[SOLVED] Screen freezes randomly every 1-2 days

[mm00]

I have an issue with my configuration. The screen freezes randomly every 1 or 2 days. The interesting part that not the whole OS freezes as the music continues to play, but the screen stuck at a single frame without any change.

You can find my config on my profile and also attache the gen_debug to this post. I created it right after the freeze. The freeze was around Dec 6 09:32 - 09:35

If you have another mac, enable screen sharing on your hackintosh and try to access it from the other mac.

If you can connect and see the display, it means your GPU framebuffer crashed and is unable to restart.

That can be caused by an app (fantastical2 seems to be flooding your system log because it's not properly signed)

Run this terminal command to fix it:

sudo xattr -rd com.apple.quarantine /Applications/Fantastical\ 2.app

Thanks Namok88, I removed Fantastical to see if the problems happens again. I will post when it's happening again.

Well, it happened again. system.log attached and it was around Dec 7 10:15
Also I was not able to connect with screen sharing.

I just enabled iGPU in BIOS to see if it makes any difference. This topic gave the idea: https://www.tonymacx86.com/threads/...s-with-com-apple-dumpgpurestart.252459/page-3

AFAIK, DumGPURestarts happen when the GPU is crashing.

Looks like you have a faulty GPU board. Try booting from a Win 10 or Linux LiveCD and let it run for 2 days to see if it still crashes.

If the crashes still occur, you might want to consider replacing it.

Since we removed and installed Fantastical 2 again the freezing issue solved.
