My Hackintosh is mostly working, but there are a few issues:

The biggest is that I’m unable to unstall the past 2 High Sierra updates, as doing so introduces a horrible flicker that makes the system unusable.

Next, wake from sleep doesn’t work, as the system refuses to wake.

Thirdly, a recent phenomenon occurs whenever I open Firefox: the aforementioned screen flicker suddenly appears, making a shut down and start up necessary. I’ve found that restarting does not vanquish the flicker.

My mobo is an MSI Z370I Pro Carbon Gaming. It has a 3.7Ghz i7-8700 with 32GB Corsair RAM and 1TB SSD. I’m using integrated graphics with a 4K Acer monitor over DisplayPort.

Any suggestions that might help would be welcome!

Not having graphical acceleration can cause screen flickering are you sure you have acceleration after updating?

I don't know how to determine whether acceleration is activated. Does the attached reveal whether it is or not?

Thanks!

Yes...I'm currently running 10.13.3, and three times I tried updating to 10.13.4 and 10.13.5, but each time resulted in flickering. I even tried updating to the most recent kexts, but that didn't kill the flickering, so I had to revert to my 10.13.3 backup.

You can tell by looking at the Dock. If it's white that means you don't have acceleration if it's transparent and shows blur you have acceleration. Take a screenshot of macOS High Sierra with the default high sierra background and post it here if you can't tell and I should be able to tell you.

Here's a screen grab...it appears acceleration is working...

Its the older, mostly stable (so long as I don’t open Firefox, that is) version, 10.3.3.

Would choosing iMac 18,1 in SMBIOS in Clover stop the flickering? That's what I've been doing since High Sierra.

I just changed it to 18,1, and there's no longer a flicker when opening Firefox (whew).

Next I will need to perform a clone backup before crossing my fingers and attempting the update to 10.3.5. Thanks, and stay tuned!
