[solved] Iris 550 Issues

[romsfreak]

Hi!

Unfortunately MacOS Sierra shows 7MB as video memory of the Intel Iris Graphics 550 (and I also get slow animations and sometimes flickering.
I've always patched minStolenSize because Bios default DVMT-prealloc is set to 32mb and I can't change. Also Intel is injected, ig-platform-id set to 0x19160000 and FakeID/IntelGFX to 0x19168086. And I'm using FakePCIID.kext and FakePCIID_Intel_HD_Graphics.kext.

Can someone please help me?

config.plist and screenshot attached.

Thanks in advance.

Damaged kexts, relatively obvious from kextcache output:

AppleIntelSKLGraphicsFramebuffer.kext has incorrect permissions; omitting.

Run the macOS installer to restore your kexts to vanilla.

Done. Thank you.

New output of kextstat:

Should I try minStolenSize patch again now?

If you have no ability to change DVMT-prealloc to 64mb or larger, you will need to use the minStolenSize patch.

Got it work, it shows 1536MB (which is still not enough).
But now there is some flickering at the top left corner. How can I fix it?

It is correct.

I guess you missed the pinned thread.

Really? Thought it has to be 4180MB.

Oh, of course. Sorry for this mistake.

No idea where you get that number.
