NVMe support).

Before I knew about the kext change, I tried installing 11.3 on my NVMe drive with the 0.51 micropatcher method but ran into no end of boot loops and verbose message failures to load the files. I tried installing with OCLP without any more success. After finding the info about my NVMe card (and USB3 card) likely causing the fails, I removed all 3 add-on PCIe cards and tried to install 11.3 on a temporary 120GB Sata2 HD. So far, I’ve still been unable to get to the final User selection screens.

It is likely that the only method that may work for me, to still use my PCIe cards, is to install an unpatched 11.3 booting with OCLP, spoofing a MP7,1. This will leave a sealed system, which I’ve been avoiding up until now. Have others - reporting or having success with 11.3 on their 5,1’s - managed this to an NVMe drive ‘and’ kept an unsealed system using a micropatcher (ie. Hax3) method to install it?

I just tried installing Big Sur 11.3 on a Mac Pro 4,1/5,1 and after booting the EFI selection followed by the MacOS Installer, the progress bar moved for about a minute and then I got a Circle/Slash (Prohibitory Symbol).

Machine is a 2009 with 5,1 firmware, W3690 CPU, 56GB RAM, 2TB HDD, GTX 680, two 4K Dell S2817Q monitors, BCM94360CD Wifi/BT cards, USB 3.0 card, NVME PCI-E card with no blade device in it now

I've previously installed on this machine using the micropatched method.

From what we have heard here the micropatcher still works for other machines with 11.3, so assuming you followed the guides it should work. Nevertheless (just read the post before your own) I doubt you can have success for a completely different reason on your particular system. Please search back a few pages to get an overview what happened.

You missed the famous @ASentientBot added back graphics acceleration support for a list of pre metal systems and there is a public beta phase using OCLP. Just changed the first post to reflect this recent changes...

Of course this does not bring metal support to non metal GPU systems. So some apps may not work or only within some limits as before.

Hello my friend. Just have a question. My MacBook Air mid 2011 has Intel HD 3000 legacy graphics card. Will the patch improve the acceleration for this card. . Is it possible to just get the patch support for the acceleration. Tks
Read the OCPL docs file and i Know the success is partially which got me doubts.So just asking

 

[houser]

Just a preliminary report of at least some success with OLP on a Macbook Air 3,2 late 2010.
Big Sur 11.3, OLP 0.1.1
Using the standard docs it definitely works as-is so very happy with that so far.
One issue that I still see is the reported issue here of having to use option during boot both during the install, for every reboot and now after every manual reboot.
But once up and running it is so far pretty great for general use on an old machine off the bat.
Will keep testing

Many thanks for this!

The magical link your are looking for post this one. I would give it a go using the 11.2.3 - not the 11.3 unless we have more data points.
Changed the OCLP docs to include it and made a pull request. Hope it will be updated, soon. The development is really hot right now and we cannot keep up with changes and communication at the same time.

Tks. Now that I am on 11.3 will wait till something comes up. 👍

Proposed already a change to the docs!

The magic is using the CRTL key when selecting the OCLP EFI for the very first time. This way it becomes the standard boot object and you do not need to wait for reboots. This is standard Apple system administration

 

[houser]

Many thanks @Ausdauersportler
I will say that this beta is really very promising and I am pretty happy as is
as it is way beyond my expectations at this point. I can use it as-is.
But if you want feedback on what issues I see, here is a very short list.
Other than that it works pretty great on MacBook Air 3,2 and H264, h265 video in vlc and Kodi is very functional.

reboot still requires option to select efi
some issues with sleep induced by timer still requires procedure to wake

some graphics issues that may seem related:
Apple home app does not show inactive scenes or accessories but works other than that
(It was exactly the same on the dosdude Catalina patcher on MacBook Air 3,2 and if you disable the legacy graphics
the app works as it should if that helps?)
dim of screen does not work but you know that
When dimming with the brightness slider app, some things like mouse pointer and clock in screensaver does not dim

Other than this i friggin love it..

i Did already post install volume and audip running from patch OCLP 0.021
so always I uses this steps
i sent Vedic and YouTube with sound but cutting by frame buffer lagging
I will try!

1. Use control on boot when selecting the OCLP EFI - so it becomes the standard boot object (which is basic Apple sys admin knowledge)
2. Apple Home relies on metal and surprisingly it will not run perfectly on non metal GPUs, same applies to Maps, Photos and some other new apps
3. Graphics acceleration means patching back OpenGL, not emulating metal!
4. Feedback on the Discord server @khronokernel announced lately, this is not the developer platform, this is a user forum.
5. Possibly we all know the most graphical glitches and problems from the internal alpha phase. This is no new information. Application problems will be a target later on - I guess. Currently it is about basic functionality.

About Big Sur 11.3 updates and new installations:

OTA:

1. iMac12,2 AMD 4130 OTA 11.2.3->11.3
2. iMac11,1 AMD 4150 OTA 11.2->11.3
3. iMac11,3 AMD RX480 OTA 11.2.3->11.3 (that one was so quick, when I came back the login screen already was up, again)
4. iMac12,2 AMD WX4170 Beta 11.3 (20E5229a) -> 11.3 (had to change kack from the developer seed)

New installations:

1. iMac11,2 legacy graphics AMD 4670M works wonderfully with 11.2.3 and @ASentientBot graphics patches
2. iMac12,2 NVIDIA K3000M @dosdude Catalina 10.15.7 -> OCLP Big Sur 11.3

This last cross macOS update stuck at 12 minutes to go for an hour or so during the first installation phase. Rebooted manually and from there it went through with three reboots automatically. I know, currently not a supported way to make an update, but it worked, all data and settings preserved.

No app needed, no new process, no other GUI. It is all just using Apple software update and Apple documented procedures including the download and generation of an USB installer.

how can i notice that

automatic GPU switching on my mac is working or not?​

thx

 

[johnrak]

I used OCLP 0.1.1 and a USB stick with Mac OS 11.3 to update from patched 11.2.3 and the update was successful!

I didn't patch my system this time. It seems to work fine. It's been only a few hours and I haven't found any bug. Tell me if you want to me to check anything in particular.

I noticed that the default settings in OCLP for Metal patch and upgraded wifi were "None" and "False" although I have upgraded both. I didn't change anything in the settings. Should I change them? I have installed it in the internal drive and it boots fine.

 

[jacob_pro]

i run software update “BigSur 11.3 take 2 hours” and restart fail
and again with boot issue like this may be I wait again more hours


i Shutdown it and restart it again progress not run completely and succeed with BigSur 11.3

There came now a few some messages in of broken installations. When such a thing happens it is time to enable verbose boot with OpenCore instead of sitting blindly for hours in front of a system.

And please stop posting those pictures showing nothing! We believe you telling us the boot sticks for hours, now.

And as I wrote before it is known that 11.3 with legacy video has and had it's problems. This comes close to masochism, now. But what do I know about humans...

How well would my late 2012 iMac (3.2 GHz Quad i5 with GTX 675MX) work with unofficially installing Big Sur?

 

[antifocus]

I am surprised this is a problem... The late 2012 retina display MBP is almost completely supported by Big Sur, even without OpenCore (if you physically upgrade the Wi-Fi/Bluetooth card then in terms of hardware it is completely supported; but you need OpenCore or a patcher to force it to install, because Apple still detects it as an unsupported model).

I use Big Sur and OC on the same model all the time with no problems at all. I've gone through every single beta version of Big Sur (at least, since late last year) and am currently on 11.4 beta 1. So I'm thinking that with more info, this should definitely be fixable..

When you say "can't boot from internal drive" what do you mean? That it doesn't even show up as a boot option? Or that it does, but then when you select it, it crashes, hangs or otherwise doesn't work in some way?

Hi, thanks for your input.

If I don't have my OC USB installer plugged in after reboot, it'll just show a black screen and a warning sign with mac startup URL if I hold the power button.

FWIW I was on the original 11.2, not 11.2.3.

I think I'll try to install 11.3 with micropatcher on top of it now then 11.3 with OCLP now. At worst I'll start from scratch then recover from TM backup.

 

[mwidjaya]

If it works fine with OCLP EFI on USB stick, it probably means you did not complete the EFI install on internal disk properly.

Did you follow all the steps? Including reboot with option and selecting EFI on internal disk?

hi guys
i have macbook pro retina 15" mid 2012

i could install big sur version 11.3 (20E232) on my mac 1 days ago.
its wonderfull
every thing is working , even wifi . i could fix that

but there is big trouble

today i notice that location services is not working !!!
(its enable in the setting/security&privacy/location service)
i tested it many times,i disabled and enabled, i restart many times,but
still not working,and not shows its icon on menu bar ...

anybody have the same trouble ?
plz help, thx alot guys , thx again

another question
how can i notice that

automatic GPU switching on my mac is working or not?​

thx

Let's see if I can help since I have the same device and have no troubles.
First, please use colored text less; also less bold typeface. It annoys most of us! Thanks.

You didn't say what your installation method was. I use BarryKN's micropatcher v. 0.5.1, so I know how to do that install, but don't know much about OCLP installs (others here do so be patient and they will answer).

If you still have your patched USB installer, just shutdown, reboot with option key depressed to get Apple startup selector. Choose the USB stick and reinstall 11.3 right over your existing install. Your data, apps, and settings will not be harmed. This is a fast and effective way to correct problems.

Read Apple's "How to Use Network Locations on your Mac."

If you have installed gfxCardStatus v.2.5, you can use it to see which GPU is operating and set Dynamic Switching. You will need to run a Terminal command to disable displaypolicyd which prevents dynamic switching on our machines. The command is sudo launchctl stop com.apple.displaypolicyd. Enter your password on Terminal prompt. You will need to do this after every system startup.

Lastly, I'm sure the moderator will ask you to create a signature and put your device info, current system version and build, and your patcher/install method used. Add any information you think would be useful to help diagnose your problems. Thanks and welcome to this forum!

Yes I did, including manually moving the OC files to the internal drive.

 

[mwidjaya]

That is my best guess of problem you face.

Also, there is no need to manually copy files. You can use OCLP app itself to install the EFI to internal disk; less chance of manual mistake.
