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.

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

aben Posted April 23, 2022 Share Posted April 23, 2022 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 Link to comment https://www.insanelymac.com/forum/topic/351507-haswell-hd4600-pc-stuck-at-boot-with-igpu/#findComment-2780876 Share on other sites More sharing options...

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.

aben Posted April 23, 2022 Share Posted April 23, 2022 Sounds like the dGU is the main display driver here. Try this config.plist attached below. If this too doesn't work, then I'm not sure what other solutions are possible. config.plist.zip Link to comment https://www.insanelymac.com/forum/topic/351507-haswell-hd4600-pc-stuck-at-boot-with-igpu/#findComment-2780879 Share on other sites More sharing options...

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.

Slice Posted April 25, 2022 Share Posted April 25, 2022 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 On 4/23/2022 at 7:12 PM, Hervé said: Regarding your properties injection for graphics, no need to inject device-id Thank you.

erfto1 Posted April 29, 2022 Author Share Posted April 29, 2022 On 4/27/2022 at 10:49 PM, Hervé said: 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 ?

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.
