<< Solved >> System freezing after 5 to 15 minutes of inactivity(macOs Catalina 10.15.6, Z390+i9 9900K)

[Mac-Z]

The system gets frozen while there are no activities after 5 to 15 minutes, normally it happens at around 10 minutes, sometimes the mouse pointer is still moveable for a while. I have tried to delete NVMeFix.kext and also prevent the hard disk to sleep, but they did not work.

OpenCore bootloader 0.6.0

Thank you!

The problem is not there anymore. I just updated to OpenCore 0.6.1 and config everything from scratch again. no idea what was the root reason.
