![]() ![]() The reason why this is important is due to the amount of iGPU configurations Apple supports in the iGPU kexts, specifically known as framebuffer personalities. Commonly seen with iMacs that include dGPUs.iGPU is solely used for internal compute, and dGPU handles all display outputs.iGPU is only used for internal displays, and dGPUs are handling external displays.Commonly seen on Mac Minis, MacBook Airs, 13" MacBook Pros and iMacs without a dGPU. ![]() Property used by macOS to determine the framebuffer profile with Sandy Bridgeīefore we jump too deep into this rabbit hole, we should first explain what we're doing and why we need to do this.īy default in Macs with iGPUs, there are a few configurations: Property used by macOS to determine the framebuffer profile with Ivy Bridge and newer Kext used to patch GPU drivers to better support PC hardware Profile in a framebuffer which determines how the iGPU will act Refers to the kext used in macOS to drive a GPU ![]() Note this guide is not a beginners tutorial, we recommend you follow the recommend iGPU properties listed in the ist section of the guide to start off. This guide will be a more in-depth look into patching macOS to support more hardware variations of Intel's iGPUs including proper display out, fixing color tint issues, HiDPI issues and etc.
