Flicker after installing 10.13.4 update

[oadesign]

When updating to 10.13.4, the installer ran twice, and then finally after 3 boots, the system booted successfully, however my HD630 graphics are now flickering badly.

I then updated both Lilu.kext and IntelGraphicsFixup.kext, but the flickering persists.

Does anyone have any ideas as to what might be causing this, or where I should make changes to try to eliminate the flicker?

Thanks!

No "Problem Reporting" files attached.
Read FAQ, "Problem Reporting" again. Carefully. Attach all requested files/output.

Use the gen_debug.sh tool mentioned in the FAQ, that way it is less likely you'll omit something.

upload your config and a screenshot of your efi/other folder.

A screen grab of my 'Other' folder is attached, along with my config.

Thanks!

Thanks! Even though it's a laptop FAQ, I read everything, and found helpful info near the bottom (Q. What are typical "Problem Reporting" files?).

I downloaded and installed the debug tool. But when I ran it (while running my clone backup of 10.13.3), Terminal reported a 'command not found' on line 54.

Hopefully the config.plist and 'Other' kext folder grab I uploaded will help to diagnose the issue. If not, I can try updating to 10.13.4 again and running the debug script, but it may be a challenge to do so with the screen flicker...

Thank again!

try iMac18,1 - 18,3 requires gpu, also you had nvidia set to true

Thanks...I changed the ID to 18,1 and changed the Nvidia to false, but the flicker still persists!

Yes, the system was stable and everything worked. Even sleep/wake from sleep worked perfectly. I've since gone back to 10.13.3 via my external clone.

I've attached the system report > Graphics/Displays, but don't know if acceleration is active...how can this be determined?

Thanks!
