Please help with my Sierra Graphics problem (Desktop HD4400)

Hello everyone. I recently installed macOS Sierra 10.12.3 on my Lenovo ThinkCentre M73 Tiny. It has the following specs:

  • Intel Core i3-4170T @ 3.2GHz
  • Intel HD Graphics 4400
  • 8 gigs of DDR3 memory @ 1600MHz
  • 60 gigs of Kingston SSD (SV300)

I also got the following BIOS settings: * Select Active Video (IGD) [i dont have Discrete graphics, thats it) * Pre-Allocated Memory Size: 64MB (it could go up to 1024MB) * Total Graphics Memory: Maximum * CPU Setup: Intel Virtualization Technology: Disabled * CPU Setup: Hyper Threading Technology: Enabled * CPU Setup: Core Multi-Processing: Enabled * CPU Setup: EIST Support: Enabled * CPU Setup: C State Support: C1C3C6 (whatever this means) * CSM: Disabled * Boot Mode: UEFI Only * Quick Boot: Enabled

When I install macOS, and Inject FakePCIID.kext and the FakePCIID_HD4600_HD4400.kext with Kext Wizard (but I also tried placing it in Clover's kext folder or DPCIManager) nothing happens. And by nothing, I mean that macOS runs on native resolution (1920x1080 via DisplayPort), but the graphics is buggy, flickers, basically no QE/CI.

The "About this Mac" shows that i have "Intel HD Graphics 4400 7MB".

In Clover, i also did:

  • Inject Intel: True
  • IntelGFX: 0x04128086
  • ig-platform-id: 0x0d220003

I can provide full IOReg and outputs, here is the link: link!

I will not provide information about where I downloaded my macOS. In an other forum, i got banned just for this. I can probably say that it is not from the official App Store.

I'd love to experience macOS before I buy a real one, that is why i need some help now in order to make my HD 4400 have the best on macOS.
