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

[herrdude]

I uninstall lilu and whatevergreen to replace original settings.
I try to use the fake backlight, so, everything on opencloverconfigurator (kernel) selected from lily, to the fake backlight.
It doesn't work, boot to a withe screen with apple logo, no progress bar.
This is not a big deal... everything else works quite nice. I don't want to give you guys to much trouble, and I'm just a "humble last place newbie" compared to some of you, that are the real gurus... ;-)

Does it boot normally without the OpenCore bootloader?

Does it boot normally without the OpenCore bootloader?

Yes, everything normal.

 

[herrdude]

Yes, everything normal.

Show a screenshot of the OpenCore Configurator on the Misc and the Kernel window.

And Kernel page ;-) Also, I forgot the Security tab on the Misc page.

On the security page, change Vault to optional and make sure AllowSetDefault is checked. Otherwise, everything else looks good.

@Jforte can I see the devices tab? This is booting with the 780m.

This is booting with 780m, yes... Excuse me, where is "devices tab" ?

Didn't work neither... :-(

You're missing the entry for fake Brightness levels. Since the beta 3 ROM doesn't currently have those values in the VBIOS. The iMac will always kernel panic on AppleGraphicsPowerManagemement.kext. To temporarily remedy this issue, I have created a config.plist to have these faked "pwm-info" values entered. I'll attach the config.plist for you.

 

[Jforte]

With lilu and whatevergreen selected, it didn't boot, without it, it bootted well. No differences on Netflix, or HBO on Friendly streaming or safari, don't work.
Thank you (and herrdude), for the trouble...

EDIT: 3/30/20 AppleIntelSNBGraphics.kext has been updated to include board ID for iMac Pro/AMD-WX Series Config.plist. You can now have working sleep when your board ID is changed to 7BA5B2D9E42DDD94 to enable HEVC.

I am creating a guide linked to the first page to show how to reinstall HD3000 sleep kext as well as bring back Airplay and intel Quicksync rendering. This guide is exclusive to 2011 iMacs Running Mojave or Catalina.

1. download Kext Utility from here http://cvad-mac.narod.ru/index/0-4 download Hackintool from here http://headsoft.com.au/download/mac/Hackintool.zip download and unzip my files at the bottom of this post for Mojave or Catalina.
2. Move files to the desktop, (Catalina only) Open Hackintool, move to the Tools tab and click on the GateKeeper icon, enter your password and Finder should restart, this unlocks the System Partition.View attachment 885972
3. Unzip the Mojave or Catalina files and unzip them to the Desktop. Drag Kext Utility into the same folder as the kexts. Drag the kexts onto Kext Utility, they will install but Kext utility will give a timeout error in Catalina, this is normal. You can reboot your iMac now, Sleep/Airplay should work. View attachment 885982View attachment 885983Part 2: Enabling Intel QuickSync for rendering using the IGPU.​
4. Since Mac OS Mojave, Apple changed the "AppleGVA.framework to longer be compatible with Sandybridge CPU's. To reenable QuickSync we have to reinstall a Private framework from High Sierra. The 'AppleGVA.framework' included works with both Mojave and Catalina.
5. (Catalina) Use Hackintool to unlock the System partition as shown earlier
6. navigate to /System/Library/PrivateFrameworks/ take the unzipped AppleGVA.framework and drag it into a blank area of the PrivateFrameworks folder. click "Replace" from the Finder popup. View attachment 885986
7. Open terminal and enter the following:

   sudo chmod -R 755 /System/Library/PrivateFrameworks/AppleGVA.framework THEN ENTER
   sudo chown -R 0:0 /System/Library/PrivateFrameworks/AppleGVA.framework

View attachment 886317
You can reboot now.

Optional you can download Mac X video recorder and check to make sure intel QuickSync is enabled.

Spoiler: Original post

Okay,
I have figured out the slow boot issue in Catalina and allowing the HD3000 kexts to be installed along the "AppleIntelSNBGraphicsFB" that was mentioned earlier. Turns out you need to modify the IOSURFACE.kext file (File from @dosdude1 patcher, all I did was replace it within the kext) and install the patched iosurface.kext with the HD3000 kexts. Now I have a normal boot time and proper sleep/wake function.

I also added the AppleGraphicsPowerManagement.kext from the patcher, I have not done any testing yet if this kext has any improvement on MXM cards, but it's a newer version than the one from High Sierra 110.23.46 vs. 110.23.37

EDIT: looks like the AppleMCCSControl.kext should be added along with IOSurface.kext to prevent artifacts in Safari.

To install I use "Hackintool" to unlock the Catalina System partition to install, then drag all the files on top of Kext Utility to install. Alternatively you can open terminal and type


I also added Mojave proper sleep kexts to this post as well.

Catalina Sleep Kexts still work as of 10.15.2, if performing a software update it is necessary to reinstall AppleMCCSControl.kext. Otherwise webpages on Safari won't load right.

is there an easy way to revert these changes?

thanks for any wisdom

Are you currently booted with open core? If so you could have a copy of AppleSNBFramebuffer in S*/L*/E and enabled in Open core. You can only have one copy installed. If else you could be missing files in the Open Core directory.

thanks for the reply

no I am not using open core

 

[nathansz]

I don't see appleSNBFramebuffer in S*/L*/E. is it meant to be there?

the only other issue I've noticed is that my camera is sometimes very laggy, sometimes seems to function perfectly. I don't really use it but mentioning in case it's diagnostically helpful

thanks again

Guys I currently I have a 2011 21 inch iMac, will a AMD WX7100 will work in it or not?

I cannot say for an AMD Card, but Nvidia cards that are MXM-B do have power draw issues. I would proceed with caution, and have a backup 27" iMac for it. But it would be interesting to know. It would probably be similar to sticking an AMD 6970M in a 21.5" iMac, which I haven't done.

I have saw YouTuber Luke Miani having used a GTX 770M in a 21 inch iMac which I think is a 100W card but even if a card causes some power issues, can we put a power limit on the card?

 

[Jforte]

770m is 75W. To put a "power-limit", why don't you use a K2100, for instance?

Simply performance, did any one had tried WX7100 yet?

It is a work in progress, i gess, for now...
If you limitit power, you limit performance...
You don't want a "ferrari", if your machine can only afford a Fiat, right?

 

[herrdude]

It seems like a lot of money to spend and it might be throttled by the power limit.

I had a 770m in my 21.5" iMac, it's was well documented here. The thing would kernel panic at the most random times. But there was always a pattern to it. It's all PCIe power draw related. It would kernel panic on high Airport/wireless activity. Setting up new Mac OS account. Opening iTunes with large libraries etc. It's basically there is no Graphics Power management Kexts loading in 10.14/10.15. Otherwise 10.13 is mostly stable. If you been reading my posts with this iMac it now has a 765m in it, I'm 90% sure I have fixed this issue by using the iMac Pro board ID, which makes a profile for Graphics Power management Kext load along with OC "PowerTimeoutKernelPanic" have greatly helped.

So you want to say WX7100 will work fine in my 21 inch iMac.

Could someone please share link to GPU that 100% will work with my device? I want to buy any GPU under $150, just don't know where to buy. New GPU will be best (afraid to buy used one, because they can be already dead ones).

iMac 27" (mid 2011)

I had a extra 860m $100 and selling on marketplace in WPB area Florida if you are in the neighborhood...
