As expected, macOS fails to find the monitor which results in black screen. There's a guide on Injecting EDID. Check that out. Also, just enabling the connectors will not help. You must define the connectors as well.

The above IOReg shows that the IGPU is disabled via the boot arg "-igfxvesa". If you're getting black screen, then you can use VNC viewer to patch the connectors. If that doesn't work for you, simply patch the connectors blindly. Define con1, con2 and set them as 00080000 and 04000000. If it...

Okay, fair enough. Check DM.

Black screen means the system booted up fine but there is no display. Two things to do here: - Patch the connectors - Inject EDID if it doesn't work even after patching connectors See Patching Connectors below...

You're using a CFL ig-platform-id. Ensure the following: - DVMT set to 64MB in BIOS - ig-platform-id to 00001259 - stolenmem shouldn't be required in your case when you set the DVMT in BIOS. - Remove -igfxvesa boot arg. If you get a black screen, then you need to patch connectors accordingly.

Oh, that's weird. However, we managed to fix several devices where manufacturers discontinued the support. Before the debug, was it working fine on Big Sur with your hardware?

Attach the EFI to check!

Yes, indeed.

Did you forgot the password? Thanks for maintaining the guide! Yes, its sad but it was a great journey. Apple will probably remove the X86_X64 support by next year!

High Sierra will have native support. Else, you can use higher version and patch the IGPU as NVIDIA drivers are still experimental.

Happy to hear. Yes, one must map the ports accordingly to boot macOS Tahoe.

Great. Marking Solved and closing this thread.

Do you have a working confirmation? Probably, GT520 should be supported.

Umm, there wasn't one. You might have read that in the Thunderbolt guide where few Audio Interface were tested. Never heard about that. In which slot you have it plugged? Use the siot from CPU and that way you will have less latency. It could be also possible that something else is interfering...

Was the panel replaced and did it work fine with the previous macOS?
