![]() DeviceProperties -> Add -> PciRoot(0x0)/Pci(0x2,0x0) has been correctly setup.kextstat | grep -E "Lilu|WhateverGreen".To verify if they loaded correctly in macOS, run the below command(if nothing is outputted, the kexts are not loading).Lilu and WhateverGreen are present under EFI/OC/Kexts and in your ist.We'll need to go over some prerequisites first: Now that we've gone over the basics of setting up an iGPU, let's get into some deeper topics. Open your ist and add this new entry under PciRoot(0x0)/Pci(0x2,0x0): Key Now that we have our device-id, we'll do the same thing as before with ig-platform-id. # Next reverse it, but keep the pairs in tact # First, remove 0x and pad it to 8 bits by using 0's in front of it Using Intel's ARK page (opens new window), we can see the following: To determine whether you need a new device-id injected, you'll want to compare WhateverGreen's list of supported IDs (opens new window) to what you have.įor this example, lets take a look at the i3-4150 with an HD 4400 iGPU. Why this is important for us is that Apple's iGPU drivers have a limited amount of IDs even though the kext itself can support much more. This is the location of Intel's iGPUs relative to the IOService path, and has been consistent as far back as Yonah series CPUs(2007+): Keyĭevice-id is what macOS, or more specifically IOKit, uses to determine which devices are allowed to connect to which drivers. Now we'll want to add a new Entry called PciRoot(0x0)/Pci(0x2,0x0). # And now you have your final framebuffer profileįrom here, lets open up our ist and head to DeviceProperties -> Add. # Next, reverse the order but keep the pairs together # To start, remove the 0x and then space them out in pairs If you scroll to the bottom of this list, you're also given some recommended options: ![]() Mobile vs desktop), VRAM requirements, etc. Here we're given a list of all supported framebuffers in macOS, including the hardware type(ie. We'll first want to scroll down the manual until we hit the Intel HD Graphics 4200-5200 (Haswell processors) (opens new window) entry. A full list of these values can be found in WhateverGreen's manual: .md (opens new window)įor this example, lets try to find a framebuffer compatible for a desktop HD 4600 iGPU. The format of this entry is hexadecimal, and is byte swapped from the actual value.
