Dell latitude E5430 graphic support - Help please!

3 posts in this topic

Recommended Posts

Hello!

 
I'd like to ask for some help with the installation of OS X 10.11.6 on a Dell latitude E5430.
The problem is, that I can't get to the installation screen.
More precisely, when I get there the screen glitches out so I can't even start the installation. After connecting the laptop to an external monitor the install screen appears with a cursor but the screen is still completely unreadable...
I'm not an expert but I think the problem is somewhere in the video support... So I've tried several guides and fixes but none of them worked for me. (I managed to get past a missing IOBluetooth panic by using a patched dsdt)
 
With a combination of different config settings, dsdts and kexts I managed to reach the installation screen but only without any input at all... After fixing the input problem the screen was gone again...
 
Do you have any similar experience? Please help if you have any idea for a solution!
Thank you in advance,
 
MadFive

I have 6430 with the same CPU, it is IvyBridge. Same screen.

The graphics works with Inject->intel=YES

ig-platform-id=0x01660003

I also have Nvidia NVS5200M. It is not working, so I set Optimus=Enable in BIOS. Yes, enable!

 

EDIT1:

Looking your config I notice you did the same, but

InjectEDID=YES is obsolete

you have to write

EDID->Inject=YES

 

And I set DualLink=1

DualLink is not normally required on low-res LCD; only on high res models (1600x900 and above) with which you must also use layout-id 0x01660004.

 

Use MacBookPro9,2 SMBIOS, not MBP8,1 which is SandyBridge/HD3000...

 

Here's your revised DSDT where _DSM method of Device (IGPU) has been modified as follows:

  1. layout-id changed from hires 01660004 to lores 01660003
  2. Dualink changed from 1 to 0

Give that a try.

And here's a revised Clover config.plist because yours was quite messy and erroneous (devices, patches, SMBIOS, etc.).

      I'm not expecting too much help, but if anyone has any suggestions, that would be great.

      I recently got my Hackintosh running on macOS 10.14, and went to install the graphics drivers for my Nvidia GeForce GTX 750 Ti. My setup is a little different, so here it is:

      Screen 1 Screen 2 Screen 3

      Screen 1 and 2 are both connected to my 750 Ti, whereas screen 3 is connected to my iGPU, with is an intel HD 4600. The intel GPU works like a charm, just as it did under High Sierra.

      Now, I got the Nvidia Web drivers to "work" by removing any traces via the "Web Driver Toolkit" that others have recommended. I then patched the installer, installed it, rebooted, patched the installed drivers, and rebooted again, where the drivers are at their current state.

      This is where things get interesting though. All 3 monitors are recognized. My GPU is recognized in my system profiler. However, it is NOT able to be used to run a compute in Geekbench, meaning that GPU acceleration is obviously disabled. The other thing that doesn't work, is, well, the 2 monitors connected to the GPU. They are set to the correct resolution and refresh rates, and are recognized in System Preferences, and I can even drag things between the different desktops.

      But I can only see my cursor. The screens are totally black, and I can't see anything on them except my cursor moving across them. Has this happened to anyone else? Thanks in advance!

      Specs:
      Asrock B85M-Pro4 Motherboard
      Intel Core i5-4690 CPU
      Intel HD 4600 GPU 1
      Nvidia GeForce GTX 750 Ti GPU 2
      iMac 15,1 SMBIOS

      Here is a picture of what happens
