iM 4,1-14,4 2011 iMac Graphics Card Upgrade

[astuermer]

DId you update the kexts as per the first page? Also, just put the log into code box in the post. Nobody, is going to download that file because it keeps asking to install flash or some other nonsense.

Big Sur on iMacs Late 2009 and Mid 2010 and Mid 2011​

Q4: Do I have to make a clean install?
A: Depends on your backup/restore! Today I upgraded on a second system my existing Catalina installation to Big Sur and patched it. Right now I do not miss a thing, but you will know after a while if everything is working as expected. Please keep a backup to be able to go back if your most favourite application does not work on this new MacOS.

How you upgraded from catalina to big sur? I want to try this way.
I've an iMac 2011 27" with K1100M.

 

[Ausdauersportler]

How you upgraded from catalina to big sur? I want to try this way.
I've an iMac 2011 27" with K1100M.

Follow the guide I made, download the installer and the micro matcher, follow the guide on this micro patcher page step by step. When patching call the script patch-kext.sh with the option --useOC. Otherwise you get Whatevergreen and Lilu installed on disk and would have to disable in on your OpenCore config.

It is straight forward, I did this direct upgrade from Catalina to Big Sur yesterday and had no trouble, so far.

EDIT: outdated

 

[Ausdauersportler]

That why I am asking the knowledgeable expert 🤗
In the post it appears that RX480 is flashed and recognised as RX580.
That is the same as WX7100 which is also listed as RX580 in the About box, but WX7100 has 8GB VRAM.
The RX480 has only 4GB VRAM. I am not so sure whether it would work with the WX7100 config, or the generic AMD config would suffice.
There is also a RX580 4GB MXM version. But don't dare to try with the RX480 ROM as it is too expensive to experiment. Up till now luck isn't on my side

You still miss the main part:

When using an iMac 2009/2010 you need the special config file config.AMD.BS.plist and rename it to config.plist. Otherwise no Big Sur installer will even boot on your 2009/2010 iMac. This may be complex, but still I ask you guys to write down the parts yuo need to do this upgrade. I will not come in as a last second expert to do the trouble shooting just because you are not willing to organise your work properly. For this reason I write so many documentation alike posts.

Notes:
I will get rid of the different AMD plists. Wrote this before, there is no gain to use and maintain different ones. I do not started with this.

With an 2011 you would need the WX7100 version. And you gave the answer yourself because you were starting to think about it. The OpenCore config does not rely on the amount of memory installed on a video card.

On the long shot we will see possible only two config files each for NVIDIA and AMD to avoid confusion. But I am a one men show. I cannot change and test everything in a single 24h day.

About the ROM: Please use one of the recently published two versions (4GB WX7100) made especially for the RX480. It is the 4GB WX7100 and basically this card is a marketing object. It has the same chip as the WX7100. Some years ago others found out that you can flash a RX480 into a RX580 because these cards are so similar.

Fully understand. It is a daunting task that demands skill and time and investment, while we ripe the benefit.
I know that iMac 2009-2010 needs OpenCore for BigSur.
My aim at the moment is only Catalina for my iMac 2010 which is my main working one.
Just wonder whether the BigSur config can also work for Catalina or not ...

 

[Ausdauersportler]

What do you mean by that?

You can install Big Sur over your existing Catalina installation ( id did this yesterday, but there will be some apps needing an update), you can create a second APFS container or partition on your disk and install Big Sur side by side using the same OpenCore config file.

BUT you need OpenCore anyway with all AMD cards to get the fill video acceleration (HEVC).

Sorry for the confusion, and I may not have made myself clear.
The query is whether that BigSur config can be used to install Catalina over High Sierra, or is it just solely for BigSur as its name implied, while those other configs without BigSur are for Catalina Install.
My bad

This is a Big Sur installer, only.

For the 2010 please simply use the @dosdude1 Catalina Patcher and the latest Catalina Loader with the WX7100 plist.

Question back: Have you ever thought to used the @dosdude1 Mojave patcher to install Catalina???

 

[Massimo Ghielmi]

After USB stick patched, how I install it?

 

[Ausdauersportler]

After USB stick patched, how I install it?

This does not work this way. Please read the docs and get yourself ready. I cannot simply guide everybody through this step by step.

I've read your post in previous page and micropatcher guide but I've don't read how install over Catalina without lose data. I don't remember if is possible with simply boot on USB as for a blank installation. I've already patched my USB key as your and micropatcher guide.

Maybe I've lost a message/guide?

Thanks @Ausdauersportler

I've read your post in previous page and micropatcher guide but I've don't read how install over Catalina without lose data. I don't remember if is possible with simply boot on USB as for a blank installation. I've already patched my USB key as your and micropatcher guide.

Maybe I've lost a message/guide?

Thanks @Ausdauersportler

Q4: Do I have to make a clean install?
A: Depends on your backup/restore! Today I upgraded on a second system my existing Catalina installation to Big Sur and patched it. All user data remained untouched! Right now I do not miss a thing, but you will know after a while if everything is working as expected. Please keep a backup to be able to go back if your most favourite application does not work on this new MacOS.

@xanderon👍
The memory latency in your base rom for that Clevo/Dell card is different than what the original Dell rom was built upon.
I will be updating my K3100M post soon with the new information for everyone else.

Hi Nikey22,

If you need beta-testing, I'm willing to do that. I'm using the K3100M Clevo/Dell in a iMac 2010 27''.

Thanks, now I've understand better the steps but when I'm try to install, installer can't install in my SSD APFS Catalina volume (grey volume "you need to update your system for install in this disk")

Sierra and High Sierra Package Installer

( iMac 2009-2011 AGC, FakeSCM, Lilu, WhateverGreen, AppleBacklightFixup installer)

(not compatible with OCLP or Catalina Loader/OpenCore, replaced in functionality by OCLP)
​

Attached you will find the a kernel extension package installer currently working on Sierra 10.12 and later. SIP needs to be disabled. Boot into recovery, start Terminal app, enter csrutil disable and reboot directly into your macOS and install the package.

It will patch the current installed AppleGraphicsControl (AGC) as described in this post addressing the black screen issue and install the AppleBacklightFixup needed for ++ type Nvidia cards side by side with the @vit9696 Lilu and Whatevergreen. As an option you can have the FakeSMC extensions get installed.

The NVIDIA ++ cards are this running with a BIOS from @nikey22 and marked in the table on post #1 as type ++.

After starting the Apple package installer (double click) you can choose the destination and select the packages to be installed according to your wishes. For this reason I separated the complete sets in several subsets. You can use the installer to patch AGC (this will be done in any case), and install addionally BacklightFixup, FakeSMC, and WhateverGreen/Lilu. You have to select at least one kernel extension to be installed. Only the FakeSMC is really optional.

FakesSMC will be needed b the HW Monitor app to provide full details on all sensors available on your system.

What will this package installer do:

1. Patching AppleGraphicsControl AGC (all iMacs, Nvidia card users, only)
2. Nvidia BacklightFixup (all iMacs, only NVIDIA ++ GPU)
3. FakeSMC Package (all iMacs, all graphics cards)
4. vit9696 WhateverGreen and Lilu (not compatible with OCLP and Catalina Loader)

Supported hardware:

iMac 11,x (Late 2009 and Mid 2010) with NVIDIA Kepler GPU
iMac 12,x (Mid 2011) with NVIDIA Kepler GPU


Supported MacOS:
macOS Sierra 10.12.1, High Sierra, only!

on iMac11,x please use OCLP
on iMac12,2 please user other packages with Mojave/Catalina


Recipe:

Disable SIP, download package, double click, enter password if asked for, select disk and the extensions to be installed, finish installation and reboot.

You may select only a single of the packages below! The AGC patch will be applied in any case.

Attached you will find some selections screen shots. You can use the installer to select a single package only.

Have fun and please report back!

Notes:
12/07/2020: Late Nikolaus gift, new package installer and deinstall package

10/20/2022: You may use the AppleGraphicsControl AGC patch only using AMD GCN4 cards, too. Deselect all three other options (Nvidia, FakeSMC, Lilu/WhateverGreen) to avoid the black screen issue on High Sierra!

This is great, thx for the update !
I was looking for Mojave support for our 2011 27" GTX765M iMac's..

 

[Murometc]

From this post I learned that not all GTX 8XX series graphics cards are usable in my IMAC mid. 2011.
Some non-functional ROMs are discarded.
I am planning to purchase a GTX 780M.
They have the following ROM:
80.04.BD.00.05
foto 1
foto 2
or
80.04.92.00.01
foto 1
foto 2
This is an unverified BIOS file. In addition, these two boards look different.
Does it make sense to purchase?
Will they be functional after flashing the BIOS?
THANKS.

Mojave Package Installer

(Mojave iMac 2011 sleep/AGC/iGPU/AppleBacklightFixup installer)
​

Attached you will find the a kernel extension package installer currently working on Mojave 10.14.1 and later. It will install all the packages listed in this post @highvoltage12v made years ago.

It will patch the current installed AppleGraphicsControl (AGC) as described in this post addressing the black screen issue and install optionally the AppleBacklightFixup needed for ++ type Nvidia cards.

After starting the Apple package installer (double click) you can choose the destination and select the packages to be installed according to your system and card type. For this reason I separated the complete sets in several subsets. You can use the installer to install AGC, BacklightFixup, FakeSMC, and WhateverGreen/Lilu on 2009 and 2010 systems, too.

1. 2011 HD3000 sleep extensions (Mojave)
2. Nvidia AppleGraphicsControl AGC (all iMacs, Nvidia card users, only)
3. Nvidia AppleBacklightFixup (all iMacs, Nvidia card users, only)
4. optional AMD HD3000 sleep (AppleIntelSNBGraphicsFB.kext, 2011 iMac AMD Polaris card users only)
5. optional Nvidia AppleGVA.framework (Nvidia GPU 2011 only)
6. FakeSMC Package (optional to all iMacs, all graphics cards)
7. @vit9696 WhateverGreen and Lilu (optional to all iMacs, all graphics cards)

1. iMac 2011, Mojave, new AMD GPU (with Open Core)

2. iMac 2011, Mojave, new NVIDIA K610M, K1100M, K2100M (765/770/780) GPU (with Open Core)

3. iMac 2011, Mojave, new NVIDIA GPU (except GPUs listed in 2. needing Open Core for brightness control)

Notes:

- This installer currently shall only install files on Mojave 10.14.1 and later!

- Do not use it with any OCLP installation. Do not use it with Catalina, Big Sur or Monterey!

Recipe:
If you are not willing to experiment on your current Mojave installation please create a new APFS Container, install Mojave 10.14.x into it (it will use barely 15GB on your disk), boot into this newly created MacOS, and use the installer package to do the final adjustments. Check and report back!

You may use this with AMD cards, too. But please to not install FakeSMC, Lilu, WhateverGreen, AppleGVA.framework and the Nvidia AppleBacklightFixup in this case!!

Have fun!

Edit:
11/14/2020: Test on iMac 2011 with WX4170 successful!
11/26/2020: Update to address 2011 iGPU support issue - please check!
12/15/2020: Late, late Nikolaus gift, new package installer and de-install package

I apologize in advance for the question) tell me if it is possible to install my gtx880m video card with the installed BIOS for iMac 2011 in another iMac 2013 will this firmware work?

thank you!

 

[Ausdauersportler]

Thanks, now I've understand better the steps but when I'm try to install, installer can't install in my SSD APFS Catalina volume (grey volume "you need to update your system for install in this disk")

you need to update your system for install in this disk

i.e. possibly the Big Sur installer will only update starting from 10.15.7?? My upgrade started from 10.15.7....

thank you!

nope 2013 iMac's dont have an MXM video card slot.
the 2011 iMac's where the last Apple iMac's which had an "upgradable" MXM video card slot.

Al newer imacs the video card GPU is onboard on the logic board, and cannot be upgraded

slightly off topic

Please check ifixit.com for your options to enhance an iMac 2013 - you will be surprised! And then your will suddenly recognise why we all here work only with Late 2009 to Mid 2011 iMacs.

** NVIDIA Quadro K3000M Mac Edition ROM **
Genuine Native Boot Screen & Brightness Control



​

Preamble:
These cards are designed with a PCI legacy 2.3 architecture (2002). This is reflected in their roms which has led to some trouble developing a compatible rom for the iMac. My rom has a modest clock table boost as well. These workstation Quadro cards really boost well.

Pre-installation Requirements:
- iMac (27-inch, Mid 2011) , model: A1312 (EMC 2429) Mac-942B59F58194171B (Test machine)
- BootROM: 87.0.0.0.0. Please use High Sierra to update your BootROM to latest version.
- Nvidia Quadro K3000M, GPU Variant: N14E-Q1-A2 Dell or HP
- Heatsink 3-pipe with appropriate clearance mods for the inductors
- Hynix -BFR Vram; -AFR will require a different Memory Table. Please let me know if you have a -AFR based Hynix card

Post-installation Requirements:
Brightness Control Stepping Mod:
-Turn computer on, hold down Command(⌘)-R
-Choose Utilities > Terminal
-Enter:csrutil disable
-Reboot
-Download and open 'Kext Utility v2.6.6'
-Navigate to S/L/E (System/Library/Extensions)
-Copy "AppleBacklight.kext" to Desktop
-Edit: AppleBacklight.kext/Contents/Info.plist
-Scroll down to: IOKitPersonalities > AppleIntelPanelA > ApplePanels
-There you find several Apple LCD profiles.
-For the iMac 2011 27" machine locate:

<key>F10Ta007</key>
<data>
ABEABgALABQAHAAnADMAPwBOAFwAZwBzAIEAkQClAL8A2wD/
</data>

-Change the <data> section to:
ABEAAgA3AF8AigCzAOsBJAFnAakB1AIJAlQCogL4A00DlgRpBGk=
-Drag your modded kext into Kext Utility, allow it correct permissions
-Applebacklight.kext.bak folder will be created
-Reboot

The above data pattern will allow for a wider span of steppings for the brightness control and utilizes more of the capacity of the HD3000. If you have a different machine, your panel ID can be found by going to System Preferences > Displays > Color > Open Profile > mmod

Caveats post-install/Bugs:
-16bit resolution glitch of UGA_DRAW_PROTOCOL - temporary solution: activate a sleep cycle
- WSON based bios chip. Clip rescue is not possible

Updates:
12-8-2020: detuned card to more reasonable clock speeds for better stability


Insanely Great!

Hi .. May somebody tell me, whether the "Hardware Video Accelaration"(NVENCODE) for Kepler Cards in Big Sur is still possible ? Actually I've an iMac 2010 with K2100m booting over OC 0.6.3. In Catalina I could start Parsec and PS4-Remote Play with Hardware-Decoder, but in Big Sur there is no Hardware-Decoder anymore, because of that PS4-Remote crashes ..

Thanks ..
