I did manage to successfully install Mac OS HighSierra 10.13.3 on my Lenovo C560.

The only things that are left to fix is the glitching in the graphics and the lack of sound.

Looking at the "About Mac" my IGPU has only 7MB assigned.

I've tried:

Installing kexts(Lilu, IntelGraphicsFixup)
Setting my ig-platform-id to recommended values on this/other hackintosh forums(currently set at 0x01660003)
Setting IntelGFX under FakeID to 0x0 which resulted in a glitchy boot with stripes all over the screen(currently set at 0x12345678 working)
Using Intel FB-Patcher by headkaze(Set IntelGen to Haswell and PlatformId to 0x0412000B) applied patch with General-->Devices / Properties --> Connectors and VRAM checked to config.plist(the result output attached "FBPATCHRESULT.txt")

Screenshots of some details about the system and config.plist attached.

That is not a valid ig-platform-id.
Haswell desktops typically use 0x0d220003.

I did state that I tried some recomended platform ids and the one you gave me was one of those, it actually makes my pc unable to boot up(it restarts after loading bar is at 1/3 progress with a graphics glitch appearing at the top of the screen in the moment of restart)
 
I also have Win10 installed on the same PC.

Hope this can help in any way.
 
Removed IntelGraphicsFixup added Whatevergreen. Now I'm able to boot with valid platform id but the screen is glitched(photo attached below)

After using -igfxvesa boot flag it boots with no glitches but still with 7MB vram

Experiment with other valid ig-platform-id values.
Your AIO probably has an eDP display, which may not be supported.

It turned out to be a problem with with IntelGraphicsFixup kext. After removing it and adding Whatevergreen it boots up with glitched screen(image in the posts above) using Fake id: 0x0 and the 0x0d220003 platform id. Changing fake id to 0x12345678 makes the pc boot up without the glitch but still with 7mb vram. Also using -igfxvesa bootflag it does boot up with 7mb no glitch.

No expectation of working graphics when using an invalid ig-platform-id.

I have the same problem as you.
