I am on 3600 and 5700 on OpenCore and 10.15.1,
I boot into the system and the issue is that if I don't touch the system or I am away from the mouse and keyboard, the system will freeze after a few minutes, and the system report it restarted after a panic and

The report :

I thought I got a fix by updating from beta to release, but end up the issue is still here ...
I am looking for a help or a fix .... please help ....


Disable Sleep in the system settings.
My computer got kernel panic even when I'm using it, sometimes it panics from the sleep. I tried to fix in many ways but doesn't work, then I gave it up and using Linux. But it turns out that I got the same issue on Linux too, then I found that it is the issue of the hard wares, the RAM timing, voltage and clock. I fixed it and still monitor for a few weeks, if the issue with the hardware is fixed I will try hackintosh again and let you know. May you got the same problem with me :thumbup:
Same issue here. :(

Already did that but it freezes anyway. Disabled screensaver as well... don't have a clue of what's happening. My temp fix is to open some fireplace video on youtube while im out.
This is an issue with NullCPUPowerManagement.kext. Replace with this version,

Thanks, i am gonna try that,
i actually fixed it by using a music player called JOOX and keep playing music, sometimes when i forgot to open the music player, it freeze, so i click report to show report and then it won't freeze even without playing music, but it freeze after updating macOS,
anyways i will try that kext and see if it fix the issue, thanks !
