Get stuck when changing from iMacPro1,1 to iMac20,2

Open scyu6058 opened this issue 3 years ago • 5 comments

I have almost the same configurations except that I used internal AMD display card. Everything works fine when using the provided EFI. But when I attempted to change the SMBIOS to iMac20,2, the system stopped at the log-in page with mouse and keyboard all frozen up. Any idea, please.

Hi there. Did you disabled the integrated GPU in the BIOS or you leave it "automatic"?

But seems the USB Mapping kext was built specifically for iMacPro1,1. Anyway, I'll try as highlighted.

Surely USB Mapping on iMacPro1,1 SMBIOS needs the XHC1 renamd to SHCI, but this should not interfere with system startup. You can try with the USBinjectall.kext though, without custom USB mapping.

Yep. The USBMap.kext is specific for iMacPro1,1. Open Package contents, search for the info.plist and then search for "iMacPro1,1" and replace it by "iMac20,2".

But why do you want to use iMac20,2? I would only use it if you have a supported iGPU. But the 11900k has no supported iGPU.

Thanks for the enlightenment.
