Did someone tried the K3000M ( GK104 ) yet? Those who know to work are extremely expensive these days (like the K1100M for 100€+, i bought one a year ago for 35€). Now i could get 2 K3000M for a Dell PRECISION M6700 / M6800 (X5FFM) for cheap.
Got a tip for us?

I’ve found the same prices as you. The recommended cards have jumped in price but I’ve seen brand new K3000m cards for decent money.
The funny thing is that obviously the silent majority of users do not share your problems and experiences. My conclusion would be that your setup is broken, not the stock OpenCore config on the Catalina Loader.
And you tell me that your 70 year+ old relative is going to use TDM? (Have never used TDM because I do not own the fitting cable, so there might be a problem..).
You can hide the "self" tag from the OpenCore boot screen and avoid this particular error prompt and you can configure this OC to straight boot into a predefined MacOS installation following the guide @herrdude published (basically pressing CRTL + ENTER in the same way as on native Apple systems). Give it a chance!

This thread is now 7 years old. The chance to have every poster reading your questions is near zero. But there is a search button on the top left of the screen and you can limit the search results to this thread, only. Using this you can check each Kepler card you know. I would guess there is a non zero chance to find a (half) working vBIOS somewhere but you will face all the problems listed on page one and post one. Buy a card, install it, check it out and post the results.

Of course, I'm not blaming OpenCore, I clearly must have done something wrong, I'm just not sure what it might be. I have tried setting up OpenCore from a USB several times using both herrdude's guide and the guide you posted, but still am unable to solve them. The only thing I can think of is something went wrong with the flashing and I need to re-flash.
Fair comment.
Bought one off the bay... Just need to wait for it to get all the way to Adelaide, from the US
Total cost approx. $68 US, delivered. Cheaper than anything else I could find.
Adelaide? And i thought you were from NL I found 2 cards for 39€ each near Rotterdam.
hmmm should i buy both...

I have imac 2009 with intel i7 860. so I understood from the instructions, first install all kext files and finally replace the file AppleGraphicsControl
When searching the post @highvoltage12v made I read there "This guide is exclusive to 2011 iMacs Running Mojave or Catalina."
Do you have a 2011 iMac running Mojave or Catalina? Even the OpenCore guide I recently published is focussing mainly on the 2011 systems.
2009/2010 systems need only the AppleGraphicsControl extension.

Okay, I have a single USB flash stick with OpenCore, but mainly I use the SD cards - but there should be no difference. The only personal experience I have with USB flash sticks is: Using them with the @dosdude1 patcher for installation does not work endlessly. After a short while I have to rewrite them completely using the patcher to avoid installation errors. I did not spend any time into trouble shooting since reinstallation usually fix this.
It should work with both, but I use only the SD cards. And this is really stable since I use the very same two cards to boot a bunch of AMD or Nvidia systems.

I am still using High Sierra as I have to stay on this for TDM, so have not used the dosdude1 patcher (which I understand is about enabling Mojave/Catalina installation). Perhaps it's an issue with the USB stick then - I will try with an SD card. Do you think there is any point in trying to re-flash? Because other those two fairly minor issues, the card works fine and is recognised as a K2100M by nickDB by Mac OS, so surely this means the flashing was successful?
Hi!
In your position I would try a small 1-4GB SD card or another USB flash drive. The K2100M flash image should be fine, all flash utilities do to my knowledge a check, i.e. write, read, compare. From all the cards I checked and tested these small Quadro cards are the most reliable ones. You can even use them without a complex fan management, because the heat production even during a Valley benchmark is small (30W with the K2100M, less with K1100M and K610M). This may not apply in areas with hot and humid summers, but I live in central Europe and even climate change is not that fast.
Always: If you face problems first redo the software setup, then change hardware parts to fence out human or hardware errors.
Hope you get it running, soon!

I lived in Amsterdam for almost 5 years, which is where the moniker came from, then back to the UK for 3 or so and Adelaide since 2007. Visited Rotterdam many times, normally in a Citroen Berlingo full of broken IBM thinkpads.
39 euros is a very good price. $30 of the $68 I paid was delivery and import tax!
you are right this guide is for 2011 only. my mistake. should hardware encode in macx work in imac 2009?
According to this site I would say no - the former CPU did not have the hardware encoding/decoding on chip.
Phonetappa - I ran into the same errors as you, I was able to tell the flashing tool to basically ignore all the errors and force flash, which then worked! Check out my signature for the video of the process, and in the description of the video I actually created a Google Doc with all the commands (force flash as well).
For hardware h264 enc/dec with a NVIDIA card you need a cpu with an embedded gpu, as h264 enc/dec is made by embedded gpu not with discrete NVIDIA card, it's not supported.
It's not the case with AMD cards, enc/dec for h264 and hevc is made by discrete AMD cards.
Big Sur will support by default only 2014+ iMacs... I wonder if our "obsolete" macs can still be hacked to make it work. Its an interesting challenge for sure

This report is concerning, looks like, at a glance, NO NVIDIA graphics support. We will have to wait for the deep divers to determine, but all "supported" Mac models use Intel or AMD graphics.
Buy AMD while you can!!! (Kidding here!)
I think that the development of this will have big impact on the cards that should be recommended here for a long term support. If I recall correctly AMD was mentioned on several occasions as the "future proof GPU", seems rightly...
Oh, and there is already a thread > https://forums.macrumors.com/threads/macos-11-big-sur-on-unsupported-macs-thread.2242172/

Pretty expensive, but this one looks interesting, especially because of the smaller form-factor and performance: https://item.taobao.com/item.htm?sp...y52uFX&id=560931870718&ns=1&abbucket=5#detail
Also RX560 external gpu is supported by MacOS.

There seems to be at least a single late 2013 MacBook Pro 15 with Nvidia GPU supported - so this is not a complete cut? Or it is an error on the Apple website?
Seems that Ivy Bridge models are cutoff. On a first glance looks like a motherboard/CPU cutoff rather than GPU.
There's a 650M on the Early 2013 MBP 15" models, and a 750M on the Late 2013 MBP 15" Models. Still a 750M on the 2014 MBP 15" Models as well. It's not until the Mid-2015's that they switch to all AMD cards.

Hey guys, I tested my wx7100 on another imac 27 2010, using the opencore iso that Nick created worked perfectly scoring a decent 1200 in Unigen Heaven. was detected with all the 8GB of ram and all, but unfortunately i was testing the target display mode command and the screen became dark and didn't do much. So i restarted and now even if with the opencore inserted i see the apple logo and progression bar, when the OS starts the screen remain always black. I tried a PRAM reset and everything and with screen sharing the imac detect a wx7100 but doesn't show the 8gb of ram no more in "About this Mac". Can you help me to go back to were i was?
This post explains everything. https://forums.macrumors.com/thread....1596614/page-214?post=28339811#post-28339811what do I have to config to get
A) Catalina Bootloader to pick Macintosh HD by default
B) count to 3 and boot A)
C) hide "Catalina Loader" from my Desktop
so I can enjoy a "vanilla experience" as much as possible.
thanks
