Support of Quadro K2000M Graphic cards on iMac's Mid 2011, 21,5" and 27" versions

[FrediSwiss]

I could use Macos Sonoma version 14.7.6 on my both iMac's in the past. That means, I could start the iMac's. Later versions have the problem, that the installer runs thru until the last sequence of the installing process, then the start is blocked. I am able to start the iMac's with the shift key, a white background appears. I tried to install the graphic driver with OCLP but the result remains. I can not start my iMac's.
This is a bit annoying. So help is needed.

Waiting for reply. Thank you for your support.
Best regards, Fredi

It seems that macos Sonoma 14.8.3 (23J220) can only loaded in safe mode due to a problem loading the wrong the graphic driver. The WiFi connection is ok. I tried to reload the graphic driver with OCLP, but the problem remains.
It has probably to do with the fact that iMac's build 2011 have a different type of graphic system. "It would be helpful if this issue could be solved with OpenCore Legacy Patcher version 2.4.1 or newer."
