I was able to boot fine without igpu but its unusable without it,i guess i my config is wrong,what can i do ?

 

It gets to the apple logo but gets stuck halfway loading

 

Also i cant get verbose to work again after disabling it.

 

Thanks,my specs are in my signature

Hmm... post a zipped copy of your bootloader EFI folder maybe?

 

Desktop HD4600 graphics should be support OOB with the usual Azul framebuffer layout and, most probably, correct SMBIOS. iMac14,4 should be used for Big Sur.

Thanks,ill try imac14,4

 

Here i uploaded my EFI

Thanks

I found out my igpu wasnt enabled in bios,i enabled it but i still cant manage to boot

 

IGPU doesnt seem to work now,ı get stuck at gIOScreenlockstate.Device properties etc.is ok.

 

I saw other people also have issues like this but not what its causing this or a solution,what can i do ?

 

Thanks.

You probably need to disable the Nvidia dGPU as well; either via a BIOS toggle or SSDT.  Try your luck with boot-arg flag: -wegnoegpu

Thanks but thats my problem,whenever i try to disable dgpu with -wegnoegpu or device properties pc doesnt boot.

 

İf i dont disable it shows dgpu with 8mb memory and no igpu.

The dGPU is Maxwell and will be of no issue in Big Sur given that there are no drivers. As long as your iGPU is the selected GPU in BIOS, it should be Ok for macOS. In all cases, the boot arg -wegnoegpu would certainly sort this out.

Regarding your properties injection for graphics, no need to inject device-id (your iGPU's own native id IS 0x0412) nor to patch the framebuffer memory settings. As such, injecting the framebuffer layout-id + the optional slot + iGPU description strings should suffice.

Re: NVRAM properties, change the car-active-config settings you've used from 0xFFF (FF0F0000) to 0xFEF (EF0F0000).

Hmm,i tried everything i could find but im still unable to boot,i get wake failure at boot

 

Also my monitor is connected with VGA cable ive seen its not supported ? That might be the problem ?

Recommended to utilize modern display connectors like HDMI or DP, especially on current macOS releases like Big Sur (Apple loves to drop support for old-gen specs, this is obviously expected knowing Apple). However, in your case, HDMI output will still be driven by the dGPU (Maxwell cards natively supported only till macOS High Sierra, as far as I'm aware) therefore I highly doubt your current system config would have any native support on current macOS releases.

Last tested AMD HD6450 had working VGA output (in Sierra?) but more recent card RX570 has no VGA connector at all.

So i switch from VGA to a DVI cable cable but opencore is still not booting,i gets to opencore picker again after failing also im catalina

 

I guess its my config or something else now,my device properties are like this

PciRoot(0x0)/Pci(0x2,0x0)

AAPL,ig-platform-id = 0300220D
AAPL,slot-name = Built-In
model = HD 4600

İ5 44460 HD 4600

İs this wrong ? I deleted device-id

Also the cable is connected throught the egpu port if that makes a difference

Regarding your properties injection for graphics, no need to inject device-id

 

Thank you.

What on earth do you mean by that? DVI port out of the unsupported nVidia Maxwell card or the built-in DVI port?

 

Your iGPU properties injection is spot on for an HD4600 desktop computer.

Yes it was connected to dvı port out of maxwell gpu,now i connected it to motherboard port and no difference

 

I changed and tried a premade config for i54460 but that doesnt work either

 

I dont know whats wrong but at the end i installed high sierra and web driver for my gpu,igpu still not working :(

 

Thanks,maybe something is wrong with my hardware ?

Clearly you were not going to get any video output with the DVI cable in the nVidia card when meant to be using the HD4600 iGPU...

What if you actually take out the nVidia card? Did you try that?

And sorry for asking but are you sure your desktop is fitted with an i5-4460 CPU and not a different model that may not have iGPU?

Yes,im sure it's i5 4460

I didnt try taking out the nvidia card but it gets disabled normally.

Problem was the Nvidia card, I took it out and its booting and working nice now.

Better than having to disable the other card

 

Kind regards.
