Big Sur...BIG Problem

[Ritesh]

Thanks for your time,but by using your attached EFI folder my screen goes blank
so i have figured out something..i have added some device properties i can able to get the display directly to HDMI port,but no GPU acceleration.i am attaching my screen shot...have a look.

and also i have changed by SMBIOS to 19.2 because it is closed to my Configuration.

Thanks and regards.

Hi,

My system (see closed issue above) is just updating correctly to 10.15.5. Just to inform to everyone with this error. I solved it by changing igpu platform id to 3E9B0000 (before I had 3E9B0007) and made a correct frame buffer conector patch. Don't update to 10.15.5 until you have 10.15.4 working with full graphics acceleration, all with 3E9B0000 and your framebuffer patch.​

If you had previous frame buffer patches (with 3E9B0007) you have to modify them, and watch out indexes values specially. You can solve it, but you have to patch your connectors properly​

Regards!​

iMac19,1 is a better choice

also don't forget to change it in your info.plist in your usb kext

also while you are in there, remove any unneeded ports

I dont know how to change SMBIOS in usb.kext
and before Compile the USB kext have removed unneeded ports..

as you can see their is only one empty port and that is type C.
