HP Pavilion x360 (no graphics)

Hello everybody!

I am trying to get graphics on my machine. CPU: i5 4210u

I have seen Toshiva's (Toshiba Satellite Pro R50-B.)post and inspired by him to do my OpenCore Config, but I still don't get an image. When I type the "devide-id" I get a black screen with script loaded. I can get sound.

Can anyone help? thnx

There is absolutely no need to patch the Haswell framebuffer memory size on Haswell mobile HD4x00.

The only thing that needs patching is the HDMI connector if HDMI output is to be used (or system will freeze/crash).

The other thing that may need patching is the cursor memory size (to be set to 9MB) if glitches are experienced.

 

The correct settings required to obtain graphics acceleration on Haswell laptop with HD4200/4400/4600 graphics are:

1) use of Lilu + Whetvergreen kexts (WEG normally takes care of iGPU ACPI device renaming to IGPU).

2)injection of the following properties against iGPU@2 (i.e. location PciRoot(0x0)/Pci(0x2,0x0) in Device Properties section of the bootloader config):

AAPL,ig-platform-id    0600260A    DATA
device-id              12040000    DATA

3) SMBIOS of MacBookAir6,2 or MacBookPro11,1

 

This being, said, please post:

1) your full systems hardware specs. Add them in your signature like most of us do, as expected.

2) a zipped copy of the OC or Clover EFI folder you're using.

3) the version of the bootloader you're using.

4) the target macOS version you try to install/run.

Thanks for joining the conversation.

I already tried these parameters with no result. System loads, but black screen.

I am installing Big Sur 11.0.1

8gb RAM ddr3

Open Core 0.6.7

No quoting to post replies please; especially if you use Google translator... Just use the Reply box at the bottom of our pages. As a newcomer, I also invite you to read our published rules so that you get familiar with them.

 

Setup is incorrect in a few respects, most of them minor:

  • you use old versions for some of your kexts; update them to the latest versions (eg: Whatevergreen)
  • you've enabled _OSI to XOSI renaming but not the SSDT-XOSI table; these go together...
  • you have some unnecessary kernel quirks enabled (eg: AppleCpuPmCfgLock which is for Sandy/Ivy Bridge)

The one thing you must do is update Lilu & WhateverGreen to the latest version.

At your next reboot, make sure you Reset NVRAM at the OC Picker.

 

If you still get back screen, you could require to inject your screen's EDID. You can obtain it from Windows with some tools that you can Google for.

I have done everything you describe to me with the same result.

I am going to install Windows and get that information. Once I have that data, how do I have to write in config.plist?

You can inject EDID info through a device property against your iGPU, i.e. alongside what you currently inject (i.e. ig-platform-id and device-id). Look it up in the WhateverGreen User manual.

You may also want to connect a VGA monitor if you have that around you and, hopefully, get the macOS desktop or whatever on screen. VGA usually is supported OOB on laptops with HD4400 graphics (they're the lucky ones!)

 

By the way, what do you mean by "I get a black screen with script loaded"?

I hadn't understood correctly, I'm sorry.

I have already exported a set of files and read the guide, but honestly, I don't quite understand what numberings I should put in section AAPL00 ... etc.

Could you tell me what lines should I include in the properties?

You enter the whole set of hexadecimal obtained as EDID from Windows or whatever you used to extract it. It's the data provided at the bottom of that Nuevo document de texto.txt text file:

Raw data
  00,FF,FF,FF,FF,FF,FF,00,36,7F,03,90,08,00,00,00,00,01,01,03,80,00,00,FF,2F,00,00,A0,57,49,9B,26,
  10,48,4F,00,00,00,01,01,01,01,01,01,01,01,01,01,01,01,01,01,01,01,66,21,56,AA,51,00,1E,30,46,90,
  14,00,00,00,00,00,00,18,00,00,00,FC,00,4E,6F,74,65,62,6F,6F,6B,50,61,6E,65,6C,00,00,00,FD,00,3B,
  3C,2F,30,09,01,00,00,00,00,00,00,00,00,00,00,10,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,09

 

You take all the hexadecimal data, remove the separating commas and enter the complete set of bytes in a single long chain of data:

AAPL00,override-no-connect     00FFFFFFFFFFFF0036 ....... 0000000009    DATA
